Quantum Computers: Getting Closer To Become A Reality


Computers might have more calculating and processing power than its inventors and developers but the latter are not in a mood to bank the stream at all. To satisfy our appetite of greater processing speed physicists are working on quantum computers.

Quantum computers, unlike the digital transistors in microchips, will use quantum particles having the ability to store and manipulate data. Like all other computer systems nowadays, these computers will also use bits but extraordinarily different from the ones in use already. Phrased as Quantum bits or “qubits”, they will have the capacity to be “one” and “zero” at the same time.

A team of Physicists at Rice University have covered another milestone in the development of such particles. According to a research paper published recently, physicists claimed to have developed a device called “Quantum spin Hall topological insulator”. It is prepared from a commercial grade semiconductor also being used in manufacturing goggles for night vision. It acts as an electron super highway and boasts primary importance in the development of quantum particles.

According to experts at Rice University, these particles will prove their worth in accelerating the processing speed of computing tasks related to code breaking, climate modeling and bio modeling simulations. To add more to your astonishment only 30 qubits alone can take over the job of 1 billion digital transistors.

The challenge faced by the scientists working on quantum computers is that of the apprehension of losing the information stored on qubits due to the quantum fluctuations. To overcome this fear, innovators in Rice have come up with idea of “topological quantum computing”.

These computers will be built from a pair of quantum particles with incontrovertible shared identities. All attention is now being given to the invention or observation of a stable version of such a pair named “Majorana fermions”.

Being proposed more than eighty years ago already, Majorana fermions are now tried upon to be created in a chip. Topological insulators spare the electricity to flow through its not-so-wide outer edges only.

Kenz, a physicist at Rice, expects that Majorana fermions particles can appear on the insulator as soon as it is contacted with a superconductor, and on the precise point on which they meet. According to him, if this proves true, the qubits can be produced by using the topological insulator.

The men pledged to experimentally prove the worth of Majorana fermions for creating stable qubits.
