Google Breakthrough in quantum computing: The experimental computer solved a task in 200 seconds for which the currently fastest supercomputer would take 10,000 years. However, the technology is not yet practical.
Google claims that it has taken an important step in the development of quantum computers. With the help of its processor Sycamore, it is possible to do a calculation in 200 seconds, for which the currently fastest supercomputer would take 10,000 years, the researchers write in a report published on Wednesday in the science journal “Nature” . This is the first time that the demonstration of “quantum superiority” has been achieved.
Quantum computers many times faster than classic computers
Scientists have been looking for new ways in computer technology for decades. They hope from quantum computers that certain computing tasks can be performed many times faster than with classic computers . While in a binary computer the smallest units, called bits, either assume the state 0 or 1, the “qubits” of the quantum computer follow the laws of quantum mechanics – they can represent several states at the same time.
If you think you understand quantum mechanics, you don’t understand quantum mechanics Google chief Sundar Pichai
This paradox is still considered a challenge even in theoretical physics. Google boss Sundar Pichai also quotes the American physicist and Nobel laureate Richard Feynman in his blog entry: “If you think you understand quantum mechanics, you don’t understand quantum mechanics.”
Pichai is modest given the milestone that may have been reached. Meanwhile, IBM downplayed the success now achieved and says that there was a mistake in Google’s bill. The same task can be solved with a classic system in just 2.5 days, according to a blog post by the quantum computer competitor.
On NASA’s website (Google Breakthrough in quantum computing)
About four weeks ago, the specialist article by Google researchers had already appeared. It had been available on the NASA website for a short time, but disappeared shortly afterwards. This had already caused a lot of discussion among scientists.
Ultimately, Google’s breakthrough in quantum computing is unlikely to affect everyday use of computers, also because the machines cannot be reduced to handy devices due to the low temperatures and vacuum conditions required. Pichai writes that it is a “hello world” moment for the scientists that they have been waiting for. But there is still a long way to go between the laboratory results and practical applications of tomorrow . “It will be many years before we can implement a wider range of real applications.”
