Experimental realization of deterministic and selective photon addition in a bosonic mode assisted by an ancillary qubit
Marina Kudra, Martin Jirlow, Mikael Kervinen +5
Bosonic quantum error correcting codes are primarily designed to protect against single-photon loss. To correct for this type of error, one can encode the logical qubit in code spa…

Modeling and Harmonic Balance Analysis of Parametric Amplifiers for Qubit Read-out
Daryoush Shiri, Hampus Renberg Nilsson, Pavan Telluri +4
Predicting the performance of traveling-wave parametric amplifiers (TWPAs) based on nonlinear elements like superconducting Josephson junctions (JJs) is vital for qubit read-out in…

Correlated frequency noise in a multimode acoustic resonator
Nuttamas Tubsrinuan, Jared H. Cole, Per Delsing +1
Frequency instabilities are a major source of errors in quantum devices. This study investigates frequency fluctuations in a surface acoustic wave (SAW) resonator, where reflection…
