Photonic quantum processor operates in near-infrared
QuiX Quantum BV (Enschede, The Netherlands) has developed a 12-qumode quantum photonic processor, compatible with near-infrared wavelengths of 900 to 970nm; including InGaAs quantum dots.
The company, a spin-off from the University of Twente, was founded in 2019 to develop an optical processor for quantum computing capable of room temperature operation. It uses silicon-nitride waveguides on silicon or glass substrates.
The near-infrared product line complements QuiX Quantum’s existing offerings of quantum photonic processors at telecom wavelength 1550nm, and near-term quantum computers.
The addition of 900nm to 970nm wavelength operation enables integrated quantum photonic information processing using single photon sources such as InGaAs quantum dots. The details of the processor are disclosed in a scientific publication available on the arXiv repository, available at https://arxiv.org/abs/2204.05768.
