Project Description

Quantum photonics provides a promising route towards quantum communication, computing, and simulation. A quantum photonic system must consist of sources, tunable photonic elements, detectors, nonlinear elements, and memories. However, combining these into a scalable system has not been possible because of incompatibility of materials and devices. We recently took a first step towards solving that problem by using a home-built nanomanipulator to integrate 128 diamond single-photon sources onto a photonic circuit [1]. We want now to build on this method to make it more efficient [2] and applicable to all the key modules. Such a system can enable millions of qubits for quantum communication and high-fidelity optical quantum logic gates for quantum computing, and ultimately bring quantum technologies closer to applications. This UROP project will cover a part of the abovementioned project, depending on the skills and interests of the applicant. These parts can be, but are not limited to: 1) improving our setup for efficient transfer, 2) designing building blocks, and 3) device characterization. [1] N. H.
