Enhancing qubit readout fidelity with two-mode squeezing of the coherent measurement signal
Baleegh Abdo, William Shanks, Oblesh Jinka +1
The ability to perform high-fidelity quantum nondemolition qubit readout is pivotal for the realization of large and powerful quantum computers. Such readout of superconducting qub…
Nondegenerate Josephson Mixers with Enhanced Bandwidth and Saturation Power for Quantum Signal Amplification and Transduction
Baleegh Abdo, Dongbing Shao, Shayne Cairns +6
Nondegenerate Josephson mixers (JMs), formed by coupling two different transmission-line resonators to Josephson ring modulators (JRMs), are vital and versatile devices capable of…
Teleportation and Entanglement Swapping of Continuous Quantum Variables of Microwave Radiation
Baleegh Abdo, William Shanks, Oblesh Jinka +2
Quantum communication is needed to build powerful quantum computers and establish reliable quantum networks. At its basis lies the ability to generate and distribute entanglement t…
Weakly Flux-Tunable Superconducting Qubit
José M. Chávez-Garcia, Firat Solgun, Jared B. Hertzberg +3
Flux-tunable qubits are a useful resource for superconducting quantum processors. They can be used to perform cPhase gates, facilitate fast reset protocols, avoid qubit-frequency c…
High-fidelity qubit readout using interferometric directional Josephson devices
Baleegh Abdo, Oblesh Jinka, Nicholas T. Bronn +2
Nonreciprocal microwave devices, such as circulators and isolators, are needed in high-fidelity qubit readout schemes to unidirectionally route the readout signals and protect the…
Quantum back-action of variable-strength measurement
M. Hatridge, S. Shankar, M. Mirrahimi +9
Measuring a quantum system can randomly perturb its state. The strength and nature of this back-action depends on the quantity which is measured. In a partial measurement performed…
