  摘要:Superconducting circuits are demonstrated to be a very promising platform for constructing large scale quantum processor. Meanwhile, Josephson parametric amplifier (JPA) has become an important resource for superconducting quantum information experiments. We incorporated a JPA as a preamplifier in our setup for the readout of superconducting qubits. This led to drastic improvement in the signal to noise ratio and enabled us to achieve single-shot readout and observation of quantum jumps. Combining an artificial Λ-type three-level atom and single-shot readout technology, we demonstrated detection of a propagating microwave photon, which remains a challenging task due to its correspondingly small energy. In addition, I will introduce our recent development of JPA and SFQ electronics and discuss the potential applications to superconducting computing.
