Quantum routing of single optical photons with a superconducting flux qubit

2018 · Physical Review A

Interconnecting optical photons with superconducting circuits is a challenging problem but essential for building long-range superconducting quantum networks. We propose a hybrid quantum interface between the microwave and optical domains where the propagation of a …

Strongly correlated quantum walks with a 12-qubit superconducting processor

2019 · Science

Quantum walks are the quantum analogs of classical random walks, which allow for the simulation of large-scale quantum many-body systems and the realization of universal quantum computation without time-dependent control. We experimentally demonstrate quantum walks …
