Autonomous quantum error correction of Gottesman-Kitaev-Preskill states
Dany Lachance-Quirion, Marc-Antoine Lemonde, Jean Olivier Simoneau +12
The Gottesman-Kitaev-Preskill (GKP) code encodes a logical qubit into a bosonic system with resilience against single-photon loss, the predominant error in most bosonic systems. He…
Protecting backaction-evading measurements from parametric instability
E. P. Ruddy, Y. Jiang, N. E. Frattini +2
Noiseless measurement of a single quadrature in systems of parametrically coupled oscillators is theoretically possible by pumping at the sum and difference frequencies of the two…
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…
