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…
Controlling many-body dynamics with driven quantum scars in Rydberg atom arrays
Dolev Bluvstein, Ahmed Omran, Harry Levine +12
Controlling non-equilibrium quantum dynamics in many-body systems is an outstanding challenge as interactions typically lead to thermalization and a chaotic spreading throughout Hi…
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…
Generation and manipulation of Schrödinger cat states in Rydberg atom arrays
Ahmed Omran, Harry Levine, Alexander Keesling +16
Quantum entanglement involving coherent superpositions of macroscopically distinct states is among the most striking features of quantum theory, but its realization is challenging,…
Integrating Neural Networks with a Quantum Simulator for State Reconstruction
Giacomo Torlai, Brian Timar, Evert P. L. van Nieuwenburg +9
We demonstrate quantum many-body state reconstruction from experimental data generated by a programmable quantum simulator, by means of a neural network model incorporating known e…
Quantum Kibble-Zurek mechanism and critical dynamics on a programmable Rydberg simulator
Alexander Keesling, Ahmed Omran, Harry Levine +12
Quantum phase transitions (QPTs) involve transformations between different states of matter that are driven by quantum fluctuations. These fluctuations play a dominant role in the…
