Securing wireless communication in next-generation devices
A new, scalable technique could enable powerful radars and sensors based on quantum technology that works at room temperature.
MIT researchers have developed a new method to generate pairs of highly correlated radio frequency waves for secure communications and advanced signal processing at room temperature, overcoming a major hurdle for practical quantum technologies. The team created a compact electronic device that utilizes a magnetic film and a metal cavity to split incoming microwave signals into two linked output signals without the need for expensive cooling equipment.
These correlated signals can be used for noise-resistant communication, high-precision radar, and sensing applications. The researchers demonstrated the potential of their platform by encoding information in a signal and successfully decoding it using its partner. By leveraging the quantum properties of magnets, the device can encode data in a signal, which can only be decoded using the matching signal, ensuring secure communication.
The researchers hope their work will pave the way for the development of room-temperature quantum simulators, which have the potential to enable numerous future discoveries.
