Now, it’s time for Coherence, the quantum executive summary where I take a moment to highlight some of the business impacts we discussed today in case things got too nerdy at times. Let’s recap.
Oxford Quantum Circuits, or OQC, spun off from the University of Oxford in 2017 and has been working on bringing Coaxmon technology to the world. Coaxmon is a 3D integrated solution for transmon superconducting quantum processing units, or QPUs. The hope is to achieve low-cost, scalable, stable qubits. The company builds all its own control hardware too, and the software stack.
Coaxmon processors are similar to other transmon processors in that the same support electronics for the qubit like a resonator, control lines, etc. are present. However, in traditional transmon chips, those elements have to be routed on a flat 2D plane to each of the qubits. In Coaxmon, these control elements are instead incorporated above and below the actual qubit itself. If you imagine each qubit as a cylindrical unit, you can see how it’ll be easier to fit more of them closer together by taking advantage of that three-dimensional space. Complicated arrays and patterns can be built without worrying about how to route control circuitry to the qubit itself.
OQC considers itself a quantum computing–as–a–service company, not just a qubit manufacturer. They’re concern with all layers of the stack. Their first eight-qubit machine is called Lucy. Lucy can be accessed by Amazon Braket, but OQC also has a private cloud that allows direct access. You can use an API key and select Lucy as a target. In the U.K., there are hours of availability for Lucy to minimize wait times for local companies. Customers in other regions can access as well, and the hope is to optimize queues based on time zones. Having the machine in the U.K. is important for companies concerned with the GDPR and not letting information cross borders. Even though quantum computers don’t technically access sensitive information, the concerns are still there.
Amazon has been working on hybrid jobs. Here, AWS classical hardware is used for parts of the task where it will excel while quantum computers are handed parts of the task where they will excel. Lucy is ready to work with this solution today, as OQC’s stack has already met many of Amazon’s requirements for hybrid jobs. This hybrid approach is where quantum and cloud will come together synergistically in true production use cases in the future.
