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…
Active protection of a superconducting qubit with an interferometric Josephson isolator
Baleegh Abdo, Nicholas T. Bronn, Oblesh Jinka +8
Nonreciprocal microwave devices play several critical roles in high-fidelity, quantum-nondemolition (QND) measurement schemes. They separate input from output, impose unidirectiona…
Multi-Path Interferometric Josephson Directional Amplifier for Qubit Readout
Baleegh Abdo, Nick Bronn, Oblesh Jinka +3
We realize and characterize a quantum-limited, directional Josephson amplifier suitable for qubit readout. The device consists of two nondegenerate, three-wave-mixing amplifiers th…
High Coherence Plane Breaking Packaging for Superconducting Qubits
Nicholas T. Bronn, Vivekananda P. Adiga, Salvatore B. Olivadese +3
We demonstrate a pogo pin package for a superconducting quantum processor specifically designed with a nontrivial layout topology (e.g., a center qubit that cannot be accessed from…
