Quantum computers work based on the principles of quantum mechanics. This is a branch of physics that describes how tiny particles behave. Bits used in regular computers can only be ‘0’ or ‘1’. However, Quantum computers use qubits (Quantum Bits), which can exist in multiple states simultaneously. This is called superposition.
Qubits are unique because they can be both 0 and 1 at the same time. This means that a quantum computer can perform many calculations at the same time. Giving it the potential to solve certain problems much faster than classical computers.
In addition to superposition, quantum computers rely on another phenomenon called entanglement. Entanglement allows two particles to become connected so that the state of one particle affects the state of the other – even if they are separated by large distances. This enables quantum computers to perform complex calculations and solve problems in a different way to older computer systems.
By harnessing both superposition and entanglement, quantum computers can process and manipulate vast amounts of information at once, allowing them to solve certain types of problems more efficiently and quickly than older binary computers.
But, you won’t be buying one just yet. Building and operating quantum computers is still an ongoing area of research and development.
