Breaking: Google achieves ‘quantum supremacy’

[F-22Raptor]

Google has reportedly built a quantum computer more powerful than the world's top supercomputers. A Google research paper was temporarily posted online this week, the Financial Times reported Friday, and said the quantum computer's processor allowed a calculation to be performed in just over 3 minutes. That calculation would take 10,000 years on IBM's Summit, the world's most powerful commercial computer, Google reportedly said.

Google researchers are throwing around the term "quantum supremacy" as a result, the FT said, because their computer can solve tasks that can't otherwise be solved. "To our knowledge, this experiment marks the first computation that can only be performed on a quantum processor," the research paper reportedly said.

Google declined to comment on the FT's report.

The tech giant unveiled its 72-qubit quantum computer chip Bristlecone in March 2018, saying at the time that it was "cautiously optimistic that quantum supremacy can be achieved with Bristlecone."

Quantum computing, which can simultaneously evaluate multiple possibilities, will likely be used for physics and chemistry simulations that aren't possible with classical computers, which can't simulate complex chemicals. They could also create new drugs and solar panels, help develop artificial intelligenceand self-driving cars, and even manage investment portfolios.

Earlier this week, IBM unveiled its 14th quantum computer, which has 53 qubits. It'll be available for quantum computing customers in October.

AT&T also recently said it's working on quantum networking, or the technology to link quantum computers.

Google's Quantum computer. This single little chip can beat a gigantic supercomputer that takes up the entire floor of a building.

It's like this all over again.

Just another of the thousands of breakthroughs the US has brought mankind.

A guaranteed Nobel Prize

What about the 10's of millions of people you guys murdered? and countless countries you destroyed.. are All Americans this narrow minded..

Nobody’s perfect. Besides when you fly in a plane or zip up your coat or use some other US invention you don’t even think about it. You just go about your day enjoying life’s little pleasures. As if you remember to thank us for them...

The compute power is mind boggling - hopefully Sunder and co will come up with good developmental problems for it to solve. Should also ensure the technology is not stolen

'murica is the most uncivilized place on earth. Google is going to use that technology to spy on and harass average ordinary Americans.

Murica is like a genie with a gun, the only thing they know to do is kill people with the gun.

China is using their technology to better the lives of the Chinese people because China cares about the Chinese people. In Ahhmurica, every knowledgeable citizen is the enemy of the state.

The intelligent are not wanted there.

BTW, who are training genies to think? Clean up on aisle 3.

How significant is this milestone? Very. In a discussion of quantum computing at MIT Technology Review’s EmTech conference in Cambridge, Massachusetts this week before news of Google’s paper came out, Will Oliver, an MIT professor and quantum specialist, likened the computing milestone to the first flight of the Kitty Hawk in aviation. He said it would give added impetus to research in the field, which should help quantum machines achieve their promise more quickly. Their immense processing power could ultimately help researchers and companies discover new drugs and materials, create more efficient supply chains, and turbocharge AI.

Long way to go but its a breakthrough in quantum computing!

Google Says It's Achieved Quantum Supremacy, a World-First: Report

A Google researcher’s paper claiming to have achieved quantum supremacy, a major early milestone in the field of quantum computing, appeared on a NASA website this week before being removed, the Financial Times reports.

Google, as well as IBM, Microsoft, Intel, and other large tech companies and startups, have been working to build quantum computers, a new kind of computer based on an entirely different architecture than classical computers. Though this announcement is not official, scientists and industry experts have long expected Google to build a quantum computer capable of reaching this milestone—a quantum computer performing a calculation that a classical computer can’t.

You can read our primer on quantum computers here and our primer on quantum supremacy here. But the gist is, classical computers are systems where problems are abstracted onto a system of two-position switches called bits (ones and zeros) that interact through the rules of logic. Quantum computers are instead based on quantum bits, or qubits, that are also two-position switches, but they interact via the same rules that subatomic particles follow, called quantum mechanics.

This quantum architecture purportedly could allow quantum computers to solve a set of problems that classical computers can’t in a reasonable amount of time—this includes problems in cryptography as well as modeling molecules. But the difficulty maintaining qubits’ quantum behavior for a usable amount of time, also called the coherence time, has prevented researchers from demonstrating any sort of quantum speedup.

The Financial Times reports that they saw a Google publication claiming that the company’s quantum processor can perform a calculation “in three minutes and 20 seconds that would take today’s most advanced classical computer, known as Summit, approximately 10,000 years”—a demonstration of quantum supremacy. Google has not yet responded to a Gizmodo request for comment, and it has long been cagey about when and how it’d make the announcement.

We don’t have many details as to what calculation the computer performed, nor can we independently verify the Financial Times report. But previous proposals essentially involve the quantum computer racing a classical computer simulating a random quantum circuit. The achievement would not be a surprise—we’ve long known that Google has been testing a 72-qubit device called Bristlecone with which it hoped to achieve quantum supremacy. Financial Times reports that the supremacy experiment was instead performed with a 53-qubit processor codenamed Sycamore.

This would be a major early milestone when it comes to comparing these quantum devices against classical computers. But we’re a long way off before quantum computers actually demonstrate quantum usefulness. That would require increasing the coherence time and introducing error correction schemes‚ those where multiple qubits are combined into one in order to ensure that the quantum computer outputs the answers it’s supposed to output.

“Google’s recent update on the achievement of quantum supremacy is a notable mile marker as we continue to advance the potential of quantum computing. Achieving a commercially viable quantum computer will require advancements across a number of pillars of the technology stack,” James Clarke, Director of Quantum Hardware at Intel, told Gizmodo in an email.

It’s possible scientists may not even accept Google’s announcement as valid. Most importantly, if it takes 10,000 years for a supercomputer to check the answer a quantum computer produced, how do you know that the quantum computer got the answer right in the first place?

We’ll keep you posted as we learn more about the reported paper.

Congratz, google and USA.
We will benefit from it in a few years down the line. Together with 5g I see lots and lots of potential.

If the paper holds up under the scrutiny of the scientific community, it will herald a watershed moment in quantum science. Its central claim counters doubt that some unforeseen law of nature may prevent quantum computers from operating as hoped.

“Quantum speedup is achievable in a real-world system and is not precluded by any hidden physical laws,” the Google researchers write.

Further, they predict that quantum computing power will “grow at a double exponential rate,” besting even the exponential rate that defined Moore’s Law, a trend that observed traditional computing power to double roughly every two years.

This is amazing!

I wonder whatever the computer can run under room temperature?

Or it's just in the lab under special environment?

Its definitely in a lab environment. There’s a lot of technological advances that need to be made to have a viable commercial quantum computer.

But this is definitely a breakthrough!

Liquid nitrogen for sure.
