Journal ArticleDOI
Engineered two-dimensional Ising interactions in a trapped-ion quantum simulator with hundreds of spins
Joseph W. Britton,Brian C. Sawyer,Adam C. Keith,Adam C. Keith,C.-C. Joseph Wang,James Freericks,Hermann Uys,Michael J. Biercuk,John J. Bollinger +8 more
TL;DR: A spin-dependent optical dipole force can produce an antiferromagnetic interaction, and this demonstration, coupled with the high spin count, excellent quantum control and low technical complexity of the Penning trap, brings within reach the simulation of otherwise computationally intractable problems in quantum magnetism.
Journal ArticleDOI
Optimized dynamical decoupling in a model quantum memory
Michael J. Biercuk,Hermann Uys,Hermann Uys,Aaron P. VanDevender,Nobuyasu Shiga,Wayne M. Itano,John J. Bollinger +6 more
TL;DR: In this paper, an analytically derived pulse sequence, UDD, was used to demonstrate massive suppression of qubit error rates by the application of optimized dynamical decoupling pulse sequences, using a model quantum system capable of simulating a variety of quantum technologies.
Journal ArticleDOI
Toward scalable ion traps for quantum information processing
J. M. Amini,Hermann Uys,J. H. Wesenberg,S. Seidelin,Joseph W. Britton,John J. Bollinger,D. Leibfried,Christian Ospelkaus,Aaron P. VanDevender,David J. Wineland +9 more
TL;DR: In this paper, a 150 zone ion trap array built in a'surface-electrode' geometry micro- fabricated on a single substrate is presented. But the design of the trap is not described.
Journal ArticleDOI
Ultrasensitive detection of force and displacement using trapped ions
Michael J. Biercuk,Michael J. Biercuk,Hermann Uys,Hermann Uys,Joseph W. Britton,Aaron P. VanDevender,John J. Bollinger +6 more
TL;DR: It is demonstrated that crystals of trapped atomic ions behave as nanoscale mechanical oscillators and may form the core of exquisitely sensitive force and displacement detectors and enable scientists to explore new regimes in materials science where augmented force, field and displacement sensitivity may be traded against reduced spatial resolution.
Journal ArticleDOI
Optomechanical trapping and cooling of partially reflective mirrors
TL;DR: In this article, the authors considered the radiative trapping and cooling of a partially reflecting mirror suspended inside an optical cavity, generalizing the case of a perfectly reflecting mirror previously considered, and proposed a bichromatic scheme that optimizes the cooling and trapping of partially reflective mirrors.
