Benchmarking a trapped-ion quantum computer with 30 qubits
Jwo-Sy Chen, Erik Nielsen, Matthew Ebert +8
Quantum computers are rapidly becoming more capable, with dramatic increases in both qubit count and quality. Among different hardware approaches, trapped-ion quantum processors ar…
Demonstration of multi-qubit entanglement and algorithms on a programmable neutral atom quantum computer
T. M. Graham, Y. Song, J. Scott +22
Gate model quantum computers promise to solve currently intractable computational problems if they can be operated at scale with long coherence times and high fidelity logic. Neutr…
Generation of 14.0W of single frequency light at 770 nm by intracavity frequency doubling
Minho Kwon, Peiyu Yang, Preston Huft +3
We present a continuous, narrow-linewidth, tunable laser system that outputs up to 14.0 W at 770 nm. The light is generated by frequency doubling 18.8 W of light from a 1540 nm fib…
Rydberg mediated entanglement in a two-dimensional neutral atom qubit array
T. M. Graham, M. Kwon, B. Grinkemeyer +6
We demonstrate high fidelity two-qubit Rydberg blockade and entanglement in a two-dimensional qubit array. The qubit array is defined by a grid of blue detuned lines of light with…
Parallel low-loss measurement of multiple atomic qubits
Minho Kwon, Matthew F. Ebert, Thad G. Walker +1
We demonstrate low-loss measurement of the hyperfine ground state of Rubidium atoms in a dipole trap array of five sites by state dependent fluorescence detection. The presence of…
Coherence and Rydberg blockade of atomic ensemble qubits
M. Ebert, M. Kwon, T. G. Walker +1
We demonstrate state encoding of multi-atom ensemble qubits. Using optically trapped Rb atoms the coherence time is 2.6(3) ms for atoms and scales ap…
