ERA NANOSCI: Deterministic single quantum dot Nano-sources of Entangled Photons paiRs

该联盟致力于开发用于量子通信和信息处理的高收集效率的确定性固态偏振纠缠光子源。它将利用单个偶极(单个原子……)的事实。每个激发周期只发射一个光子对。所研究的发射体将是单个量子点，通过控制纳米结构的生长、施加磁场或电场或利用空腔效应，通常在量子点中观察到的发射光子的能量中包含的路径信息将被擦除。量子点将被插入适当的微谐振器中，以便有效地收集发射的光子对。高收集效率和辐射的确定性性质将导致量子通信的高度有用的来源。该项目汇集了在该领域已经取得重大突破、具有独特经验的合作伙伴。

The Consortium undertakes the development of deterministic solid-state source of polarization entangled photons with a high collection efficiency, for quantum communications and information processing. It will make use of the fact that a single dipole (a single atom....) emits only one photon pair per excitation cycle. The emitter under study will be a single quantum dot The which path information contained in the energy of the emitted photons usually observed in quantum dots, will be erased by control of the nanostructure growth, application of a magnetic or electric field, or use of cavity effect. Quantum dots will be inserted in appropriate microresonators in order to efficiently collect the emitted photon pairs. High collection efficiencies together with the deterministic nature of the emission will result in a highly useful source for quantum communications. The project brings together partners with unique experience who have already achieved major breakthroughs in this field.
