Our recent paper in Nature Communications explains how we might be able to break up a quantum computer into little, easy to make pieces and then network them together.

A quantum error-correcting code is a central piece of fault-tolerant quantum computation that is required to realise large-scale quantum algorithms. Unfortunately, the state-of-the-art codes with the best parameters that require the least overheads do not Read more…
The most promising class of algorithms for near-term quantum computers are variational quantum algorithms (VQAs), where a parametrised circuit of quantum gates calculates some cost function, which is then optimised to produce the solution to Read more…
A promising approach to build a scalable quantum computer is to manufacture a large array of qubits on a chip. This is common to several hardware architectures including superconducting qubits and spin-qubits in silicon. The Read more…
