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…
Two-mode squeezing and SU(1,1) interferometry with trapped ions
J. Metzner, A. Quinn, S. Brudney +4
We experimentally implement circuits of one and two mode operations on two motional modes of a single trapped ion. This is achieved by implementing the required displacement, squee…
State Readout of a Trapped Ion Qubit Using a Trap-Integrated Superconducting Photon Detector
S. L. Todaro, V. B. Verma, K. C. McCormick +7
We report high-fidelity state readout of a trapped ion qubit using a trap-integrated photon detector. We determine the hyperfine qubit state of a single Be ion held in a su…
