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…
High-fidelity preparation, gates, memory and readout of a trapped-ion quantum bit
T. P. Harty, D. T. C. Allcock, C. J. Ballance +5
We implement all single-qubit operations with fidelities significantly above the minimum threshold required for fault-tolerant quantum computing, using a trapped-ion qubit stored i…
A microfabricated ion trap with integrated microwave circuitry
D. T. C. Allcock, T. P. Harty, C. J. Ballance +4
We describe the design, fabrication and testing of a surface-electrode ion trap, which incorporates microwave waveguides, resonators and coupling elements for the manipulation of t…
