High-frequency nonlinear conductivity of a Wigner crystal
A. J. Schleusner, M. T. Elewa, N. R. Beysengulov +2
Electrons trapped above the surface of superfluid helium are a disorder-free platform for investigating the formation and dynamics of low-dimensional Wigner crystals. A characteris…
20 Second Parity Lifetime in an InAs--Pb Tetron Device
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162
A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…
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…
Plasmon Mode Engineering with Electrons on Helium
C. A. Mikolas, N. R. Beysengulov, A. J. Schleusner +3
An ensemble of electrons trapped above superfluid helium offers a paradigm system for investigating and controlling collective charge dynamics in low-dimensional electronic matter.…
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…
Evidence for nitrogen gas surface doping of the BiSe topological insulator
Michael Gottschalk, Mal-Soon Lee, Eric Goodwin +6
Using scanning tunneling spectroscopy we have studied the effects of nitrogen gas exposure on the bismuth selenide density of states. We observe a shift in the Dirac point which is…
