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…
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…
Atomic Fock State Preparation Using Rydberg Blockade
Matthew Ebert, Alexander Gill, Michael Gibbons +3
We use coherent excitation of 3-16 atom ensembles to demonstrate collective Rabi flopping mediated by Rydberg blockade. Using calibrated atom number measurements, we quantitatively…
