Long-lived memory effects in the defect bath of superconducting qubits

Abhishek Agarwal, Masum Uddin, Shroya Vaidya +5

We reveal long-lived memory effects in the defect bath of a superconducting transmon qubit through electric-field tuning of two-level system (TLS) defects coupled to the qubit. Usi…

In-operando microwave scattering-parameter calibrated measurement of a Josephson travelling wave parametric amplifier

S. H. Shin, M. Stanley, W. N. Wong +5

Superconducting travelling wave parametric amplifiers (TWPAs) are broadband near-quantum limited microwave amplifiers commonly used for qubit readout and a wide range of other appl…

Coherent spin dynamics of rare-earth doped crystals in the high-cooperativity regime

Joseph Alexander, Gavin Dold, Oscar W. Kennedy +9

Rare-earth doped crystals have long coherence times and the potential to provide quantum interfaces between microwave and optical photons. Such applications benefit from a high coo…

Spin echo silencing using a current-biased frequency-tunable resonator

V. Ranjan, Y. Wen, A. K. V. Keyser +5

The ability to control microwave emission from a spin ensemble is a requirement of several quantum memory protocols. Here, we demonstrate such ability by using a resonator whose fr…
