Multipartite entanglement in a Josephson Junction Laser

Ben Lang, Andrew D. Armour

We analyse the entanglement in a model Josephson photonics system in which a dc voltage-biased Josephson junction couples a collection of cavity modes and populates them with micro…

Discrete time translation symmetry breaking in a Josephson junction laser

Ben Lang, Grace F. Morley, Andrew D. Armour

A Josephson junction laser is realised when a microwave cavity is driven by a voltage-biased Josephson junction. Through the ac Josephson effect, a dc voltage generates a periodic…

Defining the semiclassical limit of the quantum Rabi Hamiltonian

E. K. Twyeffort Irish, A. D. Armour

The crossover from quantum to semiclassical behavior in the seminal Rabi model of light-matter interaction still, surprisingly, lacks a complete and rigorous understanding. A forma…

Josephson Photonics with Simultaneous Resonances

Kieran Wood, Andrew D. Armour, Ben Lang

Inelastic Cooper pair tunneling across a voltage-biased Josephson junction in series with one or more microwave cavities can generate photons via resonant processes in which the en…

A macroscopic object passively cooled into its quantum ground state of motion: beyond single-mode cooling

D. Cattiaux, I. Golokolenov, S. Kumar +8

The building blocks of Nature, namely atoms and elementary particles, are described by quantum mechanics. This fundamental theory is the ground on which physicists have built their…

Multi-Photon Resonances in Josephson Junction-Cavity Circuits

Ben Lang, Andrew D. Armour

We explore the dissipative dynamics of nonlinearly driven oscillator systems tuned to resonances where multiple excitations are generated. Such systems are readily realised in circ…
