Superfast Quantum Computers Will Soon Become Reality

A team of researchers from the University of New South Wales have built a quantum logic gate in silicon. It is considered a game changer in creating quantum computers.

Scientists have reached one step closer to creating quantum computers which will be more fast and powerful than existing ones. 

A team of researchers from the University of New South Wales has cleared what could be considered the final hurdle in making the superfast quantum computers. They have developed a quantum logic gate in silicon for the first time and are calling it a “game changer” in terms of making mind blowing computers of the future.

“We've demonstrated a two-qubit logic gate - the central building block of a quantum computer - and, significantly, done it in silicon.” said Professor Andrew Dzurak, Scientia Professor and director of the Australian National Fabrication Facility at UNSW. 

“Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs, which rely on more exotic technologies.”

Computers require bits to store the information. In modern day computers, the binary bit has a value of either state 1 or 0. However, in a quantum computer, a bit or qubit can encode multiple states at the same time and could perform multiple calculations on different states of quantum bits simultaneously. This complex will be the fundamental new building block of the future computers, not just a simple one or zero.

The key thing is that silicon chips in our mobile phones, tablets and conventional computers have transistors. All we need is to turn those transistors into quantum bits by reconfiguring them and associating an electron with them.

“This makes the building of a quantum computer much more feasible, since it is based on the same manufacturing technology as today’s computer industry.” Dzurak said.

If these computers are developed, they can help search large databases; solve complicated equations and to model atomic systems.

“Quantum computing promises processing speeds that seem unimaginable by today’s standards,” said Mark Hoffman, a professor at UNSW. This is “the kind of quality, world-leading engineering advance that we need — as a society, as an economy, and as a country — to believe in, to invest in and to support.”

The study was published in Nature.
