The reality of quantum computers

The reality of quantum computers

Quantum computers are being named these days for making great strides in its development and is probably not knowing much about quantum computers and what it represents for the future of computing and computer systems. Quantum computers set aside the logical systems used by today’s computer systems and use the atom states model to perform their processes.

Conventional computers summarize all information that processes binary language; they only use two states for data: 0 or 1. As if a switch was involved, the bits can only be turned on or off.

The atoms in quantum computers

Atoms have a curious quality, which is precisely one of the properties that make quantum computation incredible, this quality is superposition. The superposition of the atom consists in that an atom can adopt a state of 0 and 1, but it can also adopt both states at the same time. These quantum computers are able to test at the same time all the possibilities that exist for the concrete solution of a problem, instead of testing all the possibilities one after another as they are realized at the moment.

This change in the paradigm of computing is a huge leap forward in computing power, which would allow complex computations that are currently unattainable even for supercomputers.

The power of quantum computers, like that of conventional computers, is measured in processing units, which are no more than individual atoms. In the case of quantum computers, it is measured in quantum bits or qubits. The more qubits, the faster they work.

The atoms, besides being able to adopt several states simultaneously, count on another peculiarity called atomic entanglement. This allows creating quantum interlacing’s between several atoms so that they create a network of atoms that work in a harmonic way. We could say that they are like cores that work together in a conventional processor, but at a much more complex level.

IBM to build first Quantum computer

IBM is taking steps to make quantum computers a reality. It will build the first quantum computers that will have commercial use and can be applied in business and science. The IBM Q, which is what the new systems will be called, will outpace the most powerful current supercomputers in speed and computing capacity, according to the company.

IBM Q systems and services will be distributed through its cloud platform, although the firm has not yet disclosed when they will be available.

IBM spokespersons explain that while technologies currently running on classic computers, such as their Watson cognitive system, can help find patterns and ideas buried in large amounts of data; quantum computers will offer solutions to problems where patterns cannot be seen because the data does not exist and the possibilities that need to be explored to arrive at the answers are enormous.

As a first step in increasing quantum volume, the firm will develop commercial quantum QMs over the next few years and collaborate with key industry partners to develop applications that exploit the quantum velocity of systems.
