Probing Qubit Memory Errors at the Part-per-Million Level
M. A. Sepiol, A. C. Hughes, J. E. Tarlton +7
Robust qubit memory is essential for quantum computing, both for near-term devices operating without error correction, and for the long-term goal of a fault-tolerant processor. We…
The effect of atomic response time in the theory of Doppler cooling of trapped ions
H. Janacek, A. M. Steane, D. M. Lucas +1
We describe a simple approach to the problem of incorporating the response time of an atom or ion being Doppler-cooled into the theory of the cooling process. The system being cool…
High-fidelity spatial and polarization addressing of Ca-43 qubits using near-field microwave control
D. P. L. Aude Craik, N. M. Linke, M. A. Sepiol +7
Individual addressing of qubits is essential for scalable quantum computation. Spatial addressing allows unlimited numbers of qubits to share the same frequency, whilst enabling ar…
Dark-resonance Doppler cooling and high fluorescence in trapped Ca-43 ions at intermediate magnetic field
D. T. C. Allcock, T. P. Harty, M. A. Sepiol +5
We demonstrate simple and robust methods for Doppler cooling and obtaining high fluorescence from trapped 43Ca+ ions at a magnetic field of 146 Gauss. This field gives access to a…
Hybrid quantum logic and a test of Bell's inequality using two different atomic isotopes
C. J. Ballance, V. M. Schaefer, J. P. Home +9
Entanglement is one of the most fundamental properties of quantum mechanics, and is the key resource for quantum information processing. Bipartite entangled states of identical par…
Microwave control electrodes for scalable, parallel, single-qubit operations in a surface-electrode ion trap
D. P. L. Aude Craik, N. M. Linke, T. P. Harty +4
We propose a surface ion trap design incorporating microwave control electrodes for near-field single-qubit control. The electrodes are arranged so as to provide arbitrary frequenc…
