Advanced research in quantum sensors

We pursue quantum technology solutions because they allow us to create sensors which can sense electro-magnetic signals to a degree that classical technologies would never achieve.

Dr Giuseppe Tettamanzi explains "Using the principles of quantum mechanics, we developed a sensor which can detect electromagnetic (EM) signals across the widest range of frequencies ever achieved in a single device."

"This is possible because we can design and operate our structures in the most optimal way so they are limited only by quantum noise, with all other sources of noise suppressed. The technology is of great interest to the defence sector, but it is also important for medical purposes because we can detect tiny electromagnetic signals in the heart, brain or spine using the same technology, allowing for more precise diagnoses and therefore more targeted treatments."

Being able to pick up signals this precisely is also valuable for the space industry. As we venture further from Earth, these devices are prime candidates for enabling reception of EM signals to and from the Moon, Mars and further. "Our project is now working to determine the sensor’s limits and identify ways to scale the technology up or down for use in other ways," says Giuseppe.

"A limitation is that the sensor needs to be operated in a low temperature environment. In the past, low temperature operation created problems as the cryogenic setups needed were large, heavy, noisy, invasive, and difficult to operate. These cryo-setups are now scaled to tens of centimetres sizes and need very little power to operate, making DSI’s approach extremely appealing for a wide range of critical applications."
