Two-dimensional Si spin qubit arrays with multilevel interconnects
Sieu D. Ha, Edwin Acuna, Kate Raach +26
The promise of quantum computation is contingent upon physical qubits with both low gate error rate and broad scalability. Silicon-based spins are a leading qubit platform, but dem…
Software systems for operation, control, and monitoring of the EBEX instrument
Michael Milligan, Peter Ade, François Aubin +35
We present the hardware and software systems implementing autonomous operation, distributed real-time monitoring, and control for the EBEX instrument. EBEX is a NASA-funded balloon…
The EBEX Balloon Borne Experiment - Optics, Receiver, and Polarimetry
The EBEX Collaboration, Asad M. Aboobaker, Peter Ade +35
The E and B Experiment (EBEX) was a long-duration balloon-borne cosmic microwave background polarimeter that flew over Antarctica in 2013. We describe the experiment's optical syst…
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…
The performance of the bolometer array and readout system during the 2012/2013 flight of the E and B experiment (EBEX)
Kevin MacDermid, Asad M. Aboobaker, Peter Ade +38
EBEX is a balloon-borne telescope designed to measure the polarization of the cosmic microwave background radiation. During its eleven day science flight in the Austral Summer of 2…
The EBEX Balloon-Borne Experiment - Gondola, Attitude Control, and Control Software
The EBEX Collaboration, Asad Aboobaker, Peter Ade +33
The E and B Experiment (EBEX) was a long-duration balloon-borne instrument designed to measure the polarization of the cosmic microwave background (CMB) radiation. EBEX was the fir…
Fast and high-fidelity state preparation and measurement in triple-quantum-dot spin qubits
Jacob Z. Blumoff, Andrew S. Pan, Tyler E. Keating +19
We demonstrate rapid, high-fidelity state preparation and measurement in exchange-only Si/SiGe triple-quantum-dot qubits. Fast measurement integration ( ns) and initialization…
EBEX: A balloon-borne CMB polarization experiment
Britt Reichborn-Kjennerud, Asad M. Aboobaker, Peter Ade +43
EBEX is a NASA-funded balloon-borne experiment designed to measure the polarization of the cosmic microwave background (CMB). Observations will be made using 1432 transition edge s…
The EBEX Cryostat and Supporting Electronics
Ilan Sagiv, Asad M. Aboobaker, Chaoyun Bao +41
We describe the cryostat and supporting electronics for the EBEX experiment. EBEX is a balloon-borne polarimeter designed to measure the B-mode polarization of the cosmic microwave…
Intensity-Coupled-Polarization in Instruments with a Continuously Rotating Half-Wave Plate
Joy Didier, Amber D. Miller, Derek Araujo +31
We discuss a systematic effect associated with measuring polarization with a continuously rotating half-wave plate. The effect was identified with the data from the E and B Experim…
The EBEX Balloon Borne Experiment - Detectors and Readout
The EBEX Collaboration, Maximilian Abitbol, Asad M. Aboobaker +37
EBEX was a long-duration balloon-borne experiment to measure the polarization of the cosmic microwave background. The experiment had three frequency bands centered at 150, 250, and…
Detuning Axis Pulsed Spectroscopy of Valley-Orbital States in Si/SiGe Quantum Dots
Edward H. Chen, Kate Raach, Andrew Pan +16
Silicon quantum dot qubits must contend with low-lying valley excited states which are sensitive functions of the quantum well heterostructure and disorder; quantifying and maximiz…
Temperature calibration of the E and B experiment
Francois Aubin, Asad M. Aboobaker, Peter Ade +40
The E and B Experiment (EBEX) is a balloon-borne polarimeter designed to measure the polarization of the cosmic microwave background radiation and to characterize the polarization…
