Inherent flux crosstalk and coupler-driven single-qubit gates in superconducting circuits
Balázs Gulácsi, Guido Burkard
Crosstalk refers to unwanted qubit addressing. This is particularly detrimental when scaling up quantum information systems because unintended interactions limit their overall perf…
Non-Markovianity induced by Pauli-twirling
Joris Kattemölle, Balázs Gulácsi, Guido Burkard
Noise forms a central obstacle to effective quantum information processing. Recent experimental advances have enabled the tailoring of noise properties through Pauli twirling, tran…
Universal dissipators for driven open quantum systems and the correction to linear response
Lorenzo Bernazzani, Balázs Gulácsi, Guido Burkard
We investigate in parallel two common pictures used to describe quantum systems interacting with their surrounding environment, i.e., the stochastic Hamiltonian description, where…
Revealing correlated noise with single-qubit operations
Balázs Gulácsi, Joris Kattemölle, Guido Burkard
Spatially correlated noise poses a significant challenge to fault-tolerant quantum computation by breaking the assumption of independent errors. Existing methods such as cycle benc…
Temporally correlated quantum noise in driven quantum systems
Balázs Gulácsi, Guido Burkard
The ubiquitous effects of the environment on quantum-mechanical systems generally cause temporally correlated fluctuations. This particularly holds for systems of interest for quan…
