Fast generation of Schrödinger cat states in a Kerr-tunable superconducting resonator
X. L. He, Yong Lu, D. Q. Bao +7
Schrödinger cat states, quantum superpositions of macroscopically distinct classical states, are an important resource for quantum communication, quantum metrology and quantum comp…
Single-flux-quantum-based Qubit Control with Tunable Driving Strength
Kuang Liu, Yifan Wang, Bo Ji +3
Single-flux-quantum (SFQ) circuits have great potential in building cryogenic quantum-classical interfaces for scaling up superconducting quantum processors. SFQ-based quantum gate…
Quasiparticle Dynamics in Superconducting Quantum-Classical Hybrid Circuits
Kuang Liu, Xiaoliang He, Zhengqi Niu +8
Single flux quantum (SFQ) circuitry is a promising candidate for a scalable and integratable cryogenic quantum control system. However, the operation of SFQ circuits introduces non…
Theory of microwave single-photon detection using an impedance-matched system
Kazuki Koshino, Kunihiro Inomata, Zhirong Lin +2
By properly driving a qubit-resonator system in the strong dispersive regime, we implement an "impedance-matched" system in the dressed states, where a resonant single photon d…
Josephson parametric phase-locked oscillator and its application to dispersive readout of superconducting qubits
Z. R. Lin, K. Inomata, K. Koshino +4
The parametric phase-locked oscillator (PPLO), also known as a parametron, is a resonant circuit in which one of the reactances is periodically modulated. It can detect, amplify, a…
Microwave Down-Conversion with an Impedance-Matched System in Driven Circuit QED
K. Inomata, K. Koshino, Z. R. Lin +4
By driving a dispersively coupled qubit-resonator system, we realize an "impedance-matched" system that has two identical radiative decay rates from the top level and interacts…
