Seminario: Conformal quantum cellular automata
Ponente: Lluis Masanes
Abstract: First, I will motivate the use of unitary circuits in quantum many-body physics. Second, I will introduce a family of quantum callular automata in 1+1 dimensions consisting of dual-unitary circuits. The symmetry of these QCAs is a discrete version of the conformal group, hence, these models inheritate many features of conformal field theory. With the same dual unitaries I will construct tensor-network states and interpret them as spatial slices of curved 2+1 discrete geometries. The QCA induces a dynamics on these (bulk) geometries which reproduces gravitational phenomena like gravitational time dilation, the formation of black holes and the growth of their throat.

Seminario: Digital-Analog quantum computing and algorithms
Ponente: Ana Martín Fernández
Fecha: 20/02/2024
Abstract: We will delve into the development and implementation of quantum algorithms using the digital-analog quantum computational (DAQC) paradigm

We will provide a comparative analysis of the performance of DAQC versus traditional digital approaches, particularly in the presence of noise sources from current noisy intermediate-scale quantum (NISQ) devices. The DAQC paradigm combines the strengths of digital and analog quantum computing, offering greater efficiency and precision for implementing quantum algorithms on real hardware. We will focus on the comparison of some quantum algorithms using digital and digital-analog approaches, showing significant advantages in favor of the latter. The findings indicate that the digital-analog paradigm is promising for practical quantum computing applications. Its ability to deliver greater efficiency and accuracy in implementing quantum algorithms on real hardware is a significant advantage over traditional digital approaches.

Seminario: Analog and digital superconducting quantum processors
Ponente: Pol Forn-Díaz
Fecha: 14/02/2024
Abstract: Small-scale prototype quantum processors, despite their imperfections, are already a reality. Multiple physical platforms have reached such a state of development, allowing in some instances access to remote users to program them and run small-scale quantum algorithms.

Enabling the access to such processors is a very important endeavour towards the goal of proving that quantum computation can solve real-world problems of interest. In this presentation, I will introduce the technology of superconducting qubits and I will overview the two potential quantum computing paradigms that are implemented with superconducting circuits: analog and digital quantum computing. In this context, I will introduce the first prototype superconducting quantum processor operating within the context of Quantum Spain at the Barcelona Supercomputing Center.

Seminario: Algorithmic ideas
Ponente: José Ignacio Latorre
Fecha: 6/02/2024
Abstract: Progress in quantum algorithms needs critical revisiting of three relevant steps: encoding, processing and read-out.

Here, we limit ourselves to discuss some ideas related to expressibility of a quantum circuit, and of compressed encoding of information on a ket.

Seminario: Test of the physical significance of Bell’s theorem
Ponente: Adan Cabello
Fecha: 5/12/2023
Abstract: The experimental violation of Bell inequalities implies that at least one of three assumptions, measurement independence (MI), parameter independence (PI), and outcome independence (OI), fails in nature; «one of these three premises must be false, and it is important to locate which one is false» (Shimony,1990)

It is believed, however, that no experiment can decide which is the false one. Here we show that this is not true.

Seminario: Simulating IBM’s Kicked Ising Experiment with Quantum-Inspired Tensor Networks
Ponente: Román Orús, PhD
Fecha: 5/12/2023
Abstract: We show how quantum-inspired 2d tensor networks can be used to efficiently and accurately simulate the largest quantum processors from IBM, namely Eagle (127 qubits), Osprey (433 qubits) and Condor (1121 qubits).

We simulate the dynamics of a complex quantum many-body system — specifically, the kicked Ising experiment considered recently by IBM in Nature 618, p. 500-505 (2023) — using graph-based Projected Entangled Pair States (gPEPS) [PRB 99, 195105 (2019)]. Our results show that simple tensor updates are already sufficient to achieve very large unprecedented accuracy with remarkably low computational resources for this model. Apart from simulating the original experiment for 127 qubits, we also extend our results to 433 and 1121 qubits, and for evolution times around 8 times longer, thus setting a benchmark for the newest quantum processors. We also report accurate simulations for infinitely-many qubits. We discuss also on the implications of these results.

Seminario: PyTheus: automated discovery of quantum experiments
Ponente: Carlos Ruiz Gonzalez, Physicist, PhD Candidate at Max Planck Institute for the Science of Light
Fecha: 02/10/2023
Abstract: Photonic technologies are main players in the second quantum revolution, providing better sensors, secure communications, and quantum-enhanced computation.

Such endeavors require generating specific quantum states or efficiently performing quantum tasks. The design of the corresponding optical experiments, historically powered by human creativity, is being slowly automated by novel algorithms. Unfortunately, these tools are often restricted to very specific use cases and are difficult to generalize, which limits their practical implementation. To overcome these challenges, we developed PyTheus, a highly-efficient, open-source digital discovery framework based on a graph-based representation of optical setups, which includes a wide range of modern experimental devices. PyTheus produces interpretable designs to solve complex experimental problems, like entanglement generation and distribution. Aiming for the simplest solutions, our software provides deeper understanding to human researchers, which can generalize the findings. Therefore, PyTheus can accelerate the development of quantum optics and related technologies.

QTYR23 Workshop
Speakers: varios
Fecha: 4-7 Julio 2023
Abstract: In this lecture, we will review the experimentally feasible algorithmic state-of-the-art quantum computation, namely the Noisy Intermediate-Scale Quantum algorithms (NISQ).

Current quantum computers are composed of a few qubits that perform imperfect operations. The goal of NISQ algorithms is to leverage the limited available resources to perform classically challenging tasks, paving the way towards the long-awaited Fault-Tolerant quantum computation while seeking short and medium-term applications. NISQ algorithms present several challenges, both from experimental and theoretical points of view. We will review some of these challenges and learn the basics and applications of one of the leading representatives of NISQ: the Variational Quantum Algorithms.

Seminario: Quantum Computing and High Energy Physics
Ponente: Miriam Lucio Martinez, University of Maastricht
Fecha: 04/05/2023
Abstract: Quantum Computing constitutes a very promising field, potentially able to deal with challenges that classic computing cannot solve and present considerable speedups with respect to the former.

Its application to fields related to fundamental physics seems as a natural extension of its use-cases, due to the underlying quantum nature of the processes involved and the type of the problems that particle physics experiments entail. This talk will cover some of the most important lines of research that have so far been pursued in this regard, with the current status and prospects, including the NISQ era.

Seminario: Exploring applications of variational quantum algorithms in linear algebra
Ponente: Carlos Bravo, investigador postdoctoral de la Universidad Libre de Berlín (Freie Universität Berlin).
Fecha: 10/03/2023
Abstract: Quantum computing is a rapidly developing field that holds great promise for solving complex problems.

However, current quantum computers have limitations, such as a limited number of qubits and susceptibility to errors. To overcome these limitations, Variational Quantum Algorithms (VQAs) have emerged as a promising approach. In this talk, we will explore some of the applications of VQAs. We will discuss the basics of VQAs and provide examples of their use in solving linear algebra problems.

Seminario: Quantum machine learning algorithms and its implementation in molecular qudits
Ponente: Sebastián Roca-Jerat, Investigador INMA – CSIC – Universidad de Zaragoza
Fecha: 25/01/2023
Abstract: Quantum machine learning (QML) is recently gaining interest in both theory and experiment thanks to variational circuits implemented in the noisy intermediate-scale quantum computers (NISQs).

Since we are in such an era, algorithms capable of being implemented in small circuits are of great interest. In pursuit of this objective, we explore QML algorithms that are implementable in circuits involving a single qudit, a system with d 2 levels, instead of the traditional qubit (d = 2). Molecules with large electronic and/or nuclear spins provide a natural platform with multiple operational levels, being a suitable choice for implementing our qudits. Operations are driven by electromagnetic pulses resonant with the allowed transitions, which can be realized with EPR techniques or by coupling them to superconducting circuits. It has been shown that this type of control in a single qudit is sufficient to implement any d-dimensional unitary operation, thus being an universal quantum processing unit. Specifically, we explore supervised learning and classification problems of databases comprising more classes than levels are accessible in our qudit, forcing the development of tools to find maximally orthogonal states.

Seminario: Architecting full stack quantum computing systems in the NISQ era and beyond
Ponente: Carmen G. Almudever, distinguida investigadora de la Universidad Politécnica de Valencia.
Fecha: 18/11/2022
Abstract: The advances in quantum hardware with functional quantum processors integrating tens of noisy qubits, together with the availability of near-term quantum algorithms have allowed the development of the so-called full-stacks that bridge quantum applications with quantum devices.

In this talk, we will provide an overview of the different layers of the quantum computing full-stack, with emphasis on the software ones that include the compilation of quantum algorithms. We will then discuss the need for optimal physical-aware and algorithm-driven compilation techniques in the midst of the NISQ (Noisy Intermediate-scale quantum) era. We will also focus on key principles for architecting quantum computers such as codesign, optimization and benchmarking and illustrate how the use of structured design space exploration methodologies could help towards the development of a cross-layer codesign framework for full-stack quantum computing systems. Finally, we will talk about the scalability of quantum computing systems, which is one of the main challenges the quantum computing community is currently facing.

Seminario: Beyond-classical computation from a computer science perspective
Ponente: Sergio Boixo, director científico de Quantum Computer Theory en el Quantum Artificial Intelligence Lab de Google
Fecha: 20/06/2022
Abstract: Outperforming classical supercomputers in a well-defined computational task is an important milestone in the long term quest for practical quantum computing.

I will argue that this milestone has been reached for the task of random quantum circuit sampling. I will review recent advances in complexity theory and classical algorithms related to this experiment. BosonSampling is another important proposal for early beyond-classical demonstrations. I will review recent BosonSampling experiments and algorithms.
