Mid-circuit ground-state cooling and ancilla readout in the architecture
Sean Brudney, Connor Burns, Gabriel J. Gregory +4
The trapped-ion optical-metastable-ground () architecture for quantum processors promises the full functionality of two-species experiments, including sympathetic coo…
Four- and six-photon stimulated Raman transitions for coherent qubit and qudit operations
Gabriel J. Gregory, Evan R. Ritchie, Alex Quinn +4
Quantum computers are typically composed of an array of two-level systems, or qubits, encoded in some information carrier, such as an electron, photon, or quantized circuit. The si…
Spontaneous Raman scattering out of a metastable atomic qubit
I. D. Moore, A. Quinn, J. O'Reilly +5
Metastable qubits in atomic systems can enable large-scale quantum computing by simplifying hardware requirements and adding efficient erasure conversion to the pre-existing toolbo…
High-fidelity entanglement of metastable trapped-ion qubits with integrated erasure conversion
A. Quinn, G. J. Gregory, I. D. Moore +6
Today's most advanced ion trap quantum computers have significant overhead due to the need for dual-species operation. Looking ahead, logical qubit register sizes will be limited b…
