The Institute for Quantum Computing (IQC) of the University of Waterloo has developed a new quantum sensor that can improve the treatment of cancer. The device is based on the advanced long-range 3D imaging.
This research was done with the collaboration of researchers from the Eindhoven University of Technology and published in Nature Nanotechnology on March 4, 2019.
Researchers have designed this sensor which can absorb and identify a single particle of light which is known as photon. According to the reports, this sensor device uses semiconductor nanowires and can work on high timing resolution.
Also, it can monitor the speed and the efficiency over an unparalleled wavelength range from ultraviolet to near-infrared waves all at room temperature. This device arranges tapered nanowires that converts incoming photons into electric current. It can also amplify and detect the rays.
This robust single photon detector can also be useful for remote sensing and improving quantum communication. This sensor can also provide oxygen detection that monitors every dose in cancer treatment.
Michael Reimer, the principal investigator, and an IQC faculty member said, “This device uses Indium Phosphide (InP) nanowires. Changing the material to Indium Gallium Arsenide (InGaAs), for example, can extend the bandwidth even further towards telecommunications wavelengths while maintaining performance.”
In addition, he said, “A broad range of industries and research fields will benefit from a quantum sensor with these capabilities. His focus is primarily on broadened the spectrum of absorption with different the use of different materials.”
Researchers have claimed that this device is fast and efficient in absorbing and detecting every single light particle within nanoseconds. However, it has the potential for further enhancements with more research.
