Multipartite entanglement in a Josephson junction laser

B Lang, AD Armour - Physical Review A, 2024 - APS
We analyze 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 …

Discrete time translation symmetry breaking in a Josephson junction laser

B Lang, GF Morley, AD Armour - Physical Review B, 2023 - APS
A Josephson junction laser is realized when a microwave cavity is driven by a voltage-
biased Josephson junction. Through the ac Josephson effect, a dc voltage generates a …

The Non-linear Quantum Dynamics of Superconducting Circuitry

G Morley - eprints.nottingham.ac.uk
Over the last few decades, it has been established that the Josephson junction's (JJ) non-
linear nature can be used to manufacture novel quantum Hamiltonians. The uneven spacing …
