The second day after the old rival IBM shelled, the silent Google finally re-voiced!

According to Xinhua News Agency’s October 23 news, Google’s “Quantum Hegemony with Programmable Superconducting Processors” paper was published in the British “Nature” magazine in the form of a heavy cover, indicating that it has successfully demonstrated “quantum hegemony.” “It takes about 200 seconds for the quantum system to complete the task that the traditional supercomputer will take 10,000 years to complete.”
“In the eyes of the Google team, this is a milestone in the quantum field like “Hello World.” Google CEO Sundar Pichai was excited to introduce the MIT Technology Review. It was like the moment when the plane was first invented—the Wright brothers’ plane flew for only 12 seconds for the first time, but he proved the possibility of the plane flying.
“Quantum hegemony” has long been used to describe the key nodes in the development of quantum computers. It refers to quantum computers that can solve the complex problems that traditional computers cannot solve, that is, to show quantum superiority. And this is a key step in the practical application of quantum computers. Among them, an important indicator that is often regarded as quantum hegemony is the number of qubits. Some scholars believe that quantum computers can achieve “quantum hegemony” by about 50 qubits.
The advantage of quantum computers is that traditional computers are not zero or 1 per bit. In quantum computers, quantum bits can be in a quantum superposition state of 0 and 1 , which makes quantum computers unimaginable by traditional computers. Super computing power. For example, a 10-qubit quantum computer can process 210 or 1024 possible inputs at a time.

According to Xinhua News Agency, Google research team developedA processor consisting of 54 qubits, “Sikmo”, actually uses only 53 qubits because one qubit does not work effectively. The team designed a task to sample random numbers generated by quantum circuits. In the experiment, the quantum processor collected 1 million samples from the quantum circuit in about 200 seconds, and a cutting-edge supercomputer took about 10,000 years to complete the task.
Before this Google “quantum hegemony” paper was officially published, the old rival IBM made a public bombardment. Google’s “quantum hegemony” was flawed. The result of simulating Google’s computer on a classic computer only took 2 and a half days. It doesn’t last for ten thousand years. They believe that the threshold for “complete the work that cannot be done by traditional computers” has not yet been reached.
And Google is surprisingly silent. Until October 23, Sanda Picha publicly responded in the media: “The point of controversy is whether quantum computers will replace classic computers as many people think. This is similar to the progress people have previously celebrated on AI, Google published The results explain our research and help people better understand how far we are from general-purpose quantum technology.
Some analysts believe that quantum computers will never achieve “hegemony” beyond traditional computers, but will cooperate with the latter, because each has its own unique advantages.
Talking about the future application value of quantum computers, Sanda Pitch said: “For example, to help scientists find more efficient battery design solutions, wherever chemical is concerned, quantum computers can come in handy.” It is also the driving force that Google has invested in for 13 years and will continue to study in the future.
