Randomized benchmarking with non-Markovian noise and realistic finite-time gates
Antoine Brillant, Peter Groszkowski, Alireza Seif +2
We analyze the impact of non-Markovian classical noise on single-qubit randomized benchmarking experiments, in a manner that explicitly models the realization of each gate via real…
Squeezed superradiance enables robust entanglement-enhanced metrology even with highly imperfect readout
Martin Koppenhöfer, Peter Groszkowski, A. A. Clerk
Quantum metrology protocols using entangled states of large spin ensembles attempt to achieve measurement sensitivities surpassing the standard quantum limit (SQL), but in many cas…
Fast and Robust Geometric Two-Qubit Gates for Superconducting Qubits and beyond
F. Setiawan, Peter Groszkowski, Aashish A. Clerk
Quantum protocols based on adiabatic evolution are remarkably robust against imperfections of control pulses and system uncertainties. While adiabatic protocols have been successfu…
Simple master equations for describing driven systems subject to classical non-Markovian noise
Peter Groszkowski, Alireza Seif, Jens Koch +1
Driven quantum systems subject to non-Markovian noise are typically difficult to model even if the noise is classical. We present a systematic method based on generalized cumulant…
Dissipative superradiant spin amplifier for enhanced quantum sensing
Martin Koppenhöfer, Peter Groszkowski, Hoi-Kwan Lau +1
Quantum metrology protocols exploiting ensembles of two-level systems and Ramsey-style measurements are ubiquitous. However, in many cases excess readout noise severely degrade…
Scqubits: a Python package for superconducting qubits
Peter Groszkowski, Jens Koch
is an open-source Python package for simulating and analyzing superconducting circuits. It provides convenient routines to obtain energy spectra of common super…
