Randomized benchmarking has emerged as a popular and easy-to-implement experimental technique for gauging the quality of gate operations in quantum computing devices. A typical randomized benchmarking procedure identifies the exponential decay in the fidelity as the benchmarking sequence of gates increases in length, and the decay rate is used to estimate the fidelity of the gate. That the fidelity decays exponentially, however, relies on the assumption of time-independent or static noise in…

Towards a general framework of Randomized Benchmarking for non-Markovian Noise

The rapid progress in the development of quantum devices is in large part due to the availability of a wide range of characterization techniques allowing to probe, test and adjust them. Nevertheless,

Estimation of correlations and nonseparability in quantum channels via unitarity benchmarking

TLDR
Sub-unitarity measures are introduced that are invariant under local changes of basis, generalize the unitarity of a channel, and allow for the analysis of quantum information exchange within channels and provide an information-disturbance relation.

Randomized Benchmarking for Non-Markovian Noise

TLDR
It is shown that one can identify non-Markovian features of the noise directly from the ASF through its deviations from the Markovian case, and a set of methods to collectively estimate these deviations, non- markovian memory time scales, and diagnose (in)coherence of non-markovian noise in an RB experiment are proposed.

Randomized Benchmarking, Correlated Noise, and Ising Models

TLDR
The expected randomized benchmarking sequence fidelity for a system subject to Gaussian time-correlated noise is computed and it is shown that the expected sequence fidelity is given by the partition function of a long-range coupled spin-one Ising model.

Theory of open quantum systems

A quantum dissipation theory is constructed with the system–bath interaction being treated rigorously at the second-order cumulant level for both reduced dynamics and initial canonical boundary

Dynamics of the dissipative two-state system

This paper presents the results of a functional-integral approach to the dynamics of a two-state system coupled to a dissipative environment. It is primarily an extended account of results obtained

On the exponential solution of differential equations for a linear operator

The present investigation was stimulated by a recent paper of K. 0. Friedrichs 113, who arrived at some purely algebraic problems in connection with the theory of linear operators in quantum

Complete Characterization of a Quantum Process: The Two-Bit Quantum Gate

We show how to fully characterize a quantum process in an open quantum system. We particularize the procedure to the case of a universal two-qubit gate in a quantum computer. We illustrate the method

Abstract We give an explicit way to experimentally determine the evolution operators which completely describe the dynamics of a quantum-mechanical black box: an arbitrary open quantum system. We
