Performance Stabilization of High-Coherence Superconducting Qubits
Andrew Dane, Karthik Balakrishnan, Brent Wacaser +7
Superconducting qubits have been used in the most advanced demonstrations of quantum information processing, and they can be manufactured at-scale using proven semiconductor techni…
Merged-Element Transmons: Design and Qubit Performance
H. J. Mamin, E. Huang, S. Carnevale +12
We have demonstrated a novel type of superconducting transmon qubit in which a Josephson junction has been engineered to act as its own parallel shunt capacitor. This merged-elemen…
Decoherence of near-surface nitrogen-vacancy centers due to electric field noise
M. Kim, H. J. Mamin, M. H. Sherwood +3
We show that electric field noise from surface charge fluctuations can be a significant source of spin decoherence for near-surface nitrogen-vacancy (NV) centers in diamond. This c…
Spurious harmonic response of multipulse quantum sensing sequences
M. Loretz, J. M. Boss, T. Rosskopf +3
Multipulse sequences based on Carr-Purcell decoupling are frequently used for narrow-band signal detection in single spin magnetometry. We have analyzed the behavior of multipulse…
Multipulse Double-Quantum Magnetometry With Near-Surface Nitrogen Vacancy Centers
H. J. Mamin, M. H. Sherwood, M. Kim +4
We discuss multipulse magnetometry that exploits all three magnetic sublevels of the S=1 nitrogen-vacancy center in diamond to achieve enhanced magnetic field sensitivity. Based on…
Detecting External Electron Spins Using Nitrogen-Vacancy Centers
H. J. Mamin, M. H. Sherwood, D. Rugar
Near-surface nitrogen-vacancy (NV) centers have been created in diamond through low energy implantation of 15N to sense electron spins that are external to the diamond. By performi…
