We are confident that once quantum computers with tremendous computing power, are to replace conventional computers, which at that time would be an anachronism. The new quantum simulator, developed by scientists from the University of Sydney, has the "potential that could perform calculations that would require power supercomputer with a size greater than the size of the known universe."
Quantum computers are due to the effect of quantum superposition, which means that each quantum bit (qubit) can be equal to both one and zero. This is quite different from conventional computers, the bits of which can only be in one of two possible states. And if you remember anything about the exponential curves, you can imagine how much more calculations can produce a quantum computer with a certain number of quantum bits compared to conventional computer with the same capacity.
Sydney researchers say they were able to implement a new type of quantum computer on a chip, which are 300 quantum bits. This bit quantum processor means that hypothetically such a computer can execute simultaneously operations. For comparison, if you take every atom in the known universe, and turn it into a bit of a classical supercomputer, then all the atoms is not enough, that to reach the computational power of a quantum computer with a 300-atom qubits.
Of course, quantum computers are currently still highly specialized tools. Sydney's new quantum computer will act as a "quantum simulator", which will be carried out mathematical modeling of different quantum systems, which is absolutely impossible to do using conventional computers, even with the prefix "super." For example, a quantum computer can perform simulation bude interaction quantum rotating magnetic field, which could eventually lead to new discoveries and the acquisition of new knowledge in the field of high-temperature superconductivity in the transformation (transformation) of some types of energy to another and to develop " entirely new forms of quantum matter.
