Quantum computing spreads across a wide range of disciplines both on the hardware research and application development fronts, including elements of computer science, physics, and mathematics.

The goal is to combine these subjects to create a computer that utilizes quantum mechanics to solve complex problems faster than on classical computers.

A quantum computer processes quantum states; these are units that can be thought of as being both zero and one at the same time.

With this model, quantum computers could be faster than traditional ones with regards to a few known tasks: unluckily, the two main tasks which quantum computers are good at are factoring large numbers and solving so-called discrete logarithm problems.

The advent of a quantum computer and its effect on cybersecurity and data privacy is often dubbed the "Quantum apocalypse".

The first uses the physics of quantum mechanics itself and is called Quantum Key Distribution.
