Xanadu, a Toronto based quantum computing startup, has released their Borealis processor and has made it available on the Xanadu Cloud. They will also make it available soon on the Amazon Braket cloud service. In addition, Xanadu has demonstrated Quantum Supremacy with this device by running a Random Number Sampling experiment on it use Gaussian Boson Sampling. This demonstration is similar to those performed by Google in October 2019 with their superconducting based device and also by the University of Science and Technology China (USTC) with their Gaussian Boson Sampler in December of 2020.
Note: The Quantum Computing Report uses the term Quantum Supremacy for a demonstration of running an algorithm beyond what a classical computer is capable of doing. However, a Quantum Supremacy demonstration does not require running an algorithm which is commercially useful. Sampling the distribution of random numbers is noteworthy but has negligible commercial use. We reserve the term Quantum Advantage for running a commercial useful algorithm beyond the capability of a classical machine.
The architecture of the Borealis machine is interesting because it uses time-multiplexing to achieve the 216 qubits rather than creating specific hardware for each individual qubit. Borealis can be programmed using Xanadu’s Strawberry Fields software designed for constructing, simulating, and executing programs on photonic quantum computers.
