Efficient operator method for modelling mode mixing in misaligned optical cavities
William J. Hughes, Thomas H. Doherty, Jacob A. Blackmore +2
The transverse field structure and diffraction loss of the resonant modes of Fabry-Pérot optical cavities are acutely sensitive to the alignment and shape of the mirror substrates.…
Mode mixing and losses in misaligned microcavities
William J. Hughes, Thomas H. Doherty, Jacob A. Blackmore +2
We present a study on the optical losses of Fabry-Pérot cavities subject to realistic transverse mirror misalignment. We consider mirrors of the two most prevalent surface forms: i…
Optimisation of Scalable Ion-Cavity Interfaces for Quantum Photonic Networks
Shaobo Gao, Jacob A. Blackmore, William J. Hughes +2
In the design optimisation of ion-cavity interfaces for quantum networking applications, difficulties occur due to the many competing figures of merit and highly interdependent des…
An optically-heated atomic source for compact ion trap vacuum systems
Shaobo Gao, William Hughes, David M. Lucas +2
We present a design for an atomic oven suitable for loading ion traps, which is operated via optical heating with a continuous-wave multimode diode laser. The absence of the low-re…
Effects of cavity birefringence in polarisation-encoded quantum networks
Ezra Kassa, William J Hughes, Shaobo Gao +1
The generation of entanglement between distant atoms via single photons is the basis for networked quantum computing, a promising route to large-scale trapped-ion and trapped-atom…
High-rate, high-fidelity entanglement of qubits across an elementary quantum network
L J Stephenson, D P Nadlinger, B C Nichol +7
We demonstrate remote entanglement of trapped-ion qubits via a quantum-optical fiber link with fidelity and rate approaching those of local operations. Two Sr qubi…
Sideband cooling of small ion Coulomb crystals in a Penning trap
G. Stutter, P. Hrmo, V. Jarlaud +3
We have recently demonstrated the laser cooling of a single Ca ion to the motional ground state in a Penning trap using the resolved-sideband cooling technique on the el…
Improving trapped-ion-qubit memories via code-mediated error-channel balancing
Yannick Seis, Benjamin J. Brown, Anders S. Sørensen +1
The high-fidelity storage of quantum information is crucial for quantum computation and communication. Many experimental platforms for these applications exhibit highly biased nois…
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…
Resolved-sideband laser cooling in a Penning trap
J. F. Goodwin, G. Stutter, R. C. Thompson +1
We report the laser cooling of a single ion in a Penning trap to the motional ground state in one dimension. Cooling is performed in the strong binding limit on…
Trapped-ion quantum error-correcting protocols using only global operations
Joseph F. Goodwin, Benjamin J. Brown, Graham Stutter +3
Quantum error-correcting codes are many-body entangled states that are prepared and measured using complex sequences of entangling operations. Each element of such an entangling se…
