Chemical profiles of the oxides on tantalum in state of the art superconducting circuits
Russell A. McLellan, Aveek Dutta, Chenyu Zhou +23
Over the past decades, superconducting qubits have emerged as one of the leading hardware platforms for realizing a quantum processor. Consequently, researchers have made significa…
Disentangling Losses in Tantalum Superconducting Circuits
Kevin D. Crowley, Russell A. McLellan, Aveek Dutta +17
Superconducting qubits are a leading system for realizing large scale quantum processors, but overall gate fidelities suffer from coherence times limited by microwave dielectric lo…
Spin dynamics in quantum dots on liquid helium
M. I. Dykman, Ofek Asban, Qianfan Chen +2
Liquid He-4 is free from magnetic defects, making it an ideal substrate for electrons with long-lived spin states. Such states can serve as qubit states. Here we consider the spin…
Single Phonon Detection for Dark Matter via Quantum Evaporation and Sensing of Helium
S. A. Lyon, Kyle Castoria, Ethan Kleinbaum +4
Dark matter is five times more abundant than ordinary visible matter in our Universe. While laboratory searches hunting for dark matter have traditionally focused on the electrowea…
Narrow optical linewidths in erbium implanted in TiO
Christopher M. Phenicie, Paul Stevenson, Sacha Welinski +6
Atomic and atom-like defects in the solid-state are widely explored for quantum computers, networks and sensors. Rare earth ions are an attractive class of atomic defects that feat…
Electron Spin Resonance of P Donors in Isotopically Purified Si Detected by Contactless Photoconductivity
Philipp Ross, Brendon C. Rose, Cheuk C. Lo +4
Coherence times of electron spins bound to phosphorus donors have been measured, using a standard Hahn echo technique, to be up to 20 ms in isotopically pure silicon with [P]$ = 10…
