11 May 2022 – QuiX Quantum, the market leader in photonic quantum computing hardware, has realized the largest quantum photonic processor compatible with quantum dots for the European project PHOQUSING. The project aims to realize a quantum sampling machine that will push the potential of photonic quantum computing forward in showing a European quantum advantage. The processor realized by QuiX Quantum is the core component of the quantum sampling machine.
Thanks to its unique and mature technology, QuiX Quantum delivers a record-size 20-mode quantum photonic processor compatible with quantum dots sources for Europe. The processor is one of the key components of a near-term quantum computing device, i.e., a quantum sampling machine, able to show a quantum advantage. This achievement strengthens the position of QuiX Quantum as European leader in the quantum hardware market. QuiX Quantum processors are now the de-facto standard for photonic quantum information processing in Europe, being in use by the French, German, British, and Hungarian quantum ecosystems.
Quantum sampling machines based on light are believed to be very promising for showing a quantum advantage. The problem of drawing samples from a probability distribution, mathematically too complex for a classical computer, can be solved easily by letting light propagating through such quantum sampling machines. At the very core of quantum sampling machines there are large-scale linear optical interferometers, i.e., photonic processors.
The PHOQUSING project brings together the leading European academic (Sapienza, IFN-CNR, LIN, CNRS, Sorbonne Université) and industrial players (QuiX Quantum, Veriqloud) of quantum information processing and integrated photonics.
Prof. Fabio Sciarrino of the Physics Department of Sapienza Universitá di Roma, coordinator of the project,says: ”The established high-performance photonic technology provided by QuiX Quantum is crucial for the success of the project as it addresses the need of science-to-technology transition needed for developing useful quantum computation”. This work has received funding from the European Union’s Horizon 2020 research and innovation programme under the PHOQUSING project GA no. 899544.
QuiX Quantum is a quantum technology firm located in Enschede, the Netherlands, and is a spinout of the University of Twente, with the main investors being Forward One and Oost NL. The delivered 20-mode processor, working at 925 nm, consolidates the recently released product line of quantum photonic processors compatible with quantum light sources in the near-infrared wavelength range.
