quantum computing

Scientists have identified a method to create multiple copies of quantum information by encrypting them with a one-time decryption key, sidestepping the no-cloning theorem. This approach, developed by Achim Kempf and colleagues at the University of Waterloo, was tested on an IBM quantum processor. The technique could enhance redundancy in quantum computing and storage systems.

Researchers have used quantum superposition to help qubits violate a fundamental quantum limit, allowing them to maintain information five times longer. This breakthrough involves a three-qubit system that demonstrates extreme correlations over time. The finding could enhance quantum computing and metrology applications.
