The Sussex team have shown how calculations in such a quantum computer can be done most efficiently, by using their new 'routing algorithm'. Their paper "Efficient Qubit Routing for a Globally Connected Trapped Ion Quantum Computer" is published in the journal Advanced Quantum Technologies.

The team working on this project was led by Professor Winfried Hensinger and included Mark Webber, Dr Steven Herbert and Dr Sebastian Weidt. The scientists have created a new algorithm which regulates traffic within the quantum computer just like managing traffic in a busy city. In the trapped ion design the qubits can be physically transported over long distances, so they can easily interact with other qubits. Their new algorithm means that data can flow through the quantum computer without any 'traffic jams'. This in turn gives rise to a more powerful quantum computer.
