Solid-state photonic quantum information processing is a promising alternative to bypass some of the limitations of superconducting transmon and trapped ion qubits. Photonic components fabricated on semiconductor chips have been extensively studied, including waveguides and optical resonators. Furthermore, on-chip quantum photonics can leverage mature nanofabrication techniques to scale large numbers of qubits. Notably, the matter-based qubits used in such photonic quantum systems can operate at 4 K, achievable with commercially available helium cryostats and eliminating bulky dilution refrigerators. Significant efforts focus on demonstrating on-chip photonic quantum computing, engineering on-demand single-photon emitters, and interfacing photons with matter-based qubits or quantum memories such as electron or hole spins. My project focuses on developing nanoscale photonic devices that deterministically integrate wavelength-tunable single-photon emitters based on InAs quantum dots with photonic device functionality. Specifically, I will present our strategy to overcome spatial and spectral inhomogeneity of InAs quantum dots and recent results on the fabrication of integrated nanophotonic devices.
