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 phases of Rydberg atoms on a kagome lattice
Rhine Samajdar, Wen Wei Ho, Hannes Pichler +2
We analyze the zero-temperature phases of an array of neutral atoms on the kagome lattice, interacting via laser excitation to atomic Rydberg states. Density-matrix renormalization…
High-Fidelity Entanglement and Detection of Alkaline-Earth Rydberg Atoms
Ivaylo S. Madjarov, Jacob P. Covey, Adam L. Shaw +7
Trapped neutral atoms have become a prominent platform for quantum science, where entanglement fidelity records have been set using highly-excited Rydberg states. However, controll…
Complex density wave orders and quantum phase transitions in a model of square-lattice Rydberg atom arrays
Rhine Samajdar, Wen Wei Ho, Hannes Pichler +2
We describe the zero-temperature phase diagram of a model of a two-dimensional square-lattice array of neutral atoms, excited into Rydberg states and interacting via strong van der…
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…
