Researchers demonstrate how qubit leakage, traditionally a source of decoherence in noisy environments, can be harnessed as a mechanism for generating quantum entanglement without physical transport of particles. This approach offers a potential pathway toward more robust quantum networks by converting environmental noise into useful computational resources rather than treating it solely as an error to be corrected.

Quantum entanglement without transport: Leaky qubits offer route around noisy channels

Phys.org19 iulie 20261 min de cititArticolul și perspectiva sunt în engleză.

The inevitable leakage of energy and information from a quantum system into its surrounding environment is the enemy of quantum technology. Now, researchers have demonstrated that it can be exploited to generate entanglement—the "resource" that quantum technologies use to perform tasks inaccessible to standard classical technologies.
