Noise Mitigation in Single Microwave Photon Counting by Cascaded Quantum Measurements
Alexandre S. May, Leo Sutevski, Jeanne Solard +7
While single-photon counting is routinely achieved in the optical domain, operational single microwave photon detectors (SMPDs) have only recently been demonstrated. SMPDs are crit…
Enhancing dissipative cat qubit protection by squeezing
Rémi Rousseau, Diego Ruiz, Emanuele Albertinale +38
Dissipative cat-qubits are a promising architecture for quantum processors due to their built-in quantum error correction. By leveraging two-photon stabilization, they achieve an e…
A cat qubit stabilization scheme using a voltage biased Josephson junction
Thiziri Aissaoui, Anil Murani, Raphaël Lescanne +1
DC-voltage-biased Josephson junctions have been recently employed in superconducting circuits for Hamiltonian engineering, demonstrating microwave amplification, single photon sour…
Observation of Josephson Harmonics in Tunnel Junctions
Dennis Willsch, Dennis Rieger, Patrick Winkel +27
Approaches to developing large-scale superconducting quantum processors must cope with the numerous microscopic degrees of freedom that are ubiquitous in solid-state devices. State…
