Quantum computers coming. What's that mean to you? Yea, you shoud start thinking diffrent way on your privacy. First you shoud read article (link below), and beter protect your accounts, create stronger passowrds, and many more.

Don't panic, it is first step to quantum computer era. But it's also first alert to you. It's time to star prepare to new era in crypto space. Just read it and think.

Google’s quantum computer was able to calculate in 3 minutes and 20 seconds, for which the world's most powerful supercomputer, Summit (IBM), would take about 10 thousand years. Employees of the company outlined information about this scientific discovery in a publication that was posted on the NASA website. However, after a while, this report was deleted from the site without explanation. But the Financial Times managed to study and analyze the opening text.

At the end of August 2019, Google experts prepared a report entitled “Quantum Supremacy Using a Programmable Superconducting Processor” about their discovery using a new quantum computer - achieving quantum superiority. The material was published in September 2019 on the NASA website, but was later deleted. The data in this report remained in the Bing cache and is available at this link.

Quantum superiority is a turning point in which a quantum computer can fulfill a task that was previously considered impossible or would have taken an incredible amount of time to solve using the current advanced technological achievements of civilization.

A quantum computer is a computing device that uses the phenomena of quantum superposition and quantum entanglement to transmit and process data. A quantum computer (as opposed to an ordinary one) operates not with bits (capable of taking either 0 or 1), but with qubits that have both 0 and 1 values. Theoretically, this allows us to process all possible states at the same time, achieving significant superiority over ordinary computers in a number of algorithms.

Many companies and universities around the world are involved in the creation of quantum computers, but Google has been the leader in this race for several years.

As early as 2017, engineers at Google’s quantum hardware division used a 22-qubit quantum computer.

Google's quantum processors are located in the company’s lab in Santa Barbara. There they are kept in special tanks - cryostats. Compressed helium and liquid nitrogen, pumped from the freezer, cool the inside of the cryostat to minus 273.11 ° C. Such a low temperature is necessary to maintain superconductivity.

In fact, this is a quantum integrated system, which includes in addition to a cryostat with qubits and classical electronics, which is responsible for the remote access of specialists to the system for program research and analysis of the data obtained. Moreover, all elements of the system must be reliably protected from mutual and external interference.

This is a complex and expensive system for conducting quantum computing, and the company spends a lot of money on its maintenance and operation.

The quantum engineering team at Google is led by Hartmut Neven. Neven at the company previously oversaw the most innovative projects - from AI facial recognition software to launching Google Glass.

At the end of 2017, the Neven team in Southern California was preparing to launch a quantum computer on a 49-qubit processor, using which it was planned to overcome a new technological frontier, after which quantum computers could achieve quantum superiority.

In March 2018, Google introduced the 72-qubit Bristlecone quantum processor.

The company is also working on the creation of a new architecture for a quantum computer so that it is possible to work with it at higher temperatures, as well as using new engineering solutions to reduce interference during data transfer.

And so, in September 2019, Google experts published a report on their discovery when using a new quantum computer - achieving quantum superiority.

A Google quantum computer with a 53-qubit processor, called the Sycamore (Platan), took part in a scientific experiment. To create Platan’s infrastructure, the Google quantum technology team even had to downgrade the design of the previously created 72-qubit Bristlecone processor.

NASA’s website, removed for unknown reasons, claimed that Google’s quantum computer was able to perform very complex software calculations in just two hundred seconds. Thus, an experimental demonstration of the superiority of a quantum computer over a traditional one was carried out.

For comparison, Summit's most advanced supercomputer could produce such a result in only 10 thousand years. The Summit supercomputer was launched in the United States in 2018. Its estimated capacity is 200 thousand trillion operations per second, it consists of 4608 computing servers, each of which has two 22-core IBM Power9 processors, and internal memory reaches 10 petabytes.

Also, according to company experts, the implementation of the same experiment on a Google Cloud server would take 50 trillion hours (5.7 billion years).

In their publication, Google experts clarified that their new system can only perform one calculation, and the use of quantum computers to solve practical problems is in the distant future.

Whether this calculation was associated with certain studies or mathematical problems, the company did not specify. Although the company’s specialists explained in the article that the experiment used random numbers generated according to a special scenario associated with quantum phenomena.

“We have achieved significant acceleration compared to all known classical algorithms, which was able to provide experimental implementation of quantum superiority in the solved computational problem, which marks the emergence of such an expected computational paradigm,” the Google report stated.

The report also suggested that the power of new quantum systems would increase at “double exponential speed,” even ahead of the exponential speed that determined Moore’s law, a trend in which traditional computing powers double approximately every two years.

Regarding the removal of the publication from the NASA website - Google refused to confirm the authenticity of the report and its results, NASA also did not respond to a request for comment about this strange removal of material from the publication.

However, according to Fortune, a source at Google familiar with the situation suggested that NASA accidentally published this document too early.

After all, the calculation results and analysis of the quantum computer calculations have yet to be thoroughly checked by experts and scientists. And such a process of complex scientific peer review can last from a few weeks to months. Also, this article will be under the scrutiny of the scientific community, and if its results are confirmed, it will become a harbinger of a turning point in quantum science.

Why were the data on this experiment published on the NASA website? In 2018, Google entered into an agreement with NASA to use the agency’s supercomputers to verify the company's calculations using quantum computers.

In general, no matter what the results in Google’s calculations, many quantum technology developers fear that the current results of the experiment may be exaggerated and they are worried by the fact that increased expectations of imminent progress in this area in the short term will lead to the emergence of a new technological a bubble that can burst quickly.

Dario Gil, director of IBM Research, does not recommend using the term “quantum superiority” as a metric to measure progress in this area. “This experiment and the term quantum superiority will be misunderstood by almost everyone,” Jill cautioned. According to him, it was a special laboratory experiment, which at the moment has no practical application.

“Quantum computers will never dominate classical computers, but will work with them, because each has its own unique advantages,” said Jill.

Jim Clark, Intel Labs Director of Quantum Technology, identified Google’s achievement as a significant marker in the development of quantum computers. However, according to him, a commercially viable quantum computer will still require many achievements and solutions in the field of R&D before it becomes a reality.

“Despite the fact that this development is still at the first stage of our marathon, we firmly believe in the potential of this technology,” Clark added.

That's good because it will certainly be very helpful in many ways, but indeed we have to be more careful because behind something new there is certainly also a new danger.
