Benchmarking Quantum Processor Performance at Scale
June 8, 2024 | Luke Govia
As quantum processors enter the era of utility, it becomes increasingly important to develop benchmarking suites capable of addressing quality, speed, and scale. With scale increasing rapidly for utility, quality benchmarks are needed that can be run at large scales. In this talk, we review the status of benchmarking quantum processors, and report recent developments towards benchmarks that can operator a 100+ qubit scale.

Toward Quantum Computation of Quantum Field Theories
October 7, 2021 | Yuta Kikuchi, Brookhaven National Lab
C2QA Quantum Thursdays: Classical computations of quantum field theories (QFTs) typically suffer from prohibitively large degrees of freedom that scales exponentially with their system size. Although the Monte Carlo method is a well-established approach to circumvent the issue in many cases, real-time evolution of physical systems, quantum chromodynamics (QCD) at finite chemical potential, and so on, are notable examples that the Monte Carlo method fails to simulate. Quantum computing, on the other hand, is expected to be capable of accommodating such a large number of degrees of freedom, as well as, efficiently carrying out computations by exploiting quantum nature of devices such as superposition of states and quantum entanglement.
