Dynamically suppressing cavity dephasing induced by frequency fluctuations of a coupled nonlinear mode
Yunwei Lu, Xinyuan You, Ziwen Huang +3
High-coherence superconducting cavities offer a promising platform for quantum information, with long coherence times and negligible intrinsic dephasing. However, cavity control ge…

Implementation of a quantum addressable router using superconducting qubits
Connie Miao, Sébastien Léger, Ziqian Li +3
The implementation of a quantum router capable of performing both quantum signal routing and quantum addressing (a Q2-router) represents a key step toward building quantum networks…

Direct detection of down-converted photons spontaneously produced at a single Josephson junction
Dorian Fraudet, Izak Snyman, Denis M. Basko +7
We study spontaneous photon decay into multiple photons triggered by strong non-linearities in a superconducting quantum simulator of the boundary sine-Gordon impurity model. Previ…
