Could this simulation be possible with Quantum Computers?

Some of the very special tasks as we know require some cracking of  'brain' from our machines, which these days come with diverse sophistications. I use my normal classical machine (Laptop Computer) to type this article and do some other works meant for this type of machine, which processes data in 1s or 0s, can do some pretty fast calculations per second, and other great stuffs, there are things its not meant to do. 

That's where we will be talking about Quantum computers and some simulation that scientists are working towards achieving with this machine. Before we go into what the simulation is, let us look at what this quantum computer is all about and some stuffs it can do, quantum computer built by the D-Wave for example is one of the most advanced quantum computer in the world, based on a novel type of superconducting processor that uses quantum mechanics to massively accelerate computation. 

Now this machine, rather than stor information as 0s or 1s as mentioned above, a quantum computer uses qubits, this can be a 1 or 0 or both at the same time, which along with quantum effects of entanglement and quantum tunneling, enable quantum computers to consider and manipulate all combinations of bits simultaneously, thus making quantum computation very powerful and fast. This computer though is best suited to tackling complex optimization problems.

Scientists have discovered that simulation of virtual particles can be done with the help of quantum computers, according to research, it cold help explain more on currently hidden aspects of the universe, from the hearts of neutron stars to the very first moments of thye universe after the big bang. 

Now interactions between elementary particles are often described with what is known as guage theories, but getting real-time dynamics of particles in guage theories are extremely difficult for the classical or conventional computers to compte, except in the simplest cases, which is where quantum computers come into play according to research. 

These quantum computers were made to simulate the apperance and disappearance of virtual particles in a vacuum, with pairs of qubits representing pairs of virtual particles, electrons and positrons. 
According to the scientists experimenting on advanced simulations using qantum computers, quantum computers can simlate high-energy physics, showing how particles might behave at energy levels that are much too high to be easily generated on Earth. For more visit livescience.com .
