Benchmarking verified logic operations for fault tolerance

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Akel Hashim, Stefan Seritan, Timothy Proctor, Kenneth Rudinger, Noah Goss | Summary: The promise of quantum computing depends upon the eventual achievement of fault-tolerant quantum error correction, which requires that the total rate of errors falls below some threshold. However, most contemporary methods for benchmarking noisy quantum […]

Benchmarking quantum logic operations for achieving fault tolerance

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Akel Hashim, Stefan Seritan, Timothy Proctor, Kenneth Rudinger, Noah Goss | Summary: Contemporary methods for benchmarking noisy quantum processors typically measure average error rates or process infidelities. However, thresholds for fault-tolerant quantum error correction are given in terms of worst-case error rates — defined via the diamond […]

Demonstrating scalable randomized benchmarking of universal gate sets

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Jordan Hines, Marie Lu, Ravi K. Naik, Akel Hashim, Jean-Loup Ville | Summary: Randomized benchmarking (RB) protocols are the most widely used methods for assessing the performance of quantum gates. However, the existing RB methods either do not scale to many qubits or cannot benchmark a universal […]

Adaptive Random Fourier Features Kernel LMS

Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Jie Chen, Cédric Richard, Wentao Shi, Qunfei Zhang | Summary: We propose the adaptive random Fourier features Gaussian kernel LMS (ARFF-GKLMS). Like most kernel adaptive filters based on stochastic gradient descent, this algorithm uses a preset number of random Fourier features to save computation cost. […]

Experimental Determination of a Single Atom Ground State Orbital through Hyperfine Anisotropy

Kavli Affiliate: Sander Otte | First 5 Authors: Laëtitia Farinacci, Lukas M. Veldman, Philip Willke, Sander Otte, | Summary: Historically, electron spin resonance (ESR) has provided excellent insight into the electronic, magnetic, and chemical structure of samples hosting spin centers. In particular, the hyperfine interaction between the electron and the nuclear spins yields valuable structural […]
