Single-shot readout of multiple donor electron spins with a gate-based sensor

Mark R. Hogg, Prasanna Pakkiam, Samuel K. Gorman +5

Proposals for large-scale semiconductor spin-based quantum computers require high-fidelity single-shot qubit readout to perform error correction and read out qubit registers at the…

Characterization of a photon pair source based on a cold atomic ensemble using a cascade level scheme

Alessandro Cerè, Bharath Srivathsan, Gurpreet Kaur Gulati +2

We characterize a source of photon pairs based on cascade decay in a cold Rb-87 ensemble. This source is particularly suited to generate of photons for interaction with Rb-87 based…

Fiber cavities with integrated mode matching optics

Gurpreet Kaur Gulati, Hiroki Takahashi, Nina Podoliak +2

In fiber based Fabry-Pérot Cavities (FFPCs), limited spatial mode matching between the cavity mode and input/output modes has been the main hindrance for many applications. We have…

Optimised multi-ion cavity coupling

Stephen Begley, Markus Vogt, Gurpreet Kaur Gulati +2

Recent technological advances in cavity quantum electrodynamics (CQED) are paving the way to utilise multiple quantum emitters confined in a single optical cavity. In such systems…

Polarization entanglement and quantum beats of photon pairs from four-wave mixing in a cold Rb-87 ensemble

Gurpreet Kaur Gulati, Bharath Srivathsan, Brenda Chng +2

We characterize correlations in polarization and time of photon pairs generated from a cold cloud of Rb-87 atoms via a four-wave mixing process in a cascade level scheme. Quantum s…

Hong-Ou-Mandel interference between triggered and heralded single photons from separate atomic systems

Victor Leong, Sandoko Kosen, Bharath Srivathsan +3

We present Hong-Ou-Mandel interference of single photons generated via two different physical processes by two independent atomic systems: scattering by a single atom, and parametr…

Reversing the temporal envelope of a heralded single photon using a cavity

Bharath Srivathsan, Gurpreet Kaur Gulati, Alessandro Cerè +2

We demonstrate a way to prepare single photons with a temporal envelope that resembles the time reversal of photons from the spontaneous decay process. We use the photon pairs gene…

Counterintuitive temporal shape of single photons

Gurpreet Kaur Gulati, Bharath Srivathsan, Brenda Chng +3

We prepare heralded single photons from a photon pair source based on non-degenerate four-wave mixing in a cold atomic ensemble via a cascade decay scheme. Their statistics shows s…

Narrow Band Source of Transform-Limited Photon Pairs via Four-Wave Mixing in a Cold Atomic Ensemble

Bharath Srivathsan, Gurpreet Kaur Gulati, Chng Mei Yuen Brenda +3

We observe narrowband pairs of time-correlated photons of wavelengths 776\,nm and 795\,nm from non-degenerate four-wave mixing in a laser-cooled atomic ensemble of {Rb} usin…
