Quantum Sensing Paradigm Could Create Opportunity in Imaging Capabilities

Quantum entanglement could take GPS to the next level

In brief…

+  RF waves are usually received by a network of sensors, each of which processes information individually — more like a group of independent employees working with their supervisors. Quntao Zhuang, UA assistant professor of electrical and computer engineering, previously demonstrated a theoretical framework to boost performance by teaming up entangled sensors.

“Imagine, for example, a network for biological sensing: You can entangle these biosensors so that they work together to identify the species of a biological molecule, or to detect neural activities more precisely than a classical sensor array,” Zhang said. “Really, this technique could be applied to any application that requires an array or network of sensors.”

+  “Typically, in a complex system — for example, a wireless communications network or even our cellphones — there’s not just a single sensor, but a set of sensors that work together to undertake a task,” Zhang said. “We’ve developed a technology to entangle these sensors, rather than having them operate individually. They can use their entanglement to ‘talk’ to each other during the sensing period, which can significantly improve sensing performance.”

+  This new experiment demonstrated for the first time that a network of three sensors can be entangled with one another, meaning they all receive the information from probes and correlate it with one another simultaneously. It’s more like if a group of employees could share information instantly with their bosses, and the bosses could instantly share that information with each other, making their workflow ultra-efficient.
