Difficulty in maintaining the quantum state of subatomic particles is a major challenge in developing quantum computers. Princeton researchers have managed to maintain quantum data through use of diamonds infused with two carbon atoms per every silicon atom. These ‘flawed’ diamonds ‘could serve as quantum repeaters for networks based on qubits’ just as current networking systems have repeaters to keep signals strong between sender and receiver.
Computer science theorists have been troubled with answering just what problem could a quantum computer solve that a classical computer would ever possibly accomplish. Collaboration between Princeton University and Stanford University theorists believe they have an answer – finally. This piece explores the question: “[We] want to know, where does quantum computing fit into the world of classical complexity theory?”
What Is The Quantum Computing Equivalent of a Wire? Light. Researchers across several institutes have managed to harness electromagnetic wave properties of light, encoding the
