Here we develop the first optical relay to reshape the wavefront of photons for their low diffraction loss in free-space transmission. Using two drones, where one distributes the entangled photons and ...

During the experiments, Jinan-1 established optical links with multiple optical ground stations in Jinan, Hefei, Nanshan, Wuhan, Beijing, Shanghai, in China, and Stellenbosch in South Africa.

Device Encryption Optical Transmitter' Based on Eco-Friendly Quantum Dots- New Li-Fi Platform Technology Achieves High ...

Optical Society of America Summary: When the military needs to send the key to encrypted data across the world, it can't necessarily rely on today's communication lines, where the message could be ...

S hanghai Jiao Tong University has just solved one of the oldest telecom headaches. The faster you fling information down a light beam, the harder it is to keep it secret. In lab and field tests ...

A groundbreaking integrated encryption and communication (IEAC) framework, enabled by end-to-end deep learning, has achieved a record-breaking single-channel secure transmission rate of 1 Terabit ...

This is the second in a series of explainers on quantum technology. The other two are on quantum computing and post-quantum cryptography. Barely a week goes by without reports of some new mega ...

Quantum communication, or quantum key distribution, provides security when sending data by using the laws of physics. It allows two parties to share encrypted data that is transferred through ...

“Theoretically speaking, quantum communication is completely encrypted,” explains Prof. Oz. “It is impossible to launch a cyber attack and copy the information, because in quantum mechanics ...

Quantum communication uses the properties of quantum physics to relay encrypted messages from point A to point B. This is a technology that aliens may have already conquered.
