Superconducting quantum qubit and resonator are representative solid state quantum devices, which is also a good quantum system to simulate quantum phenomena in different fields such as quantum optics. A superconducting resonator with controlled mirror transparency was developed, leading to a variable coupling to the outside transmission line. The coupling can be adjusted through zero to a photon emission rate 1,000 times the intrinsic photon decay rate. Through a dynamic tuning of the coupling, we realize controlled catch and release of coherent state photons. Combined with a superconducting qubit, the system is also employed to release non-classical Fock state photons. In addition to an unprecedented control of the release time and release rate, we can further dynamically shape the waveform of released propagating photons. Our achievement may enable high-fidelity quantum state transfer between distant qubits, for which precisely-controlled waveform shaping is a critical and non-trivial requirement. |
