Observable Estimation in the Absence of Classical Verification
Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45
The predictive success of quantum mechanics underpins many areas of modern science, even as the exact simulation of large, interacting quantum systems remains beyond the reach of c…
Sampling hard circuits with verifiably high fidelity
Simon Martiel, Jay-U Chung, Alireza Seif +9
Sampling-based proposals are prominent candidates for demonstrating quantum computations beyond the reach of classical supercomputers. However, it has been difficult to combine the…
Benchmarking Quantum Processor Performance at Scale
David C. McKay, Ian Hincks, Emily J. Pritchett +3
As quantum processors grow, new performance benchmarks are required to capture the full quality of the devices at scale. While quantum volume is an excellent benchmark, it focuses…
The Error Reconstruction and Compiled Calibration of Quantum Computing Cycles
Arnaud Carignan-Dugas, Dar Dahlen, Ian Hincks +6
Quantum computers are inhibited by physical errors that occur during computation. For this reason, the development of increasingly sophisticated error characterization and error su…
Concepts and conditions for error suppression through randomized compiling
Adam Winick, Joel J. Wallman, Dar Dahlen +3
Randomized compiling reduces the effects of errors on quantum computers by tailoring arbitrary Markovian errors into stochastic Pauli noise. Here we prove that randomized compiling…
Leveraging Randomized Compiling for the QITE Algorithm
Jean-Loup Ville, Alexis Morvan, Akel Hashim +13
The success of the current generation of Noisy Intermediate-Scale Quantum (NISQ) hardware shows that quantum hardware may be able to tackle complex problems even without error corr…
Randomized compiling for scalable quantum computing on a noisy superconducting quantum processor
Akel Hashim, Ravi K. Naik, Alexis Morvan +11
The successful implementation of algorithms on quantum processors relies on the accurate control of quantum bits (qubits) to perform logic gate operations. In this era of noisy int…
Independent State and Measurement Characterization for Quantum Computers
Junan Lin, Joel J. Wallman, Ian Hincks +1
Correctly characterizing state preparation and measurement (SPAM) processes is a necessary step towards building reliable quantum processing units (QPUs). In this work, we discuss…
Statistical analysis of randomized benchmarking
Robin Harper, Ian Hincks, Chris Ferrie +2
Randomized benchmarking and variants thereof, which we collectively call RB+, are widely used to characterize the performance of quantum computers because they are simple, scalable…
Hamiltonian Learning with Online Bayesian Experiment Design in Practice
Ian Hincks, Thomas Alexander, Michal Kononenko +2
Estimating parameters of quantum systems is usually done by performing a sequence of predetermined experiments and post-processing the resulting data. It is known that online desig…
Methods for preparation and detection of neutron spin-orbit states
