Quantum theory of a three-photon Kerr parametric oscillator
Alessandro Bruno, Patrick P. Potts, Alexander Grimm +1
We investigate the quantum properties of a nonlinear Kerr oscillator driven by a three-photon pump. We derive both exact and approximate analytical expressions for the ground state…

Enhancing Kerr-Cat Qubit Coherence with Controlled Dissipation
Francesco Adinolfi, Daniel Z. Haxell, Alessandro Bruno +4
Quantum computing crucially relies on maintaining quantum coherence for the duration of a calculation. Bosonic quantum error correction protects this coherence by encoding qubits i…
