Non-destructive selective probing of phononic excitations in a cold Bose gas using impurities
D. Hangleiter, M. T. Mitchison, T. H. Johnson +3
We introduce a detector that selectively probes the phononic excitations of a cold Bose gas. The detector is composed of a single impurity atom confined by a double-well potential,…
Capturing exponential variance using polynomial resources: applying tensor networks to non-equilibrium stochastic processes
T. H. Johnson, T. J. Elliott, S. R. Clark +1
Estimating the expected value of an observable appearing in a non-equilibrium stochastic process usually involves sampling. If the observable's variance is high, many samples are r…
What is a quantum simulator?
T. H. Johnson, S. R. Clark, D. Jaksch
Quantum simulators are devices that actively use quantum effects to answer questions about model systems and, through them, real systems. Here we expand on this definition by answe…
Chiral Quantum Walks
DaWei Lu, Jacob D. Biamonte, Jun Li +8
Given its importance to many other areas of physics, from condensed matter physics to thermodynamics, time-reversal symmetry has had relatively little influence on quantum informat…
