Engineering magnetically insensitive qubits in metastable electronic D-states of trapped ions
Ksenia Sosnova, Martin Lichtman, Allison Carter +2
Ion trap quantum computers often store qubits on field-sensitive S_1/2 ground state Zeeman levels of the valence electron, such as in 40Ca+, 88Sr+, and 138Ba+ atomic systems. We ex…
Demonstration of a Logical Architecture Uniting Motion and In-Place Entanglement
Rich Rines, Benjamin Hall, Mariesa H. Teo +35
We demonstrate a logical neutral atom architecture that integrates atom motion with in-place entanglement to achieve lower overheads than entangling-zone approaches. Using a 114-qu…
Fault-Tolerant Operation and Materials Science with Neutral Atom Logical Qubits
Matt. J. Bedalov, Matt Blakely, Peter. D. Buttler +27
We report on the fault-tolerant operation of logical qubits on a neutral atom quantum computer, with logical performance surpassing physical performance for multiple circuits inclu…
Interleaved dual-species arrays of single atoms using a passive optical element and one trapping laser
Chengyu Fang, Jared Miles, Jonathan Goldwin +8
We demonstrate trapping of individual rubidium (Rb) and cesium (Cs) atoms in an interleaved array of bright tweezers and dark bottle-beam traps, using a microfabricated optical ele…
A universal neutral-atom quantum computer with individual optical addressing and non-destructive readout
A. G. Radnaev, W. C. Chung, D. C. Cole +55
Quantum computers must achieve large-scale, fault-tolerant operation to deliver on their promise of transformational processing power [1-4]. This will require thousands or millions…
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…
High Purity Single Photons Entangled with an Atomic Memory
Clayton Crocker, Martin Lichtman, Ksenia Sosnova +3
Trapped atomic ions are an ideal candidate for quantum network nodes, with long-lived identical qubit memories that can be locally entangled through their Coulomb interaction and r…
Quantum repeaters based on two species trapped ions
Siddhartha Santra, Sreraman Muralidharan, Martin Lichtman +3
We examine the viability of quantum repeaters based on two-species trapped ion modules for long distance quantum key distribution. Repeater nodes comprised of ion-trap modules of c…
Multi-Species Trapped Ion Node for Quantum Networking
I. V. Inlek, C. Crocker, M. Lichtman +2
Trapped atomic ions are a leading platform for quantum information networks, with long-lived identical qubit memories that can be locally entangled through their Coulomb interactio…
A Rydberg blockade CNOT gate and entanglement in a 2D array of neutral atom qubits
K. M. Maller, M. T. Lichtman, T. Xia +5
We present experimental results on two-qubit Rydberg blockade quantum gates and entanglement in a two-dimensional qubit array. Without post selection against atom loss we achieve a…
Randomized benchmarking of single qubit gates in a 2D array of neutral atom qubits
T. Xia, M. Lichtman, K. Maller +4
We characterize single qubit Clifford gate operations with randomized benchmarking in a 2D array of neutral atom qubits, and demonstrate global and site selected gates with high fi…
A two-dimensional lattice of blue detuned atom traps using a projected Gaussian beam array
M. J. Piotrowicz, M. Lichtman, K. Maller +4
We describe a new type of blue detuned optical lattice for atom trapping which is intrinsically two dimensional, while providing three-dimensional atom localization. The lattice is…
