What is Google’s Quantum Computer Revolution And How Can It Change The World?

2 min read

Google’s successful quantum computer trial has leaked into the Internet. It shows that we’re close to answering the biggest questions in the universe.

According to a research paper, a calculation that could not be performed even by the most powerful supercomputers was achieved thanks to a revolutionary new type of computer.

The article argues that researchers working on one of the tech giant’s quantum computers have achieved what is called quantum supremacy, and thus herald a new era of computing power that is not comparable to its predecessors.

In the experiments of researchers, a calculation just took 200 seconds to perform by Google’s quantum computer. This calculation would be approximately 10 thousand years by a standard supercomputer. The article contained the following statements:

To the best of our knowledge, this experiment is the first calculation that only a quantum processor can perform. This was a calculation known as the “random sampling problem” that checks whether a very large set of numbers is really random and proves that for now, only quantum processing can work. Although there are not many direct applications of determining which numbers are random, this form of processing may have future effects that change the world.

What is a quantum computer?

The quantum computers, firstly theorized by physicist Richard Feynman in 1982, are essentially differentiated from classical computers by means of data transfer and storage.

Unlike conventional computers, quantum computers use qubits (quantum bits) instead of using binary numbers, namely “1” and “0”.

The cubits are in a state called a superposition, which means they can act as both “1” and “0” at the same time.

In this way, the addition of each qubit to quantum computing systems makes the quantum computer exponentially stronger than conventional computers.
