Quantum teleportation is a fascinating process that involves transferring a particle's quantum state to another distant location, without moving or detecting the particle itself. This process could be central to the realization of a so-called "quantum internet," a version of the internet that enables the safe and instant transmission of quantum information between devices within the same network. /news/2025-07-quantum-internet-closer-teleport-based.html General Â鶹ÒùÔºics Quantum Â鶹ÒùÔºics Mon, 21 Jul 2025 10:30:12 EDT news672310600 Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure communication at scale, and to connect quantum computers globally.

People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also key in security; if a password or code is an unguessable string of numbers, it's harder to crack. Many of our cryptographic systems today use random number generators to produce secure keys. /news/2025-06-quantum-mechanics-random-demand.html Quantum Â鶹ÒùÔºics Wed, 11 Jun 2025 11:00:11 EDT news668766840 Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if nonlinear optical processes were used.
