| Abstract: |
I'll first briefly discuss a new, simple Lindblad master equation that handles weakly damped systems for all detunings between transitions. This fills the gap between the degenerate and non-degenerae master equations. Most of the talk will be devoted to a recent circuit that uses bulk Chi-2 nonlinearities to perform quantum error correction for photon loss using a two-mode bosonic code.
The talk is based on: Accurate Lindblad-form master equation for weakly damped quantum systems across all regimes G McCauley, B Cruikshank, DI Bondar, K Jacobs npj Quantum Information 6 (1), 1-14 Room-Temperature Photonic Logical Qubits via Second-Order Nonlinearities S Krastanov, M Heuck, JH Shapiro, P Narang, DR Englund, K Jacobs arXiv preprint arXiv:2002.07193 |
