New geometries and materials are to be proposed and studied. SSPD based on photonic crystal coherent absorbers have shown great strength in detecting single photons in communication wavelength but remains challenging for midIR. A single photon detection system with near unity quantum efficiency, low dark count and bandwidth is essential to realize QI systems.

All these directions will more or less involve: theoretical study of condensed matter, quantum/nonlinear optical, or QI systems numerical simulation and design with commercial software such as Lumerical FDTD and COMSOL experimental study of photonic systems and light-matter interaction and fun. With a goal to realize a silicon photonics QI platform with donor spin qubits, this project involves a few inherently connected directions.

Particularly, by implanting 77Se + ions into silicon photonic crystal cavities with high quality factors (Q) and small mode volumes would enable coupling and readout of qubits with a spin-photon interface in midIR wavelength range under the strong-coupling regime. Compared to the group V hydrogenic donors such as phosphorus, the deep chalcogen donors (sulfur, selenium and tellurium) offer significantly larger electron binding energy, especially when singly ionized, which makes them suitable for optical control through cavity quantum electrodynamics. However, a robust and scalable QI system is yet to be demonstrated on these qubits. The remarkable coherence and control characteristics of donor spin qubits in silicon, with their intrinsic CMOS compatibility, make them ideal qubits for QI applications, even when compared with NV centers in diamond and quantum dots.
