Ultrafast all-optical switching by single photons
Thomas Volz, Andreas Reinhard, Martin Winger +4
An outstanding goal in quantum optics is the realization of fast optical non-linearities at the single-photon level. Such non-linearities would allow for the realization of optical…
Modified coherence of quantum spins in a damped pure-dephasing model
Mattias T. Johnsson, Ben Q. Baragiola, Thomas Volz +1
We consider a spin- particle coupled to a structured bath of bosonic modes that decay into thermal baths. We obtain an analytic expression for the reduced spin state and use it…
Absorptive laser threshold magnetometry: combining visible diamond Raman lasers and nitrogen-vacancy centres
Sarath Raman Nair, Lachlan J. Rogers, David J. Spence +5
We propose a high-sensitivity magnetometry scheme based on a diamond Raman laser with visible pump absorption by an ensemble of coherently microwave driven negatively charged nitro…
Roadmap for Optical Tweezers
Giovanni Volpe, Onofrio M. Maragò, Halina Rubinzstein-Dunlop +80
Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation of objects ranging from atoms to space light sails. Since the pioneering work b…
Strongly correlated photons on a chip
Andreas Reinhard, Thomas Volz, Martin Winger +4
Optical non-linearities at the single-photon level are key ingredients for future photonic quantum technologies. Prime candidates for the realization of strong photon-photon intera…
Efficient fiber-pigtailed source of indistinguishable single photons
Nico Margaria, Florian Pastier, Thinhinane Bennour +19
Semiconductor quantum dots in microcavities are an excellent platform for the efficient generation of indistinguishable single photons. However, their use in a wide range of quantu…
