Researchers from North Carolina State University and the Massachusetts Institute of Technology have designed a protocol for harnessing the power of quantum sensors. The protocol could give sensor designers the ability to fine-tune quantum systems to sense signals of interest, creating sensors that are vastly more sensitive than traditional sensors.
“Quantum sensing shows promise for more powerful sensing capability that can approach the fundamental limit set by the law of quantum mechanics, but the challenge lies in being able to direct these sensors to find the signals we want,” says Yuan Liu, assistant professor of electrical and computer engineering and computer science at NC State and corresponding author of the research. Liu was formerly a postdoctoral researcher at MIT.
“Our idea was inspired by classical signal processing filter design principles that are routinely used by electrical engineers,” Liu says. “We generalized these filter designs to quantum sensing systems, which allows us to ‘fine-tune’ what is essentially an infinite dimensional quantum system by coupling it to a simple two-level quantum system.”
