Decoherence of surface phonons in a quantum acoustic system
Camryn Undershute, Joseph M. Kitzman, Camille A. Mikolas +1
Phononic resonators are becoming increasingly important in quantum information science, both for applications in quantum computing, communication and sensing, as well as in experim…
Free-space coupling and characterization of transverse bulk phonon modes in lithium niobate in a quantum acoustic device
J. M. Kitzman, J. R. Lane, C. Undershute +5
Transverse bulk phonons in a multimode integrated quantum acoustic device are excited and characterized via their free-space coupling to a three-dimensional (3D) microwave cavity.…
Quantum acoustic Fano interference of surface phonons
J. M. Kitzman, J. R. Lane, C. Undershute +4
Quantum acoustic systems, which integrate surface or bulk phonons with superconducting qubits, offer a unique opportunity to investigate phononic and pr…
Phononic bath engineering of a superconducting qubit
J. M. Kitzman, J. R. Lane, C. Undershute +5
Phonons, the ubiquitous quanta of vibrational energy, play a vital role in the performance of quantum technologies. Conversely, unintended coupling to phonons degrades qubit perfor…
Helium surface fluctuations investigated with superconducting coplanar waveguide resonator
N. R. Beysengulov, C. A. Mikolas, J. M. Kitzman +6
Recent experiments on the coupling of the in-plane motional state of electrons floating on the surface of liquid helium to a microwave resonator have revealed the importance of hel…
Vantablack Shielding of Superconducting Qubit Systems
J. M. Kitzman, J. R. Lane, T. Stefanski +4
Circuit quantum electrodynamics (cQED) experiments on superconducting qubit systems typically employ radiation shields coated in photon absorbing materials to achieve high qubit co…
Noise performance & thermalization of single electron transistors using quantum fluids
N. R. Beysengulov, J. R. Lane, J. M. Kitzman +3
We report on low-temperature noise measurements of a single electron transistor (SET) immersed in superfluid He. The device acts as a charge sensitive electrometer able to dete…
