From Cats to Cameras: A Quantum Story

Matthew Dale asks whether quantum technologies are ready to be seen on the global stage at one of the world’s largest photonics exhibitions

QuiX Quantum announces quantum light sources

QuiX Quantum, the market leader in photonic quantum computing hardware, has announced a new product line of quantum photonic processors, which are compatible with quantum light sources in the near-infrared wavelength range (900-970 nm), including InGaAs quantum dots.

This product line complements QuiX Quantum’s existing offerings of quantum photonic processors at telecom wavelength, and near-term quantum computers. The processor offers the record specifications that have become a hallmark of QuiX Quantum’s devices.
