For the first time ever, Google’s quantum computers have performed an arithmetic task that cannot be completed with traditional computers.
Scientists and engineers at Google Lab in Santa Babra have announced that there is a super stage they have never reached before. A quantum computer has completed its mission in just 200 seconds while conventional computers can complete the same task in 10,000 years.
The task itself involves carrying out a series of instructions, and has no practical application in a specific field, but scientists say that the achievement is still important as evidence of the progress of quantum computing technology.
Google’s administration and scientists praise the achievement, and consider it the first display of what is called quantum excellence!, a term coined by John Priestel in 2012 to describe the stage in which quantum computers do things that ordinary computing devices cannot do.
Not everyone agrees that Google’s announcement represents a true quantitative advantage. IBM’s scientists responded to Google. They denied the term and said the computer could complete the task in two and a half days instead of 10,000 years.
Google’s success may be noteworthy, Brescell said, it will not change overnight, but it is important that quantum computers advance and evolve performance, and outperform traditional computers.
John Preskill spoke to a reporter about the position of quantum computing today, and what kinds of big problems might help us solve them in the future. Here are some questions:
How did you become interested in quantum computing?
In the mid-nineties of the last century, I discovered that if there was a quantum computer, we would be able to solve some difficult problems, we can have the possibility to break the widely used coding systems, which was expected not to be broken because it requires calculations Very difficult.
How does the quantum computer differ from a simple conventional computer?
The language spoken by classical computers revolves around processing strings of 0 and 1, but the language of quantum physics is completely different, it relies on qubits that can be stored as 0 and 1 together at the same time.
What kinds of problems quantum computers solve?
When the applications are more obvious, then you will have to know how a large quantum system behaves, for example, chemists try to accurately describe what happens when trying to build a large molecule.
They try to apply this to computers, but when the molecule becomes large, it is difficult because quantum mechanics is really important in the molecule, and you cannot describe what normal bits do, but quantum computers can be described well.
Does it have apps in the real world?
We believe it will have a significant impact on quantum chemistry, which may be important in the fields of agriculture and health, and can help in developing new drugs, new energy sources and new ways to collect solar energy and new materials.
Are scientists currently using quantitative solutions to solve problems?
People are experimenting it, but there is nothing amazing to disclose, I don’t think anyone has done anything big with quantum computing, traditional computers do what we want now.
What prompted you to formulate the term “quantitative advantage” in 2012?
I suggested that I think of this term when I noticed something special in the history of technology, with the advancement of quantum computing, we will get to the point where we do things with quantum computers that we think are beyond what we can do with our regular computers.
Not everyone loves this term, right?
Some people believe that the term inflames the state of existing technology too much and gives unjustified and unrealistic expectations of what the effects will be in the short term. We are in an age when we have powerful computers and we do not know what to do with them, we have to try it differently and in different fields.
Do you think google announcement is a big problem?
This depends on what you think is a big deal, it is a gradual step, but we may rest and rely on it as evidence of the advancement of quantum computers technology, and it could be a springboard for the better.
Do you think quantum computers will one day be the standard?
Based on our current understanding, quantum computers will have a very specialized applications, but that will be far-reaching for now, but the day will come when you check your email on a quantum computer!
But in reality, it is not crazy to say that from the future, we may have a quantum internet that sends quantitative information because that has coding advantages and it is very difficult to eavesdrop on this information encoded information in quantum cases.
This post gives a nice understanding, Thanks !
