An Efficient Optical Interface between Quantum Dots and Ultracold Atoms


"Quantum information science is a new branch of physics that promises to develop information technologies and measurement systems beyond the limits of classical physics. Physical implementations of quantum information schemes vary widely and include systems as disparate as superconducting circuits and trapped ions. While significant progress has been made in each platform, each has its own advantages and disadvantages. A new paradigm is emerging which aims to combine disparate systems to take advantage of each system's strengths while mitigating their weaknesses. An example of a hybrid quantum system could use single photons to efficiently transfer information and stationary systems (quantum memories) like atoms to store and manipulate it. Independently, semiconductor quantum dots have emerged as near-ideal sources of single photons while dense gases of neutral atoms have emerged as a leading candidate for quantum memories. As of yet, these leading technologies have not been integrated, a necessary step towards the development of a distributed quantum network. Here, we propose to develop an efficient atomic quantum memory specifically designed for use with a quantum dot single photon source. The experienced researcher, Matthew Rakher, has extensive experience developing quantum dot single photon sources as a graduate student and postdoc in the United States. The project manager, Philipp Treutlein, has many years of experience with ultracold atomic systems and in particular, the integration of atomic systems with solid-state systems. The inability to integrate quantum dots and neutral atoms to date is due to the fact that each system requires experimental expertise and a substantial knowledge base that do not strongly overlap. Given the unique combination of expertise described here, we believe that our proposal will yield significant results expediently and certainly meets the criteria and spirit of the Marie Curie Incoming International Fellowship program"
