indie’s LXM-U Laser Enhances Quantum Computing and Secure Communications with Ultra-Low Noise Technology

indie  has introduced its LXM-U laser, designed to support quantum applications through enhanced frequency stability and integration capabilities. The laser is part of indie’s Photonics Business Unit, formed earlier this year by combining its Canadian photonics team, previously TeraXion, with a portfolio of laser and optical components, and its recently acquired EXALOS team in Switzerland, which specializes in super luminescent diodes (SLEDs) with photonic integration capabilities. The Photonics Business Unit focuses on automotive Advanced Driver Assistance Systems (ADAS), including LiDAR, and emerging industrial markets.

The LXM-U, a narrow-linewidth semiconductor laser, is tailored for quantum technologies, specifically quantum key distribution (QKD) and quantum computing. It features ultra-low-frequency noise, reported to be 10 times lower than competing technologies, and narrow-linewidth characteristics, providing the precision and stability needed for demanding quantum applications. The laser’s long-term stability supports locked operation for extended periods, facilitating reliable cryptographic key transmission.

Mathieu Drolet, Executive Vice-President of indie’s Photonics Business Unit, stated that the company is collaborating with leaders in quantum computing, providing solutions that leverage the LXM-U laser’s capabilities...
