Quantum Computers

Lack of data Today's technology allows you to compress logic gates and wires of a few million microns across the surface of silicon chips. The door itself will be made up of several atoms, but this is a matter of time. On this scale, the substance follows the law of quantum mechanics. If computers become smaller and more powerful in the future, quantum technologies must replace or enhance what we have today. Quantum computers are not limited by the dual nature of the classical physical world.

Quantum computation is studying a theoretical computation system (quantum computer) that manipulates data directly using quantum mechanical phenomena such as overlap and entanglement. Quantum computers are different from transistor based binary digital computers. Conventional digital computing requires that each numerical value always encode data in binary numbers (bits) in one of two determined states (0 or 1). Quantum Turing machine is a theoretical model of such a computer, also known as a general quantum computer. The field of quantum computing was launched by Paul Benioff and Yuri Manin in 1980, by Richard Feynman in 1982, and by David Deutsch in 1985. Spin quantum bits of quantum computers are also used for quantum space time. 1968

Quantum computation uses quantum mechanics components to analyze data. Quantum computers use quantum bits (qubit) instead of binary numbers (bits) to store information. Thus, a classical computer data point has zero or one state, but the qubit has "superposition" of states, ie multiple values ​​at the same time. As a result, the quantum computer stores a large amount of data and can use less energy than conventional computers. Several quantum processors are 100 million times faster than existing quantum processors

72 may not be that large number, but for quantum computing it is huge. This week, Google announced Bristlecone. This is a new quantum computing chip with 72 qubits, a quantum bit which is the basic unit of quantum bit computation. As our quantum bit counter and timeline show, the previous record holder was a 50-bit processor announced by IBM last year. John Martinis, who is in charge of Google's efforts, said the team still needs to continue testing, but this year it is probably "probable" that even though just a few months new chips can achieve "quantitative priority" ing. This is the key of a quantum computer that can perform calculations beyond the range of the fastest supercomputer today.
