Google Is On The Verge Of Producing A Working Quantum Computer

For a long time, the tech industry has relied on supercomputers to perform tasks which personal computers (PCs) could not. But years of research at Google AI could deliver a super supercomputer in just a matter of months.

Double exponential growth rate of computational power

Google AI is working on a computer chip which should be able to perform computations beyond the ability of regular computers. The research has been able to develop a chip whose computational power builds quicker than that for classical computers.

For starters, classical computers grow their computing power exponentially, what is referred to as Moore’s law. But the new chip from Google AI is something else.

Hartmut Neven, Google AI lab director, explained at a Google Quantum Spring Symposium that this new chip is gaining computational power compared to regular computers at a rate which is doubly exponential.

“It looks like nothing is happening, nothing is happening, and then whoops, suddenly you’re in a different world. That’s what we’re experiencing here,” Neven said.

Quantum computers

Regular computers use bits to communicate digitally. On the contrary, quantum computers make use of quantum bits or what scientists call qubits. The difference between traditional bits and qubits is that qubits have quantum properties. Basically, this is to say that qubits can exist in a dual state, better known as superposition.

Classical computer bits exist in ones and zeros. Therefore, there are two states. On the contrary, qubits can acts as zeros and ones simultaneously, a property which speeds up computations.

Existing research was of the view that quantum computers are exponentially faster than classical computers. This is to say that every new qubit speeds up the computer exponentially. However, Neven and his team has been able to show that the processing power of a quantum computer is far much faster.

Therefore, the traditional Moore’s law has been replaced with Neven’s law which explains the rate at which quantum computers gain computing power over classical computers. This new law means that manufacturers will be able to speed up computers rapidly at a growth which is unseen in nature.
