Benchmarking an 11-qubit quantum computer

K. Wright, K. M. Beck, S. Debnath +21

The field of quantum computing has grown from concept to demonstration devices over the past 20 years. Universal quantum computing offers efficiency in approaching problems of scie…

Demonstration of two-atom entanglement with ultrafast optical pulses

J. D. Wong-Campos, S. A. Moses, K. G. Johnson +1

We demonstrate quantum entanglement of two trapped atomic ion qubits using a sequence of ultrafast laser pulses. Unlike previous demonstrations of entanglement mediated by the Coul…

Ultrafast Creation of Large Schrödinger Cat States of an Atom

K. G. Johnson, J. D. Wong-Campos, B. Neyenhuis +2

Mesoscopic quantum superpositions, or Schrödinger cat states, are widely studied for fundamental investigations of quantum measurement and decoherence as well as applications in se…

Active Stabilization of Ion Trap Radiofrequency Potentials

K. G. Johnson, J. D. Wong-Campos, A. Restelli +4

We actively stabilize the harmonic oscillation frequency of a laser-cooled atomic ion confined in a rf Paul trap by sampling and rectifying the high voltage rf applied to the trap…

High resolution adaptive imaging of a single atom

J. D. Wong-Campos, K. G. Johnson, B. Neyenhuis +2

We report the optical imaging of a single atom with nanometer resolution using an adaptive optical alignment technique that is applicable to general optical microscopy. By decompos…

Sensing Atomic Motion from the Zero Point to Room Temperature with Ultrafast Atom Interferometry

K. G. Johnson, B. Neyenhuis, J. Mizrahi +2

We sense the motion of a trapped atomic ion using a sequence of state-dependent ultrafast momentum kicks. We use this atom interferometer to characterize a nearly-pure quantum stat…
