Quantum information is notoriously fragile. Internet traffic is anything but. Yet Northwestern University scientists have ...

In 2024, scientists demonstrated quantum teleportation through a laboratory optical cable carrying high-speed internet ...

Any time you use a device to communicate information—an email, a text message, any data transfer—the information in that transmission crosses the open internet, where it could be intercepted. Such ...

Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines. Instead of beaming people or objects across space, physicists are learning ...

Quantum signals are extremely fragile and can be overwhelmed by the intense optical noise generated by conventional internet traffic, requiring costly dedicated infrastructure for quantum networks.

The emergence of quantum entanglement is one of the fastest processes in nature. Scientists show that using special tricks, this can be investigated on an attosecond scale. Scientists have managed to ...

ISTA physicists have confirmed a theory proposed 20 years ago that could advance quantum technology.

Quantum entanglement, an inextricable link between particles, is an important resource for quantum computing and communication – and in some cases, it may also be a resource that can be shared nearly ...

Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum ...

Nearly a century ago, the physicist Erwin Schrödinger called attention to a quirk of the quantum world that has fascinated and vexed researchers ever since. When quantum particles such as atoms ...
