Mass manufacturing of quantum sensors on CMOS
A team of UK researchers has developed a way to use microring optical resonators as quantum sensors. These can be easily made in volume using today’s chip manufacturing process technology, allowing integration of the sensors with processing.
The majority of quantum sensing schemes rely on special entangled or squeezed states of light or matter that are hard to generate and detect. This is a major obstacle to harnessing the full power of quantum sensors and deploying them in real-world scenarios.
The team of physicists at the Universities of Bristol, Bath and Warwick used the microring resonators to sense absorption or refractive index changes can be used to identify and characterise a wide range of materials and biochemical samples, with applications from monitoring greenhouse gases to cancer detection.
“We are one step closer to all integrated photonic sensors operating at the limits of detection imposed by quantum mechanics,” said Alex Belsley, Quantum Engineering Technology Labs (QET Labs) PhD student and lead author of a paper published in Physical Review Letters.
