Laser

A high-performance, pulsed resonant excitation laser is required to drive Sparrow Core at 80 ± 0.5 MHz; supports lower rates via an external pulse picker (<80 MHz) with dedicated optical in/out.

Electrical module

Industrial-grade computer and control electronics handle automated startup, alignment, calibration, and continuous monitoring for closed-loop thermal/optical stability. Runs as an unattended service and interacts through a served web app or automated with the API.

Cryostat

We recommend a compact cryostat to house the Sparrow Core; compressor is placed in an adjacent rack for vibration suppression, supporting stable long-run operation.

Optical module

Precision free-space optics with integrated sensors, camera, and motorized mechanics for stable photon extraction and fiber coupling; single-photon output on PM fiber (PM780, FC/APC) with options (PM980/custom).

Sparrow Core

InAs-based quantum dot chip providing world-class single-photon metrics (indistinguishability 90–97%, g(2)(0) < 1%, fiber efficiency 30–50%), with fixed per-chip wavelength typically 920–960 nm. Learn more about Sparrow Core.

Built for seamless deployment in labs and supercomputing centers.

Sparrow Nest is built for advanced labs and HPC sites, and ships as a fully self-contained system in a standard 19-inch rack. It runs on standard power and integrates all subsystems in-rack for quick deployment and reliable day-to-day operation.
