Journal ArticleDOI
Measuring entanglement entropy in a quantum many-body system
Rajibul Islam,Ruichao Ma,Philipp M. Preiss,M. Eric Tai,Alexander Lukin,Matthew Rispoli,Markus Greiner +6 more
TL;DR: Making use of the single-site-resolved control of ultracold bosonic atoms in optical lattices, two identical copies of a many-body state are prepared and interfered to directly measure quantum purity, Rényi entanglement entropy, and mutual information.
Journal ArticleDOI
Quantum simulation of frustrated Ising spins with trapped ions
Kihwan Kim,Ming-Shien Chang,S. Korenblit,Rajibul Islam,E.E. Edwards,James Freericks,Guin-Dar Lin,Luming Duan,Christopher Monroe +8 more
TL;DR: In this paper, a quantum simulation of a frustrated spin system is described, in which there are three trapped atomic ions whose interactions are controlled using optical forces, and the ground state of this system is analyzed.
Journal ArticleDOI
Emergence and frustration of magnetism with variable-range interactions in a quantum simulator.
Rajibul Islam,Crystal Senko,Wesley C. Campbell,S. Korenblit,J. Smith,A. Lee,E.E. Edwards,C.-C. Wang,James Freericks,Christopher Monroe +9 more
TL;DR: This prototypical quantum simulation points the way toward a new probe of frustrated quantum magnetism and perhaps the design of new quantum materials.
Journal ArticleDOI
Programmable quantum simulations of spin systems with trapped ions
Christopher Monroe,Wesley C. Campbell,Luming Duan,Zhe-Xuan Gong,Alexey V. Gorshkov,Paul Hess,Rajibul Islam,Kihwan Kim,Norbert M. Linke,Guido Pagano,Philip Richerme,Crystal Senko,Norman Y. Yao +12 more
TL;DR: Monroe et al. as discussed by the authors used a laser-cooled and trapped atomic ions for the simulation of interacting quantum spin models, where effective spins are represented by appropriate internal energy levels within each ion, and the spins can be measured with near-perfect efficiency using state-dependent fluorescence techniques.
Journal ArticleDOI
Strongly correlated quantum walks in optical lattices
Philipp M. Preiss,Ruichao Ma,M. Eric Tai,Alexander Lukin,Matthew Rispoli,Philip Zupancic,Yoav Lahini,Rajibul Islam,Markus Greiner +8 more
TL;DR: Using interacting bosonic atoms in an optical lattice, this work directly observed fundamental effects such as the emergence of correlations in two-particle quantum walks, as well as strongly correlated Bloch oscillations in tilted optical lattices.
