Quantum Sampling Algorithms, Phase Transitions, and Computational Complexity
Dominik S. Wild, Dries Sels, Hannes Pichler +2
Drawing independent samples from a probability distribution is an important computational problem with applications in Monte Carlo algorithms, machine learning, and statistical phy…
Quantum Phases of Matter on a 256-Atom Programmable Quantum Simulator
Sepehr Ebadi, Tout T. Wang, Harry Levine +12
Motivated by far-reaching applications ranging from quantum simulations of complex processes in physics and chemistry to quantum information processing, a broad effort is currently…
Quantum many-body scars from virtual entangled pairs
Sambuddha Chattopadhyay, Hannes Pichler, Mikhail D. Lukin +1
We study weak ergodicity breaking in a one-dimensional, nonintegrable spin-1 XY model. We construct for it an exact, highly excited eigenstate, which despite its large energy densi…
Parallel implementation of high-fidelity multi-qubit gates with neutral atoms
Harry Levine, Alexander Keesling, Giulia Semeghini +8
We report the implementation of universal two- and three-qubit entangling gates on neutral atom qubits encoded in long-lived hyperfine ground states. The gates are mediated by exci…
One-way quantum repeater based on near-deterministic photon-emitter interfaces
Johannes Borregaard, Hannes Pichler, Tim Schöder +3
We propose a novel one-way quantum repeater architecture based on photonic tree-cluster states. Encoding a qubit in a photonic tree-cluster protects the information from transmissi…
Emerging 2D Gauge theories in Rydberg configurable arrays
A. Celi, B. Vermersch, O. Viyuela +3
Solving strongly coupled gauge theories in two or three spatial dimensions is of fundamental importance in several areas of physics ranging from high-energy physics to condensed ma…
