Researchers take quantum encryption out of the lab

In a new study, researchers demonstrate an automated, easy-to-operate quantum key distribution (QKD) system using the fiber network in the city of Padua, Italy. The field test represents an important step toward implementing ...

When memory qubits and photons get entangled

Encrypting data in a way that ensures secure communication is an ever-growing challenge because crucial components of today's encryption systems cannot withstand future quantum computers. Researchers around the world are ...

The world's first integrated quantum communication network

Chinese scientists have established the world's first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a ...

How astronomers can leverage fiber nets and listen to deep space

For the first time, researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometers over a standard fiber optic telecommunications network and used to synchronize two radio ...

Researchers break data transfer efficiency record

Researchers at the Department of Energy's Oak Ridge National Laboratory have set a new record in the transfer of information via superdense coding, a process by which the properties of particles like photons, protons and ...
