What is Quantum Computing?

In classic computers we understand the data to be binary and present at a bit level. The data is built by small switches that are present in either an on or off mode, often described by a one or a zero.

Quantum Computing changes that fundamental principle, meaning that data will exist in both states at once and every possible state surrounding it. Quantum Computing breaks down the two options of on or off into a list of exponential possibilities available as a resource. This creates quantum bits, referred to as Qubits.

Each Qubit now has the power to operate as an individual processor and memory more powerful than an entire classic computer.

The power of a Qubit is both significantly impressive and important for the future of information technologies. As a direct comparison, in 2019 a Quantum Computer built by Google managed to perform a calculation in less than 4 minutes that would take a modern-day supercomputer 10,000 years to complete.
