BEIJING, May 23 (Xinhua) -- On a table of 3 square meters are dozens of lenses and odd devices, with wires suspended above and a machine chirping ceaselessly. It is a prototype #quantumcomputer developed by about 20 Chinese scientists at the Shanghai-based Institute for Quantum Information and Quantum Technology Innovation of the Chinese Academy of Sciences (CAS). The "baby" quantum computer, unveiled in early May, is the first quantum computing machine based on single photons that could go beyond the early classical -- or conventional -- computer. The principle of quantum computing is based on one of the strangest phenomena in quantum physics: quantum entanglement. The ancients would see modern electronic technology as akin to witchcraft; most people today would have a similar view of future quantum computing technology. Scientists say quantum computing exploits the fundamental quantum superposition principle to enable ultra-fast parallel calculation and simulation capabilities. In normal silicon computer chips, data is rendered in one of two states: 0 or 1. In quantum computers, data can exist in both states simultaneously, holding exponentially more information. The computing power of a quantum computer grows exponentially with the number of quantum bits that can be manipulated. This could effectively solve large-scale computation problems that are beyond the ability of current classical computers, scientists say.
