Quantum computing is the most ambitious and far-reaching quantum technology, with photonics offering the most promising way forward with the ability to achieve the minimum 1 million stable, error-corrected qubits that will likely be required to produce the first useful quantum computer.

Before the advent of integrated quantum photonics, state-of-the-art photonics involved bulky, unwieldy apparatus. Bristol’s Quantum Engineering Technology Labs was the first to combine quantum photonics and microfabrication to deliver an integrated photonic quantum logic gate on a chip. This early breakthrough generated a combined body of over 100 publications and paved the way for a vibrant ecosystem of quantum technology start-ups, supported by a world-leading training centre, the Quantum Technologies Enterprise Centre (QTEC).

The world’s most highly funded quantum computing start-up used Bristol research to raise USD215M and create over 100 jobs. PsiQuantum developed silicon photonic quantum circuits which paved the way for scalable, room-temperature quantum computers.

Currently, Bristol’s research has led to the establishment of 31 businesses, a combined investment of £44.8M and the creation of 126 new highly skilled jobs. Its spin outs are delivering secure telecommunications, reducing reliance on broad-spectrum antibiotics in healthcare, combating climate change and much more.

A further £91m has been secured to grow this vibrant technology ecosystem with the introduction of a new commercial incubator and accelerator, Quantum Technologies Innovation Centre (QTIC+).
