Quantum computing is a situation where computers are able to work via superposition. Quantum computers function with particles in superposition and instead of representing bits, they will represent qubits.

The qubit can easily take the value of 0 or 1, or take up both positions simultaneously. Quantum computing will take advantage of subatomic particles’ ability where they are able to be in multiple states at a time. This will make the operations much faster and in the end, less energy will be used in the operations.

Quantum computers do not follow normal physics rules. Instead, they will use qubits and will be extremely fragile when using them. They will also require a lot of infrastructures to make them operational which means they will be more complicated.

Quantum computers work through:

**Parallelism:** this will allow a quantum computer to carry out a million computations at the same time. While regular computers are only able to work at a speed of billions (gigaflops) floating-point operations per second, a quantum computer will work at trillions (trillions) floating points each second.

**Entanglement:** it is easy to bump the subatomic particles in quantum computers which will change their value. This makes a qubit either assume the value of 1 or 0 which will create the possibility of having correct and wrong conclusions.

With the use of quantum computers, it will be possible to find cures for complex health complications, engage in space travel, and even predict the weather. It will be easy to solve complex mathematical problems fast.

There are reports that quantum computing will be more secure and this will make it harder to hack. Before this happens, however, there will be a disruption in the operations of the regular computer.

Google is among the companies that are working towards making quantum computers a reality. Though more needs to be done, there are huge steps that have been taken to make quantum computing a reality.
