Exact collective occupancies of the Moshinsky model in two-dimensional geometry
We consider a system of N bosons in a two-dimensional isotropic harmonic potential, interacting with a force proportional…

Deterministic generation of two-dimensional multi-photon cluster states
Device architecture and cluster state generation protocol To generate ladder-like cluster states, we use two transmon qubits whose…
Spin-qubit control with a milli-kelvin CMOS chip
To evaluate single-qubit gates, we first establish a baseline using all room-temperature electronics for control. Following the usual…
