  • Google gets Ready for Quantum Computing

Google is known for its moonshot. Today it is getting ready for quantum computing which is the top item on its agenda.

For the past three decades, many research think tanks have tried to construct a universal quantum computer from scratch. The project has been in the making and it is nearing completion today. Especially, the big daddy of search engines (that would be Google) seems to be in on the game.

A quantum computer would be able to solve any computational problem in a jiffy. A team of researchers from California and Spain have made a scaled-down version of the device. The gadget will have applications in the fields of chemistry and physics.  

It can be taken up several notches so that the quantum computer is actually a full-fledged gizmo. Also IBM and D-Wave have made inroads into making a quantum computer.

At Google’s lab the research is being carried out at a breakneck speed. The novel device they have come up with is a wonder to behold. The work that is going on in all these think tank agencies is a beautiful beginning and it will have great results in the future. Quantum computing is the next wave that will literally touch tomorrow.  

The Google model of a quantum computer contains two different approaches. One involved the constructing of the digital circuits in qubits in various arrays in order to solve a particular problem. This follows the classical model of ordinary run-of-the-mill computers.

Quantum computing is normally done through this old school methodology. Yet there is another approach too. This is the analog design. Termed adiabatic quantum computing (AQC) it involves the encoding of a given problem in the form of a group of qubits. Then their evolution takes place shaping their behavior along the way. Thus a solution to the problem is finally reached. 

The only problem with this analog approach is that it is limited by the interference of random noise. The resulting errors cannot be rectified so easily. Also there are glitches having to do with efficiency in the system.

However, AQC is the only chance humanity has of sealing the quantum deal. Any commercial devices that will be made in the future will have AQC as a fundamental part of their makeup. Google is at the forefront of making such a device. Google’s lab team used a row of nine solid-state qubits. They were made from aluminum films.

Deposited on a sapphire surface, the aluminum films are cooled to 0.02 degrees kelvin. This results in a superconductor and the information can be encoded into the device. The rest is all a tangle of logic gates and complex quantum mechanics that cannot be gone into here. Suffice it to say that like the calculator is to modern day computers, so will the computers of today be to quantum computers which will rule the roost in the future.
