A gauge-invariant theory of small Markovian errors in quantum gate sets
Juan Gonzalez De Mendoza, Corey Ostrove, Timothy Proctor +3
Noisy logic operations on a quantum computational register -- e.g., one or more qubits -- can be described by transfer matrices (a.k.a. CPTP maps or superoperators) that act linear…
The Road to Useful Quantum Computers
Timothy Proctor, Robin Blume-Kohout, Andrew Baczewski
Building a useful quantum computer is a grand science and engineering challenge, currently pursued intensely by teams around the world. In the 1980s, Richard Feynman and Yuri Manin…
Establishing trust in quantum computations
Timothy Proctor, Stefan Seritan, Erik Nielsen +4
Quantum computing hardware has grown sufficiently complex that it often can no longer be simulated by classical computers, but its computational power remains limited by errors. Th…
A Theory of Direct Randomized Benchmarking
Anthony M. Polloreno, Arnaud Carignan-Dugas, Jordan Hines +3
Randomized benchmarking (RB) protocols are widely used to measure an average error rate for a set of quantum logic gates. However, the standard version of RB is limited because it…
