Nonlocal Games as Cross-Platform Quantum Benchmarks: Exceeding unconditional classical bounds on trapped-ion processors
Anton T. Than, Jim Furches, Debopriyo Biswas +15
Nonlocal games provide application-level benchmarks for quantum hardware whose classical performance bounds are information-theoretic, holding against all classical strategies rega…
Excitonic Quantum Anomalous Hall Effect in Collinear Magnets Without Spin-Orbit Coupling
Xingxing Liu, ChaoYang Tan, Peng-Jie Guo +2
Spin-orbit coupling (SOC) is thought to be necessary in realizing quantum anomalous Hall (QAH) insulators in magnetic materials. In this Letter, we propose an exciton-condensation…
The phase diagram of quantum chromodynamics in one dimension on a quantum computer
Anton T. Than, Yasar Y. Atas, Abhijit Chakraborty +8
The quantum chromodynamics (QCD) phase diagram, which reveals the state of strongly interacting matter at different temperatures and densities, is key to answering open questions i…
Observation of quantum-field-theory dynamics on a spin-phonon quantum computer
Anton T. Than, Saurabh V. Kadam, Vinay Vikramaditya +5
Simulating out-of-equilibrium dynamics of quantum field theories in nature is challenging with classical methods, but is a promising application for quantum computers. Unfortunatel…
Benchmarking a Tunable Quantum Neural Network on Trapped-Ion and Superconducting Hardware
Djamil Lakhdar-Hamina, Xingxin Liu, Richard Barney +4
We implement a quantum generalization of a neural network on trapped-ion and IBM superconducting quantum computers to classify MNIST images, a common benchmark in computer vision.…
Featuremetric benchmarking: Quantum computer benchmarks based on circuit features
Timothy Proctor, Anh Tran, Xingxin Liu +4
Benchmarks that concisely summarize the performance of many-qubit quantum computers are essential for measuring progress towards the goal of useful quantum computation. In this wor…
