钟山论坛 奥地利科学院院长Zeilinger教授学术报告 From Quantum Puzzles to Quantum Information Technology

Abstract: Quantum physics provides interesting conceptual puzzles. The basic fundamental ideas in the puzzles include quantum superposition (like in Schroedinger's cat), quantum entanglement (called by Einstein spooky action at a distance) and quantum randomness (viz. Einstein's comment that God does not play dice). To date, the same fundamental concepts just mentioned led to novel information science concepts and thus became the basis for the emerging quantum information technology which includes such concepts as quantum teleportation, and quantum computation. The future quantum internet will combine these ideas. It will consist of quantum computers connected by quantum links carrying photons. From a fundamental point of view, fundamental experiments have sharpened our basic questions about the nature of quantum systems.
