Quantum computing is a complex approach to parallel computation that uses the physics that drives subatomic particles to replace today’s computers’ simpler transistors. Instead of regular computers’ bits, which are either on or off, one or zero, quantum computers use qubits, computing units that can be on, off, or any value in between. The capacity of the qubit to exist in an in-between state, known as superposition, adds a powerful feature to the computing equation, making quantum computers superior for certain types of math.
What Is the Purpose of a Quantum Computer?
Quantum computers, using qubits, might whiz through computations that would take classical computers a long time – assuming they could even finish them.
Today’s computers, for example, employ eight bits to represent any integer between 0 and 255. A quantum computer can use eight qubits to represent every integer between 0 and 255 at the same time, thanks to features like superposition. It’s similar to parallelism in computing in that all possibilities are processed at once rather than sequentially, resulting in huge speedups.
It, whereas a classical computer must perform long division calculations one at a time to factor a large number, a quantum computer may do so in a single step. Boom! That means quantum computers could change entire fields based on factoring what are currently impossibly big numbers, such as encryption.
