Quantum Computing: Explained

 

If you will ask any expert, he will say that quantum computers are the next logical step in the evolution of computing. In this article I will walk you through what this new technology brings to the table and how useful it all is, but first let`s get down to the unit.

In basic computer, the memory is made up of bits, where each bit represents a one or a zero.  On the other hand, in a quantum computer, the memory is made out of qubits, where now, each quit can represent a one or a zero or both of them at the same time. This will make a lot of difference, as a classical computer with n bits can represent only n states. To put this in perspective a quantum computer can represent 2n states.

All sounds great, but some problems need to be solved in order to even get one working. One of those problems is Quantum decoherence, or the loss of coherence of ordering of the phase angles between the components of a system in a quantum superposition. In short form, Quantum decoherence is the interference of waves that degrades the quality of the end-result.

Considering all the problems it may rise, a quantum computer is exponentially faster than a classical PC, but you won`t benefit a lot from that, at least for the time. This speed isn`t necessary for games of basic video production or photography. This speed will only benefit the researchers. I`m talking about doctors, physicians or any other type of researhers. This will hopefully bring faster advances in physics and medicine, and maybe sometime soon, cancer will not be a problem anymore.

In conclusion, a quantum computer is a faster type of computation device, that bring a lot of new technology to the table and will, hopefully, make research faster.

My name is BMC and I am a superhero. Well, maybe not a superhero, but what is certain is that I am an aspiring writer with high hopes and big dreams. I started writing in the summer of 2013 on this website and let me say, it is a fantastic ride!
