Programmable generation of flying cat-qubits
Cecilia Erneman, Zeidan Zeidan, Göran Johansson +1
We propose a framework for the direct generation of flying cat-qubit states from vacuum using time-dependent two-photon drives in nonlinear bosonic systems. We study both Kerr-base…

Successive quasienergy collapse and breakdown of photon blockade in the few-emitter limit
T. Karmstrand, G. Johansson, R. Gutiérrez-Jáuregui
The emergent behavior that arises in many-body systems of increasing size follows universal laws that become apparent in order-to-disorder transitions. While this behavior has been…
