Feedback Cooling and Thermometry of a Single Trapped Ion Using a Knife Edge
Hans Dang, Sebastian Luff, Martin Fischer +2
We report on a simple and easy to implement method of feedback cooling trapped ions to temperatures below those achievable using only Doppler cooling. Additionally, the feedback co…
Quantum-dot single photon source performance with off-resonant pulse preparation schemes
Gavin Crowder, Lora Ramunno, Stephen Hughes
The preparation of photonic qubits in the excited state is an integral part of the performance of an on-demand single photon source (SPS). Conventional resonant excitation, an exce…
Erbium-Doped Fibre Quantum Memory for Chip-Integrated Quantum-Dot Single Photons at 980 nm
Nasser Gohari Kamel, Arsalan Mansourzadeh, Ujjwal Gautam +8
The realization of long-distance quantum communication and the envisioned quantum internet relies on coherent hybrid light-matter interfaces connecting quantum light emitters with…
Violation of local realism with spatially multimode parametric down-conversion pumped by spatially incoherent light
Cheng Li, Jeremy Upham, Boris Braverman +1
We experimentally demonstrate a violation of local realism with highly spatially multimode polarization-entangled two-photon states produced by spontaneous parametric down-conversi…
Reinforcement Learning for Optimal Control of Spin Magnetometers
Logan W. Cooke, Stefanie Czischek
Quantum optimal control in the presence of decoherence is difficult, particularly when not all Hamiltonian parameters are known precisely, as in quantum sensing applications. In th…
High-Dimensional Quantum Key Distribution with Qubit-like States
Lukas Scarfe, Rojan Abolhassani, Frédéric Bouchard +4
Quantum key distribution (QKD) protocols most often use two conjugate bases in order to verify the security of the quantum channel. In the majority of protocols, these bases are mu…
