How Quantum Sensors Conquer Their Own Noise

Scientists have proven that quantum sensors can reach absolute accuracy, even if all their components are noisy. They've developed a fault-tolerant protocol that achieves the fundamental Heisenberg limit when measuring magnetic fields. This brings us closer to building reliable quantum sensors for s

Quantum Abacus: Cracking Codes with 10,000 Atoms

Previous estimates demanded millions of qubits for quantum decryption. New research shows that just 10,000 movable atoms, like abacus beads, will do. With laser tweezers and error-correcting codes, RSA-2048 could be broken in days.
