Quantum Computing Workshop
2025-02-28 08:00 - 2025-03-21 20:00 (Europe/Madrid) | Santiago de Compostela, Rúa de José María Suárez Núñez, s/n, Santiago de Compostela, A Coruña, 15782, Spain
The workshop consists of 3 Friday afternoon sessions on February 28, February 7 and March 14, 2025 from 15-19 hrs, and a full day Hackathon on Firday March 21, 2025.
Quantum Computing will allow, when sufficiently mature, to tackle problems whose complexity scales exponentially and are, therefore, beyond the reach of classical computing resources.
The advent of fully functional quantum computers is still some years ahead. Meanwhile, a class of strategies have been put forward in order to profit from the available infrastructures.
In this workshop we will show how to make use of those strategies in order to tackle real problems. The program will include both theoretical lectures as well as hands-on sessions. It will end up with a Hackaton where teams will address a particular set of proposed projects.
The level will be introductory and only requisits are basic knowledge of linear algebra and of programming in python.

Title: A Quantum Annealing Protocol to Solve the Nuclear Shell Model
Abstract: The nuclear shell model accurately describes the structure and dynamics of atomic nuclei. However, the exponential scaling of the basis size with the number of degrees of freedom hampers a direct numerical solution for heavy nuclei. In this talk, I present a quantum annealing protocol to obtain nuclear ground states. I propose a tailored driver Hamiltonian that preserves a large gap and validate our approach in a dozen nuclei with basis sizes up to 10^5 using classical simulations of the annealing evolution. I show the relation between the spectral gap and the total time of the annealing protocol, assessing its accuracy by comparing the fidelity and energy relative error to classical benchmarks. While the nuclear Hamiltonian is non-local and thus challenging to implement in current setups, the estimated computational cost of our annealing protocol on quantum circuits is polynomial in the many-body basis size, paving the way to study heavier nuclei.

Title: Quantum Computing Enhanced Sensing
Abstract: Quantum computing and quantum sensing represent two distinct frontiers of quantum information science. In this work, we harness quantum computing to solve a fundamental and practically important sensing problem: the detection of weak oscillating fields with unknown strength and frequency. We present a quantum computing enhanced sensing protocol that outperforms all existing approaches. Furthermore, we prove our approach is optimal by establishing the Grover-Heisenberg limit — a fundamental lower bound on the minimum sensing time. The key idea is to robustly digitize the continuous, analog signal into a discrete operation, which is then integrated into a quantum algorithm. Our metrological gain originates from quantum computation, distinguishing our protocol from conventional sensing approaches. Indeed, we prove that broad classes of protocols based on quantum Fisher information, finite-lifetime quantum memory, or classical signal processing are strictly less powerful. Our protocol is compatible with multiple experimental platforms. We propose and analyze a proof-of-principle experiment using nitrogen-vacancy centers, where meaningful improvements are achievable using current technology. This work establishes quantum computation as a powerful new resource for advancing sensing capabilities.

Title: Towards Quantum Simulation with Trapped-Ion qudits
Abstract: Today’s quantum computers almost exclusively follow the binary paradigm of their classical predecessor. Yet, the applications for such devices, most notably the simulation of physics and chemistry, often do not fit this paradigm. Natural systems come in a variety of spin dimensions and rarely have just two possible states. Quantum processors that natively support multi-level, qudit, operation give us a new tool for addressing the challenge of simulating nature efficiently. I will discuss qudit quantum computing with trapped ions at the example of first quantum simulations with relevance to high-energy physics.

Title: Quantum Computing with a purpose – how do we decide when a solution path is beneficial?
Abstract: To prove useful, quantum computing needs to outperform classical algorithms on practically relevant applications. With the simultaneous advances in hardware, theory, software and applications driven by a highly diverse and interdisciplinary research community, it is easy to lose track of this ultimate goal. In this seminar, we discuss how application-driven research can help bridge the gap between the technology and its end users. Topics include the interplay of the classical and quantum parts of a full solution pipeline, how to build towards abstraction layers, and an in-depth discussion of https://arxiv.org/abs/2503.14696 highlighting a central obstacle in the application of variational algorithms in the context of near-term quantum computing.

Title: Distributed Quantum Circuit Cutting for Hybrid Quantum-Classical High-Performance Computing
Abstract: Most quantum computers today are constrained by hardware limitations, particularly the number of available qubits, causing significant
challenges for executing large-scale quantum algorithms. Circuit cutting has emerged as a key technique to overcome these limitations by decomposing large quantum circuits into smaller subcircuits that can be executed independently and later reconstructed. In this work, we introduce Qdislib, a distributed and flexible library for quantum circuit cutting, designed to seamlessly integrate with hybrid quantum-classical high-performance computing (HPC) systems. Qdislib employs a graph-based representation of quantum circuits to enable efficient partitioning, manipulation and execution, supporting both wire cutting and gate cutting techniques. The library is compatible with multiple quantum computing libraries, including Qiskit and Qibo, and leverages distributed computing frameworks to execute subcircuits across CPUs, GPUs, and quantum processing units (QPUs) in a fully parallelized manner. We present a proof of concept demonstrating how Qdislib enables the distributed execution of quantum circuits across heterogeneous computing resources, showcasing its potential for scalable quantum-classical workflows.

Title: Toward Scalable Quantum Computers: Transitioning from Monolithic to Modular Multicore Architectures
Abstract: Current monolithic quantum computers already integrate tens to hundreds of physical, error-prone qubits. A central challenge is scaling these systems to thousands or even millions of qubits to enable the implementation of fault-tolerant error correction protocols, which are essential to unlocking their full computational power. Modular multicore quantum computing architectures have emerged as a promising scalable paradigm. In this talk, we will begin by revisiting the concept of the quantum full-stack, with a particular emphasis on the software layers and core design principles. We will then focus on scalable modular architectures across different quantum hardware platforms, including trapped ions and superconducting qubits. We will discuss the major challenges associated with transitioning from monolithic to multicore architectures, particularly in the context of distributed quantum computations.

Title: Off-diagonal Pauli Weight truncation and equilibration temperature dependence for simulating local dynamics in quantum systems
Abstract: The complexity of simulating the out-of-equilibrium evolution of local operators in the Heisenberg picture is governed by the operator entanglement, which grows linearly in time for generic nonintegrable systems, leading to an exponential increase in computational resources. A promising approach to simplify this challenge involves discarding parts of the operator and focusing on a subspace formed by “light” Pauli strings—strings with few Pauli matrices—as proposed by Rakovszki et al. [Phys. Rev. B 105, 07513 (2022)] for infinite temperature settings.
In our recent works [Phys. Rev. B 111, 094301(2025), In preparation], we investigated whether this strategy can be applied to quenches starting from homogeneous product states, end extend it to handle arbitrary temperatures, since the evolution of ergodic Hamiltonians combined with these initial states grant access to a wide range of equilibration regimes.
By concentrating on the required matrix elements and retaining only the portion of the operator that contains Pauli strings parallel to the initial state, we uncover a complex scenario. For intermediate simulation times, in some cases the light Pauli strings suffice to describe the dynamics, enabling efficient simulation with current algorithms; however, for other cases heavier strings become necessary, pushing computational demands beyond our current capabilities.
For long simulation times, we detect that complexity is intimately correlated with the equilibration temperature, and that our modified method agrees with the state-of-the art transverse contraction simulations. In the process, we found that the transverse light-cone algorithm also displays a complexity correlated with temperature, which can be explained by a careful reinterpretation of our results

Title: Generative quantum advantage for classical and quantum problems

Abstract: Recent breakthroughs in generative machine learning, powered by massive computational resources, have demonstrated unprecedented human-like capabilities. While beyond-classical quantum experiments have generated samples from classically intractable distributions, their complexity has thwarted all efforts in efficient learning.

This challenge has hindered demonstrations of generative quantum advantage: the ability for quantum computers to both learn and generate desired outputs substantially better than classical computers. We resolve this rigorously by introducing generative quantum models that are hard to simulate classically, provably efficiently trainable in every step, exhibit no barren plateaus or proliferating local minima, and generate distributions beyond classical reach with rigorous guarantees.

Using a 68-qubit superconducting quantum processor, we apply these models to two scenarios: learning classically intractable probability distributions and learning quantum circuits for accelerated physical simulation. Our results demonstrate that both learning and sampling are efficient in the current beyond-classical regime, opening new possibilities for quantum-enhanced generative models with provable advantage.

Title: Calibrating a 99.9% Fidelity CZ Gate on a Superconducting Quantum Processor
Abstract: As superconducting Quantum Processing Units (QPU) grow larger, automated and reliable calibration of high-fidelity two-qubit remains one of the main challenges. We introduce a novel gate error characterization method, which we call the Phase-Averaged Leakage Error Amplification (PALEA) protocol, building on Floquet Calibration and Matrix Element Amplification with Dynamical Decoupling (MEADD) protocols. This method is specifically designed to coherently amplify CZ gate errors, especially their associated population leakage to the second excited state of the higher frequency qubit, while remaining robust against other leakage processes. Together with the qubit-coupler coupling optimization, we use it to achieve a CZ gate fidelity of 99.93%, stable over a 40h period, without sacrificing the quality of other operations – we reach simultaneous single-qubit gate fidelities of 99.98%, and readout fidelities over 99.94 % in a single device.

Title: Advances in low-overhead quantum error correction
Abstract: The extremely fragile nature of quantum information implies that quantum error correction (QEC) techniques are going to be necessary to obtain the full benefits that quantum computing offers theoretically. While QEC has been experimentally proven to be effective, it requires significant overheads that should be alleviated. In this talk, I will discuss our recent advances towards low-overhead quantum error correction. First, I will discuss how to leverage biased noise in technologies that do not allow for a bias-preserving CNOT gate (arXiv:2505.17718). Our numerical results imply that up to a 75% qubit reduction can be achieved using the XZZX surface code. Second, quantum low-density parity-check (qLDPC) codes have been recently proposed as viable ways to reduce qubit footprints significantly, but they lack an efficient decoding algorithm. I will introduce our proposal, named Belief Propagation Ordered Tanner Forest (BP+OTF) decoding (arXiv:2409.01440). Numerical simulations show that the BP+OTF decoder achieves similar logical error suppression compared to state-of-the-art inversion-based and matching decoders for bivariate bicycle and surface codes, respectively, while maintaining almost-linear runtime complexity across all stages.

Title: Cooling algorithms for state preparation
Abstract: Preparation of low-energy quantum many-body states has a wide range of applications in quantum information processing and condensed matter physics. Quantum cooling algorithms offer a promising alternative to other methods based, for instance, on variational and adiabatic principles, or on dissipative state preparation.

Title: Entanglement in quantum spin chains is strictly finite at any temperature

Abstract: Entanglement is the hallmark of quantum physics, yet its characterization in interacting many-body systems at thermal equilibrium remains one of the most important challenges in quantum statistical physics. In this talk, Ainesh will show that the Gibbs state of any quantum spin chain can be exactly decomposed into a mixture of matrix product states with a bond dimension that is independent of the system size, at any finite temperature. As a consequence, the Schmidt number, arguably the most stringent measure of bipartite entanglement, is strictly finite for thermal states, even in the thermodynamic limit. The decomposition is explicit and is accompanied by an efficient classical algorithm to sample the resulting matrix product states.

Title: Entanglement Networks for Datacentre-Scale Quantum Computing
Abstract: The quantum computing industry has been sustaining fast progress in scale-up, with quantum processors now demonstrating error-corrected logical qubits and first indications of computational advantage for narrow scientific problems. This talk will look ahead to what we require to reach full commercial advantage, and show that there is a key piece missing: modularity. The scaling path we envisage will entail building multi-core quantum computing clusters at the datacenter scale, and eventually connecting tens or hundreds of modules together to enable multi-million-qubit machines.
This talk will describe our distributed quantum computing architecture underpinned by photonic interconnects. It will outline the technical challenges that need to be overcome to progress the technology, and how Nu Quantum is working to build the pieces needed to scale out towards useful quantum computation.
