INTERESTING ENGINEERING - Quantum computing’s ability to solve problems that would take classical computers millennia has captured global interest. But the path to functional, scalable quantum machines has been riddled with fundamental challenges. At the heart of the problem lies the qubit, the quantum version of a digital bit. Qubits can exist in multiple states...
LIVE SCIENCE - A new superconductor material could greatly improve the reliability of quantum computers, scientists say. The electrical resistance of materials typically decreases as they are cooled. But some materials, called superconductors, maintain a gradually declining electrical resistance until they are cooled to their critical cut-off temperature, at which point their resistance becomes zero...
