Quantum computers can be accessed over the Internet in a variety of ways. However, the vast majority of these machines are older models with limited capabilities. It’s good for education, but you can’t use it for anything practical.
Xanadu is Canada’s leading photonic quantum hardware provider and one of the world’s most innovative companies. Xanadu’s mission, since its inception in 2016, has been to build quantum computers that are both useful and accessible to everyone.
They’ve announced a computer that they claim is capable of achieving quantum advantage and that anyone can use, subject to certain restrictions. There are over 216 squeezed-state qubits in Borealis, the computer in question, which uses photonic states.
However, the company is charging for time on the computer, but the free tier includes 5 million free shots on Borealis and 10 million free shots on a previous quantum computer model. A million shots on Borealis cost about $100 if you pay as you go.
Despite the fact that a few million images may sound like a lot, we noticed that the QuickStart demo consumes 10,000 shots, and that’s likely something simple. That works out to about 500 runs on Borealis, which isn’t bad for a free quantum computer. However, a simulator will be required for debugging.
Borealis Quantum Computing Key Features
- Quantum computing-advantage level performance can be accessed via the cloud.
- Trains of up to 288 squeezed-state qubits can be emitted by a quantum light source with adjustable brightness.
- Programmable interferometer for Gaussian Boson Sampling, with loop-based interferometer for large entangled state syntheses
- Programmable — you can change the gate parameters to suit your needs as you go along.
- The use of photon-number-resolving detectors for high-speed processing and reading.
