    A quantum computer Google has completed in 200 seconds, a task that the computer conventional the world’s fastest it would take about 10,000 years to make, according to an article published Wednesday in the scientific journal Nature.This demonstration of the supremacy quantum is a milestone for quantum computing, a computer system that aims to perform tasks exponentially more quickly than the computers classic and conventional with a low rate of error.Unlike computers classical computers quantum use a system of cúbits (quantum bits) that store information in the two figures of the binary code, 1 and 0, while the machines classic used bit and must choose between storing data in one of the two digits, 1 or 0. With this new protocol, known as superposition, the machines quantum can quickly solve problems of great complexity and process vast amounts of data. The work, led by the responsible computing quantum Google at the University of California (EE.USA), John Martinis, describes the technical steps made to achieve the supremacy quantum.According to the article, the researchers manufactured a processor composed of 54 cúbits, which takes advantage of the superposition and entanglement quantum to explore a space computational exponentially greater that provided by the classical bits. A cúbit not worked correctly, the device worked with 53 cúbits.The team developed processes of error correction to maintain a high-fidelity operational (up to 99,99%).To test the system, they designed a task of sampling random numbers produced by circuit quantum. The processor picked up a million samples in about 200 seconds, which would have led to a súperordenador of last generation about 10,000 years ago. “This demonstration of the supremacy of quantum on the main classical algorithms present in the main supercomputers of the world is really a remarkable achievement,” says William Oliver, a researcher at the Department of Computer Engineering and Physics at the Massachusetts Institute of Technology (MIT).Oliver writes in the same number of Nature a paper published The quantum computing takes off in which he also points out that there is more work before that quantum computers will become a practical reality.
