Google has solved a key problem in quantum computers

A key problem hindering development of quantum computers is now Google and researchers at the University of California, have found a solution. Of course, this just came up with the solution to one problem from actually solve all the problems a quantum computer, we faced a lot of difficulties, but experts in the field say, towards the development of a fully functional quantum computer represents an important step forward. Quantum computers can quickly calculate the traditional computer take millions of years to complete the task.

Google and the University of California researchers show that they can program the quantum dots, programmed device using quantum physics to information, also can detect certain types of errors, these errors and prevent the interference calculation. The new progress comes mainly from the researchers led by John Martinis, John Martinis is a professor at the University of California, at the same time he also joined Google last year and set up a quantum computing research laboratory.

Google has been exploring since 2009 quantum computers, Google and D-Wave Systems to work together at the outset of this project, which is a startup company and sold the first commercial quantum computer. Microsoft also has a fairly large scale quantum computer research projects.

In order to make a quantum computer can run efficiently, you need to make a quantum computer connection a lot of quantum dots, which can aggregate information to. But the device is very easy to make mistakes, because they are only 0 and 1 bits, and can be detected only at extreme low temperatures and small scale problems. This study makes quantum dots can have a "superposition" can be a valid expression 1 and 0, a quantum computer can have a faster way to do complex calculations; making quantum computers are not vulnerable to heat and other coded information and perform calculations of interference.

Many quantum computation research focused on trying to make quantum dots system to detect and fix bugs. Martinis's team have proved that they are a more effective programme, referred to as code. Researcher to program the chip-9 quantum dots, so that they can monitor each other as "bit flips" error, which is the environmental noise 1 flip to 0, or 0 issues over to 1. GUCCI iPhone 6 Case

Although only a small number of quantum dots program, but the Martinis and the team is optimistic that, full set of error correction techniques can be achieved shortly. Once, brought about by the scientific and commercial value of the quantum computer will be immeasurable.

Maybe HTC in the Android camp has typical of industrial design, coupled with the previous generation M8 public expectations have been raised too high, so at the press conference following the end of routine upgrades of the M9 and not so strong repercussions. Discussion on the M9, consumer channel is highly concentrated on the legendary "three-jaw" and "around the Israeli-Palestinian" "Wu Chin" ...
