Quantifying error and leakage in an encoded Si/SiGe triple-dot qubit
R. W. Andrews, C. Jones, M. D. Reed +13
Quantum computation requires qubits that satisfy often-conflicting criteria, including scalable control and long-lasting coherence. One approach to creating a suitable qubit is to…
Spin-Blockade Spectroscopy of Si/SiGe Quantum Dots
A. M. Jones, E. J. Pritchett, E. H. Chen +15
We implement a technique for measuring the singlet-triplet energy splitting responsible for spin-to-charge conversion in semiconductor quantum dots. This method, which requires fas…
Diamond optomechanical crystals
Michael J. Burek, Justin D. Cohen, Seán M. Meenehan +11
Cavity-optomechanical systems realized in single-crystal diamond are poised to benefit from its extraordinary material properties, including low mechanical dissipation and a wide o…
Pulsed excitation dynamics of an optomechanical crystal resonator near its quantum ground-state of motion
Sean M. Meenehan, Justin D. Cohen, Gregory S. MacCabe +3
Using pulsed optical excitation and read-out along with single phonon counting techniques, we measure the transient back-action, heating, and damping dynamics of a nanoscale silico…
Phonon counting and intensity interferometry of a nanomechanical resonator
Justin D. Cohen, Sean M. Meenehan, Gregory S. MacCabe +5
Using an optical probe along with single photon detection we have performed effective phonon counting measurements of the acoustic emission and absorption processes in a nanomechan…
Thermalization properties at mK temperatures of a nanoscale optomechanical resonator with acoustic-bandgap shield
Sean M. Meenehan, Justin D. Cohen, Simon Groeblacher +4
Optical measurements of a nanoscale silicon optomechanical crystal cavity with a mechanical resonance frequency of 3.6GHz are performed at sub-kelvin temperatures. We infer optical…
