Safeguarding data in future quantum computing: Physicists detect and control quantum states in diamond with light

Academics / General Science : ScienceDaily: Science Society

Physicists have succeeded in combining laser light with trapped electrons to detect and control the electrons' fragile quantum state without erasing it. This is an important step toward using quantum physics to expand computing powe...

Improved interface for a quantum internet

Academics / General Science : ScienceDaily: Science Society

A quantum network requires efficient interfaces over which information can be transferred from matter to light and back. Physicists now show how this information transfer can be optimized by taking advantage of a collective quantum ...

Quantum criticality observed in new class of materials

Academics / General Science : Science Codex

Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study. But a new discovery of "quantum critical points" could allow physicists to de...

Entering the quantum Internet at the speed of light

Academics / General Science : TG Daily - General Sciences

A team of Innsbruck University physicists have managed to directly transfer the quantum information stored in an atom onto a particle of light - theoretically allowing data to be sent over optical fiber to a distant atom. read more

Doing more with less: Steering a quantum path to improved internet security

Academics / General Science : ScienceDaily: Science Society

New research may lead to greatly improved security of information transfer over the internet. Physicists have demonstrated the potential for 'quantum steering' to be used to enhance data security over long distances, discourage hack...
