Josephson directional amplifier for quantum measurement of superconducting circuits
Baleegh Abdo, Katrina Sliwa, S. Shankar +4
We have realized a microwave quantum-limited amplifier that is directional and can therefore function without the front circulator needed in many quantum measurements. The amplific…
Stabilizing entanglement autonomously between two superconducting qubits
S. Shankar, M. Hatridge, Z. Leghtas +7
Quantum error-correction codes would protect an arbitrary state of a multi-qubit register against decoherence-induced errors, but their implementation is an outstanding challenge f…
Three-wave mixing with three incoming waves: Signal-Idler Coherent Cancellation and Gain Enhancement in a Parametric Amplifier
Flavius Schackert, Ananda Roy, Michael Hatridge +2
Coherent, purely-dispersive three-wave mixing systems in optics and superconducting microwave circuits can be operated as parametric amplifiers, generating from a pump wave at one…
