Today, a piece of news is heating up in the foreign media:Google claims to have reached! The source of the news was the Financial Times, which reported that Google had claimed to have built the first quantum computer capable of surpassing today's most powerful supercomputer. This is a milestone and has been eagerly anticipated by researchers.

The Financial Times writes that they found a paper from Google researchers published earlier this week on NASA's website, claiming their processors.Can perform a calculation in 3 minutes and 20 seconds, and it will take about 10, 000 years to do the same with today's most powerful supercomputer, Summit..

The researchers say this means that quantum computers implementQuantum hegemony

The author of the paper wrote:The first calculation that can only be done on a quantum processo.

According to the researchers, the system can only perform a single, highly technical calculation, and it will take years to use quantum computers to solve practical problems.

But Google researchers call it(double exponential rate) development. Moore's Law promotes the development of silicon chips.

53 qubits, code name Sycamore

Startups from IBM to Rigetti Computing are developing so-called prototypes of quantum computers. Although prototypes of quantum computers have indeed been developed, they can only accomplish the same tasks as traditional computers, but only faster.

Quantum computers, if deployed on a large scale, will use properties that exceed classical physical limits to provide exponential growth in computing power.

A report by Boston Consulting Group in November 2018 suggested that quantum computers might.

Unlike the basic binary bits of classical computers, quantum bits or qubits can represent 0 or 1 at the same time. By stringing together quantum bits, the number of states they represent increases exponentially, making it possible to calculate millions of possibilities immediately.

Some researchers warn against exaggerating quantum hegemony, which, they argue, does not mean that quantum computers will soon replace traditional computers and bring about a revolution in computing.

The Google quantum team, led by experimental physicist John Martinis at the University of California, Santa Barbara, predicted for the first time that Google would reach quantum hegemony by the end of 2017. But Google's 72-qubit quantum computing system, released in March last year, still turns out to be too difficult to control.

Eventually, Google revamped the system and designed one.53 qubit system, code-named Sycamore. The task of the system is to prove that the random number generator is truly random. Although the work has little practical application, Google researchers say,

Steve Brierley, founder of Riverlane, a quantum software startup, says:

This really landmark development, but its paper quietly disappeared after the release, causing many netizens to suspect, excerpts from some comments as follows:

Cynic:

Cranky: Suppose you look at Google's paper and it disappears. Is it like a quantum chameleon? (That makes sense)

PM_me_your_balance: the paper argues that it does not exist because it overlaps. The behavior of downloading it for the first time crashes its fluctuation function, thus destroying the stack.

Neurodoc:, or the paper itself, like Schrodinger's cat, exists and does not exist at the same time (yes, not really quantum papers). Laplacian: sells all the encrypted currencies.
