Streaming quantum gate set tomography using the extended Kalman filter
J. P. Marceaux, Kevin Young
Closed-loop control algorithms for real-time calibration of quantum processors require efficient filters that can estimate physical error parameters based on streams of measured qu…
Experimental Characterization of Crosstalk Errors with Simultaneous Gate Set Tomography
Kenneth Rudinger, Craig W. Hogle, Ravi K. Naik +11
Crosstalk is a leading source of failure in multiqubit quantum information processors. It can arise from a wide range of disparate physical phenomena, and can introduce subtle corr…
Robustly decorrelating errors with mixed quantum gates
Anthony M. Polloreno, Kevin C. Young
Coherent errors in quantum operations are ubiquitous. Whether arising from spurious environmental couplings or errors in control fields, such errors can accumulate rapidly and degr…
Classifying single-qubit noise using machine learning
Travis L. Scholten, Yi-Kai Liu, Kevin Young +1
Quantum characterization, validation, and verification (QCVV) techniques are used to probe, characterize, diagnose, and detect errors in quantum information processors (QIPs). An i…
A volumetric framework for quantum computer benchmarks
Robin Blume-Kohout, Kevin C. Young
We propose a very large family of benchmarks for probing the performance of quantum computers. We call them volumetric benchmarks (VBs) because they generalize IBM's benchmark for…
Adiabatic quantum optimization with the wrong Hamiltonian
Kevin C. Young, Robin Blume-Kohout, Daniel A. Lidar
Analog models of quantum information processing, such as adiabatic quantum computation and analog quantum simulation, require the ability to subject a system to precisely specified…

Anand Ganti, Uzoma Onunkwo, Kevin Young
In this work, we introduce a new family of [[6k, 2k, 2]] codes designed specifically to be compatible with adiabatic quantum computation. These codes support computationally univer…
Error suppression and error correction in adiabatic quantum computation I: techniques and challenges
Kevin C. Young, Mohan Sarovar, Robin Blume-Kohout
Adiabatic quantum computation (AQC) is known to possess some intrinsic robustness, though it is likely that some form of error correction will be necessary for large scale computat…
Error suppression and error correction in adiabatic quantum computation II: non-equilibrium dynamics
Mohan Sarovar, Kevin C. Young
While adiabatic quantum computing (AQC) has some robustness to noise and decoherence it is widely believed that encoding, error suppression and error correction will be required to…
Converting a real quantum bath to an effective classical noise
Wayne M. Witzel, Kevin Young, Sankar Das Sarma
We present a cluster expansion method for approximating quantum spin-bath dynamics in terms of a classical Gaussian stochastic process. The cluster expansion produces the two-point…

Kevin C. Young, Matthew D. Grace
We present an approach to the simulation of quantum systems driven by classical stochastic processes that is based on the polynomial chaos expansion, a well-known technique in the…
Unification and limitations of error suppression techniques for adiabatic quantum computing
Kevin C. Young, Mohan Sarovar
While adiabatic quantum computation (AQC) possesses some intrinsic robustness to noise, it is expected that a form of error control will be necessary for large scale computations.…
