MTL 2018 Fall Doctoral Dissertation Seminar (DDS) by Dr. Sara Mouradian

PhD thesis investigated photonic integrated circuits in diamond for quantum information processing
December 17, 2018

Engineered quantum systems promise advantages in sensing, communication, and computation over systems that can be described classically. In order to realize this quantum advantage, it is necessary to precisely build and control complex quantum systems. However, current experiments are limited by high decoherence rates, low entanglement rates, and large classical control overhead. 

In her talk titled "Scalable Solid State Quantum Information Processing," Dr. Sara Mouradian presented her research on increasing the scalability of quantum information processing with defect centers (negatively charged nitrogen vacancy centers) in diamond. The design and fabrication of high-quality nanophotonic resonators from a bulk diamond substrate allow for increased emission and collection of photons coherent with the spin state. In addition, the integration of diamond nodes into a photonic integrated circuit allows for low-loss collection, routing, and detection of photons from single defect centers. 

Mouradian conducted her Ph.D. under the supervision of Professor Dirk Englund in the department of Electrical Engineering and Computer Science at MIT. The work was performed in the Microsystems Technology Laboratories and the Research Laboratory of Electronics at MIT.
