Quantum Simulators: Architectures and Opportunities
Ehud Altman, Kenneth R. Brown, Giuseppe Carleo +34
Quantum simulators are a promising technology on the spectrum of quantum devices from specialized quantum experiments to universal quantum computers. These quantum devices utilize…
Motional Quantum Ground State of a Levitated Nanoparticle from Room Temperature
Uroš Delić, Manuel Reisenbauer, Kahan Dare +4
We report quantum ground state cooling of a levitated nanoparticle in a room temperature environment. Using coherent scattering into an optical cavity we cool the center of mass mo…
Heralded Interaction Control between Quantum Systems
Yiheng Duan, Mahdi Hosseini, Kristin M. Beck +1
Quantum mechanical expectation values for subsets can differ substantially from those for the whole ensemble. This implies that the effect of interactions between two systems can b…
Strong coupling of two individually controlled atoms via a nanophotonic cavity
Polnop Samutpraphoot, Tamara Ðorđević, Paloma L. Ocola +4
We demonstrate photon-mediated interactions between two individually trapped atoms coupled to a nanophotonic cavity. Specifically, we observe superradiant line broadening when the…
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…
Strongly Correlated Quantum Gas Prepared by Direct Laser Cooling
Pablo Solano, Yiheng Duan, Yu-Ting Chen +3
We create a one-dimensional strongly correlated quantum gas of Cs atoms with attractive interactions by direct laser cooling in 300~ms. After compressing and cooling the op…
