Giant polarization rotation induced by a single spin: A cavity-based spin-Photon interface
2015 Conference on Lasers and Electro-Optics (CLEO), 2015Co-Authors: Justin Demory, Mikhaïl Glazov, O. Krebs, Christophe Arnold, Aristide Lemaitre, Pascale Senellart, Pierre Voisin, Isabelle Sagnes, Loïc LancoAbstract:Entangling a single spin to the polarization of a single Incoming Photon, generated by an external source, would open new paradigms in quantum optics: this relies on the possibility that a single spin induces a macroscopic rotation of a Photon polarization. Up to now, however, the observed polarization rotations were limited to a few 10-3 degrees. Here we report the amplification by three orders of magnitude of the spin-Photon interaction, using a single hole spin in a quantum dot-pillar cavity system. A polarization rotation by ±6° is obtained when the spin is optically initialized in either the up or down state. We finally show how quantum measurements and quantum entanglement can be implemented with realistic cavity-QED devices.

Macroscopic rotation of Photon polarization induced by a single spin
Nature Communications, 2015Co-Authors: Christophe Arnold, Vivien Loo, Mikhaïl Glazov, O. Krebs, Aristide Lemaitre, Justin Demory, Pascale Senellart, Pierre Voisin, Isabelle Sagnes, Loïc LancoAbstract:Entangling a single spin to the polarization of a single Incoming Photon, generated by an external source, would open new paradigms in quantum optics such as delayed-Photon entanglement, deterministic logic gates or fault-tolerant quantum computing. These perspectives rely on the possibility that a single spin induces a macroscopic rotation of a Photon polarization. Such polarization rotations induced by single spins were recently observed, yet limited to a few 10(-3) degrees due to poor spin-Photon coupling. Here we report the enhancement by three orders of magnitude of the spin-Photon interaction, using a cavity quantum electrodynamics device. A single hole spin in a semiconductor quantum dot is deterministically coupled to a micropillar cavity. The cavity-enhanced coupling between the Incoming Photons and the solid-state spin results in a polarization rotation by ± 6° when the spin is optically initialized in the up or down state. These results open the way towards a spin-based quantum network.

Photoproduction of the f2′ (1525), a2(1320), and K2∗ (1430) PHOTOPRODUCTION of the f2′ (1525), ... JU-JUN XIE, E. OSET, and LI-SHENG GENG
Physical Review C, 2016Co-Authors: Ju-jun Xie, Eulogio Oset, Li Sheng GengAbstract:Assuming that the f2′(1525), a2(1320), and K2∗(1430) resonances are dynamically generated states from vector-meson-vector-meson interactions in the s-wave with spin S=2, we study the γp→f2′(1525)p, γp→a20(1320)p, and γp→K2∗(1430)Λ(Σ) reactions. These reactions proceed in the following way: the Incoming Photon first mutates into a ρ0, ω, or φ meson via vector-meson dominance, which then interacts with the ρ0, ω, or K∗ emitted by the Incoming proton to form the tensor mesons f2′(1525), a2(1320), and K2∗(1430). The picture is simple and has no free parameters, as all the parameters of the mechanism have been fixed in previous studies. We predict the differential and total cross sections of these reactions. The results can be tested in future experiments and therefore offer new clues about the nature of these tensor states. © 2016 American Physical Society.

ISSCC - Indirect X-ray Photon-counting image sensor with 27T pixel and 15e − rms accurate threshold
2011 IEEE International Solid-State Circuits Conference, 2011Co-Authors: Bart Dierickx, Benoit Dupont, Arnaud Defernez, Nayera AhmedAbstract:In X-ray imaging, as in other imaging domains, the ultimate sensitivity and signal-to-noise ratio are obtained when each Incoming Photon is counted — the so-called quantum limit. Present state-of-the-art digital radiography is largely “charge integration” based, which results in a read noise that is composed of the quantum-limited Photon shot noise, but also of electronic read noise and excess noise due to the non-reproducible charge packet sizes per absorbed X-ray Photon.
