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…

Continuously trapped matter-wave interferometry in magic Floquet-Bloch band structures

Xiao Chai, Eber Nolasco-Martinez, Xuanwei Liang +8

Trapped matter-wave interferometry offers the promise of compact high-precision local force sensing. However, noise in the trap itself can introduce new systematic errors which are…

Thermodynamic engine with a quantum degenerate working fluid

Ethan Q. Simmons, Roshan Sajjad, Kimberlee Keithley +6

Can quantum mechanical thermodynamic engines outperform their classical counterparts? To address one aspect of this question, we experimentally realize and characterize an isentrop…

Observation of the Quantum Boomerang Effect

Roshan Sajjad, Jeremy L. Tanlimco, Hector Mas +7

A particle in an Anderson-localized system, if launched in any direction, should on average return to its starting point and stay there. Despite the central role played by Anderson…

Interaction-driven breakdown of dynamical localization in a kicked quantum gas

Alec Cao, Roshan Sajjad, Hector Mas +7

Quantum interference can terminate energy growth in a continually kicked system, via a single-particle ergodicity-breaking mechanism known as dynamical localization. The effect of…

Transport controlled by Poincaré orbit topology in a driven inhomogeneous lattice gas

Alec Cao, Roshan Sajjad, Ethan Q. Simmons +3

In periodic quantum systems which are both homogeneously tilted and driven, the interplay between drive and Bloch oscillations controls transport dynamics. Using a quantum gas in a…

Non-exponential decay in Floquet-Bloch bands

Alec Cao, Cora J. Fujiwara, Roshan Sajjad +3

Exponential decay laws describe systems ranging from unstable nuclei to fluorescent molecules, in which the probability of jumping to a lower-energy state in any given time interva…
