Resetting qubits is a major bottleneck in quantum computing. A new refrigerator that runs on heat—not electricity—is on the horizon. The result? A superconducting qubit that cools itself.

International study shows a quantum process may appear without past influence in one description but retain it in another, opening paths for better quantum devices.

IBM aims to build a fault-tolerant quantum computer by 2029, capable of solving complex problems faster and more efficiently than traditional computers.
