Confidential patient data, bank details and highly sensitive government and military information must be increasingly ...

In a groundbreaking achievement for quantum technologies, researchers have created a functional quantum register using the atoms inside a semiconductor quantum dot.

Yet many emerging quantum applications—such as quantum relays, repeaters, and networked quantum computers—rely on teleporting quantum states rather than transmitting them physically.

This capability is vital for building quantum repeaters that can extend the range of quantum communication networks. Additionally, the exploration of rare-earth ions, particularly erbium (Er3 ...

“It is another application needed to achieve operations such as distributed quantum computing, sensing, and quantum repeaters,” concluded Thomas. The research findings were published in Optica.

and lays out the foundations for the construction of multiplexed quantum repeaters in an integrated configuration and high-capacity transportable quantum memories. These results have been ...

Repeaters were spaced every 50 km or so along ... EDFAs leverage the principles of quantum physics and yet are surprisingly simple. EDFAs rely on the fluorescent properties of oxides of the ...

In an advance for quantum technologies, researchers at the Cavendish Laboratory, University of Cambridge, have created a ...
