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…
Quantifying and controlling prethermal nonergodicity in interacting Floquet matter
Kevin Singh, Cora J. Fujiwara, Zachary A. Geiger +10
The use of periodic driving for synthesizing many-body quantum states depends crucially on the existence of a prethermal regime, which exhibits drive-tunable properties while fores…
Transport in Floquet-Bloch bands
C. J. Fujiwara, Kevin Singh, Zachary A. Geiger +4
We report Floquet band engineering of long-range transport and direct imaging of Floquet-Bloch bands in an amplitude-modulated optical lattice. In one variety of Floquet-Bloch band…
Observation and uses of position-space Bloch oscillations in an ultracold gas
Zachary A. Geiger, Kurt M. Fujiwara, Kevin Singh +8
We report the direct observation and characterization of position-space Bloch oscillations using an ultracold gas in a tilted optical lattice. While Bloch oscillations in momentum…
Experimental Realization of a Relativistic Harmonic Oscillator
Kurt M. Fujiwara, Zachary A. Geiger, Kevin Singh +5
We report the experimental study of a harmonic oscillator in the relativistic regime. The oscillator is composed of Bose-condensed lithium atoms in the third band of an optical lat…
Quantum Simulation of Ultrafast Dynamics Using Trapped Ultracold Atoms
Ruwan Senaratne, Shankari V. Rajagopal, Toshihiko Shimasaki +5
Ultrafast electronic dynamics are typically studied using pulsed lasers. We demonstrate a complementary experimental approach: quantum simulation of ultrafast dynamics using trappe…
Effusive Atomic Oven Nozzle Design Using an Aligned Microcapillary Array
Ruwan Senaratne, Shankari V. Rajagopal, Zachary A. Geiger +3
We present a simple and inexpensive design for a multichannel effusive oven nozzle which provides improved atomic beam collimation and thus extended oven lifetimes. Using this desi…
