Optimised Bayesian system identification in quantum devices
Thomas M. Stace, Jiayin Chen, Li Li +6
Identifying and calibrating quantitative dynamical models for physical quantum systems is important for a variety of applications. Here we present a closed-loop Bayesian learning a…
Quantum oscillator noise spectroscopy via displaced cat states
Alistair R. Milne, Cornelius Hempel, Li Li +5
Quantum harmonic oscillators are central to many modern quantum technologies. We introduce a method to determine the frequency noise spectrum of oscillator modes through coupling t…
Investigating Quantum Approximate Optimization Algorithms under Bang-bang Protocols
Daniel Liang, Li Li, Stefan Leichenauer
The quantum approximate optimization algorithm (QAOA) is widely seen as a possible usage of noisy intermediate-scale quantum (NISQ) devices. We analyze the algorithm as a bang-bang…
Eternal non-Markovianity is generic for the spin-boson model
Li Li, Michael J. W. Hall
The spin-boson model describes a qubit coupled to a bosonic bath in thermal equilibrium, and is applicable to a wide range of physical contexts. We show that two weak conditions fo…
Exact Non-Markovian master equation for the Spin-Boson and Jaynes-Cummings models
L. Ferialdi
We provide the exact non-Markovian master equation for a two-level system interacting with a thermal bosonic bath, and we write the solution of such a master equation in terms of t…
