IBM Gets Sniffy at Google's Quantum Supremacy Claim


Google announced Wednesday it has achieved a breakthrough in quantum computing, saying it has developed an experimental processor that took just minutes to complete a calculation that would take the world's best supercomputer thousands of years.

For those who don't know quantum eigenstates from The Eiger Sanction (and might, therefore, wonder whether quantum supremacy were a new Jason Bourne movie), both the Washington Post and New York Times offer engaging layman's explanations of the import of the quantum supremacy achievement.

Quantum computing is among the science and technology innovation projects listed in Beijing's current five-year plan.

Martinis said that Google saw "a pathway" to a computer with 1,000 qubits and expressed confidence that it had a reliable process to make its new chip, dubbed Sycamore. But the latest findings, published in the scientific journal Nature, show that "quantum speedup is achievable in a real-world system and is not precluded by any hidden physical laws", the researchers wrote. The corporate is racing rivals along with IBM Corp and Microsoft Corp to be the first to commercialize the technology and promote it through its cloud computing business.

The blog further says, "To our knowledge, this experiment marks the first computation that can only be performed on a quantum processor". 'The United States has taken a great leap forward in quantum computing, ' said USA chief technology officer Michael Kratsios on Wednesday.

Google has tested its new technology, and what they found is that technology Google's 54-qubit Sycamore chips took 200 seconds which is 3 minutes & 20 seconds to complete calculations that would take the world's fastest supercomputer 10 thousand years to finish.

It is comprised of a two-dimensional grid where each qubit is connected to four other qubits.As a outcome, the chip has enough connectivity that the qubit states quickly interact throughout the entire processor, making the overall state impossible to emulate efficiently with a classical computer. The computer harnesses some of the most mind-boggling aspects of quantum mechanics, including a phenomenon known as "entanglement" - in which two members of a pair of bits can exist in a single state, even if far apart. Pichai's analysis of the work, meanwhile, is available on the Google blog.

IBM said that a supercomputer with additional disk storage could solve the random number problem in at most 2.5 days and with greater accuracy.

China is now leading the way in the development of quantum computers for military use. "You can trace the progress from the mega-computers of the 1950s to advances we're making in artificial intelligence today to help people in their everyday lives".

"Clearly, we're in a position that as we demonstrate promise, we would be attractive to 'a Google, '" Quantum Computing CEO Robert Liscouski has said. The Quantum computers are not similar to the desktops or laptops, these are present in separate parts that are present in the server room. 'Universities, governments and technology companies around the world are striving to achieve a commercially-viable quantum computing system.
