Researchers have discovered a way to entangle photons to help lasers penetrate fog and aid in surveillance.

Led by Jung-Tsung Shen, the team at the McKelvey School of Engineering at Washington University conducted the Defense Advanced Research Projects Agency (DARPA) backed research.

The research could have interesting military applications, once refined.

Adverse conditions, such as fog, extreme temperatures, or long distances, can hamper military surveillance and communication. However, as Shen discovered, using the power of quantum entanglement offers an innovative way to overcome this.

His quantum photonic-dimer laser solution has attracted a $1 million DARPA grant. This device carefully controls pairs of light particles or photonic dimers, which are used to generate a powerful and concentrated beam of light or laser.

Quantum photonic-dimer lasers use quantum effects to bind two photons together, increasing their energy, efficiency, and range.
