Quix Quantum Introduces a New 20 Qumode Photonic Quantum Processor

Quix Quantum, a quantum technology firm located in Enschede, the Netherlands, and a spinout of the University of Twente, has updated its processor lineup. Its new 20 qumode processor is both higher in capacity and also better in quality than their previous generation 12 qumode processor. Qumodes are often used in quantum photonic processors instead of qubits. Qumodes are different from qubits because they are continuously variable and, in theory, a qumode can be at least as powerful, or perhaps, even more powerful than a qubit. (For an explanation of Qumodes, you can see a two-part blog explaining it on the Quix Quantum website. Part 1 is here and Part 2 is here.)

The new processor, named the Dolphin20_1550, has substantially lower loss characteristics than the predecessor. Here is a table provided by Quix that compares the two:
