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

该联盟负责开发具有高收集效率的偏振纠缠光子的确定性固态源，用于量子通信和信息处理。它将利用单个偶极子（单个原子....）每个激发周期只发射一个光子对的事实。所研究的发射器将是单个量子点，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通过控制纳米结构生长，应用磁场或电场或使用腔效应来擦除。将量子点插入适当的微谐振腔中，以便有效地收集发射的光子对。高收集效率加上发射的确定性将导致量子通信非常有用的源。该项目汇集了在该领域已经取得重大突破的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.
