What is Quantum Computing

Ian Hopper, Author

Quantum computing uses the laws of quantum mechanics to solve problems too challnging for normal computers to solve.

When scientists and engineers find problems too hard for themselvs to solve with their mindes, a pen and a piece of paper, they use supercomputers. But even supercomputers struggle to solve special kinds of problems.

If a supercomputer can’t solve the problem, it’s because the computer was asked to solve a problem that was too complex. When classic computers fail, it’s normally because the problem has lots of variables interacting in complicated ways. Modeling the behavior of individual atoms in a molecule is a complex problem, because of all the different electrons interacting with one another. And those are the kind of problems that quantum computers solve and watch and chart.

Quantum computers are made out of  QUBITS or (the quantum mechanical analogue of a classical bit) In classical computing the information is encoded in bits, where each bit can have the value zero or one. In quantum computing the information is encoded in qubits. A qubit is a two-level quantum system where the two basis qubit states are usually written as |1>’s and |0>’s. In other words, a normal computer uses bits where only a one 1 or one 0 can exist in the same place at one time while a quantum computer uses qubits where a 1 and 0 can exist in the same place at the same time, allowing for more complex information. And the machiene is just as complex. Just like any computer, a quantum computer is made of 3 main parts, memory which consits of the Quibits, a proscesser, and a input/output. But all of the components a bit more advancedd than a classical computer and of it all contributes to the understanding of particals and extreamly complex problems.
