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…
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…
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…
