I’m excited to announce the publication of our new research paper titled "Sb2S3/AlGaAs-based reconfigurable metasurface for dynamic polarization and directionality control of quantum emitter emission" in RSC Advances on September 16th, 2024. This paper, co-authored with my graduate student at the time, Md. Ehsanul Karim, introduces the first-ever phase change material (PCM)-based reconfigurable metasurfaces that dynamically control the polarization and directionality of quantum emitter (QE) emissions. These two factors are key to unlocking advancements in quantum computing, communication, and chiral optics. We utilized a novel hybrid plasmon-QE coupled system to achieve precise control over the amplitude and phase of scattered radiation. Our five metasurface designs offer high efficiency and groundbreaking control, setting the stage for high-speed quantum communication and dimensional quantum processing. Thrilled to contribute to the growing field of quantum photonics with this innovative research! #QuantumComputing #Photonics #QuantumOptics #Metasurfaces #RSCAdvances #QuantumResearch #Innovation #Science

MIT physicists have developed a new method that brings atoms closer together—down to just 50 nanometers apart. This close proximity greatly strengthens their magnetic interactions, opening up exciting possibilities for quantum research. By using lasers and cooling techniques with the element dysprosium, the team observed new behaviors like synchronized movements and heat transfer between atom layers. This advancement could lead to new quantum materials and technologies for quantum computing.

🎉 Congratulations to Marion Bassi for the successful defense of her PhD Thesis entitled "Tunable resilience to charge noise of a hole spin". The work was supervised by Xavier Jehl and Étienne Dumur. This PhD thesis explored the potential of spin qubits in group-IV semiconductor quantum dots for scalable quantum processors, focusing on hole particles due to their fast and all-electrical manipulation enabled by large spin-orbit coupling. Despite the challenge of environmental interactions degrading qubit coherence time, efforts have identified "sweetspots" of enhanced coherence dependent on magnetic field orientation. The research characterizes electrical noise impacts on a single hole spin qubit in a P-doped silicon-MOS structure, finding that these sweetspots form continuous "sweetlines" around magnetic field polar-angle components. Experimentally, sweetline operation demonstrates extended coherence times and efficient electric-dipole spin resonance with high Rabi frequencies and quality factors. The study highlights significant gate-voltage control of sweetlines, relevant for scalability, and extends the investigation to a two-qubit system, emphasizing the importance of tuning sweetlines in spin qubit systems. Thanks to Alexander Hamilton, Georgios Katsaros, Arne Laucht, David FERRAND, Maximilian Rimbach, and Hélène Béa for their participation to the jury. #phdthesis #quantum #quantumtechnologies #qubits CEA-Irig, Université Grenoble Alpes, Grenoble INP - UGA

Read the new paper by Alrik Durand, Yoann Baron, Félix Cache, Tobias Herzig, Mario KHOURY, Sebastien Pezzagna, Jan Meijer, Jean-Michel HARTMANN, Shay Reboh, Marco Abbarchi, Isabelle Robert-Philip, Jean-Michel Gérard, Vincent Jacques, Guillaume Cassabois, and Anaïs Dréau studying single 𝐺 centers in carbon-implanted silicon. 👉 https://lnkd.in/epAVaWxf Single color centers recently isolated in carbon-implanted silicon with an emission line at 1.28 𝜇m have so far been identified as a well-known defect called the 𝐺 center. In this paper, the authors demonstrate that these single defects are actually divided into two distinct families, each with specific single-photon properties. On one side are the genuine G centers, and on the other, the faux G centers, which belong to a different defect labeled the G⋆ center.  These results provide a safeguard against future defect misidentifications, which is crucial for the further development of quantum technologies relying on the quantum properties of G or G⋆ centers. This work is the result of a collaboration between the University of Montpellier, Leipzig University, IM2NP CNRS UMR 7334, CEA-Leti, SOLNIL, and the NPSC - Nanophysics and Semiconductors team of PHELIQS - Quantum Photonics, Electronics and Engineering. #researchpaper #quantumphotonics #photonics #nanotechnology #siliconphotonics CEA-Irig, Université Grenoble Alpes, Grenoble INP - UGA

An international team of researchers from Leibniz Universität Hannover (Germany) and the University of Strathclyde in Glasgow (United Kingdom) has disproved a previously held assumption about the impact of #multiphoton components in #interference effects of thermal fields (e.g. sunlight) and parametric single #photons (generated in non-linear crystals). The finding offers new starting points for research into photonic #quantum information systems. "We experimentally proved that the interference effect between thermal light and parametric single photons also leads to quantum interference with the background field. For this reason, the background cannot simply be neglected and subtracted from calculations, as has been the case up to now," says Prof. Dr. Michael Kues, Head of the Institute of Photonics and member of the Board of the PhoenixD Cluster of Excellence at Leibniz University Hannover.
