Unlike classical computer systems, quantum computers usually work at low temperatures However, quantum brilliance, a joint venture between Australia and Germany, has launched a diamond based quantum accelerator, which can be put into use at room temperature
Access:
The world's first room temperature local quantum computer was installed at the Pawsey Supercomputing Center in Australia. Although we don't have much information about the computing power of the system, we know that its performance is comparable to that of Pawsey's HPE Cray ex supercomputer HPE Setonix.
In a short YouTube video shared by Pawsey, it was emphasized that the benefits of using quantum accelerators are manifold. They are trying to integrate them into the central hardware and software stack for better use.
At present, the internal information about quantum brilliance diamond accelerator is not very detailed. The company is using the nitrogen vacancy (NV) center in diamonds, which is presumed to have the longest coherent time in any room temperature quantum state.
