Benchmarking exchange-only control of a 48-spin singlet manifold
HRL Quantum Team, Microsoft Collaborators, : +125
Exchange-only quantum computing benefits from high fidelity and straightforward control afforded by the exchange interaction. However, independently controllable qubits must be enc…
A digitally controlled silicon quantum processing unit
Members of the HRL Quantum Team, Collaborators, : +255
Commercially-relevant quantum computers will require large numbers of high-performing qubits that can be manufactured, integrated, and controlled at scale. Silicon exchange-only (E…
MagAO-X: Commissioning Results and Status of Ongoing Upgrades
Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +20
MagAO-X is the coronagraphic extreme adaptive optics system for the 6.5 m Magellan Clay Telescope. We report the results of commissioning the first phase of MagAO-X. Components now…
Characterizing the Dark Count Rate of a Large-Format MKID Array
Noah Swimmer, W. Hawkins Clay, Nicholas Zobrist +1
We present an empirical measurement of the dark count rate seen in a large-format MKID array identical to those currently in use at observatories such as Subaru on Maunakea. This w…
Probing Photon Statistics in Adaptive Optics Images with SCExAO/MEC
Sarah Steiger, Timothy D. Brandt, Olivier Guyon +11
We present an experimental study of photon statistics for high-contrast imaging with the Microwave Kinetic Inductance Detector (MKID) Exoplanet Camera (MEC) located behind the Suba…
SCExAO and Keck Direct Imaging Discovery of a Low-Mass Companion Around the Accelerating F5 Star HIP 5319
Noah Swimmer, Thayne Currie, Sarah Steiger +26
We present the direct imaging discovery of a low-mass companion to the nearby accelerating F star, HIP 5319, using SCExAO coupled with the CHARIS, VAMPIRES, and MEC instruments in…
Membrane-less phonon trapping and resolution enhancement in optical microwave kinetic inductance detectors
Nicholas Zobrist, W. Hawkins Clay, Grégoire Coiffard +4
Microwave Kinetic Inductance Detectors (MKIDs) sensitive to light in the ultraviolet to near-infrared wavelengths are superconducting micro-resonators that are capable of measuring…
The MKID Science Data Pipeline
