Universal Control in Bosonic Systems with Weak Kerr Nonlinearities
Ming Yuan, Alireza Seif, Andrew Lingenfelter +3
Resonators with weak single-photon self-Kerr nonlinearities can theoretically be used to prepare Fock states in the presence of a loss much larger than their nonlinearities. Two ne…
Broadband Bandpass Purcell Filter for Circuit Quantum Electrodynamics
Haoxiong Yan, Xuntao Wu, Andrew Lingenfelter +10
In circuit quantum electrodynamics (QED), qubits are typically measured using dispersively-coupled readout resonators. Coupling between each readout resonator and its electrical en…
Exact Results for a Boundary-Driven Double Spin Chain and Resource-Efficient Remote Entanglement Stabilization
Andrew Lingenfelter, Mingxing Yao, Andrew Pocklington +4
We derive an exact solution for the steady state of a setup where two -coupled -qubit spin chains (with possibly non-uniform couplings) are subject to boundary Rabi drives,…
Fully Directional Quantum-limited Phase-Preserving Amplifier
Gangqiang Liu, Andrew Lingenfelter, Vidul R. Joshi +4
We present a way to achieve fully directional, quantum-limited phase-preserving amplification in a four-port, four-mode superconducting Josephson circuit by utilizing interference…
