The optical qubit generator efficient and deterministic
Electrically controlled photonic chip containing a set of integrated sources.
Fully deterministic Reliable Efficient Pure
The eDelight chip is installed in a low-vibration cryogenic system equipped with nanopositioners, for the active alignment of the single-photon sources. Laser excitation and single-photon collection is performed via one single-mode optical fiber placed right on top of the device at 4 Kelvin.
The installation of the optical fiber in the cryogenic system in possession by the customer is performed by Quandela’s engineers.
A micrometer-size single-photon source of eDelight is coupled and pigtailed to a single-mode fiber with high efficiency and long-term stability.
With this technique, the pigtailed eDelight chip can be installed in a standard cryogenic system, providing an “alignment free solution”: there is no need for nanopositioners, special cryostats, or free-space optical access.
This technology also enables the simultaneous integration of eDelight with superconducting nanowire detectors in cryogenic systems.
