Dispersive optical systems for scalable Raman driving of hyperfine qubits
Harry Levine, Dolev Bluvstein, Alexander Keesling +7
Hyperfine atomic states are among the most promising candidates for qubit encoding in quantum information processing. In atomic systems, hyperfine transitions are typically driven…
Probing Topological Spin Liquids on a Programmable Quantum Simulator
Giulia Semeghini, Harry Levine, Alexander Keesling +13
Quantum spin liquids, exotic phases of matter with topological order, have been a major focus of explorations in physical science for the past several decades. Such phases feature…
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…
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,…
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…
High-fidelity control and entanglement of Rydberg atom qubits
Harry Levine, Alexander Keesling, Ahmed Omran +7
Individual neutral atoms excited to Rydberg states are a promising platform for quantum simulation and quantum information processing. However, experimental progress to date has be…
Probing many-body dynamics on a 51-atom quantum simulator
Hannes Bernien, Sylvain Schwartz, Alexander Keesling +9
Controllable, coherent many-body systems can provide insights into the fundamental properties of quantum matter, enable the realization of new quantum phases and could ultimately l…
