Quantum computing is a revolutionary technology that is changing the way we approach complex problems and process information. By harnessing the power of quantum mechanics, quantum computers can perform calculations exponentially faster than classical computers, opening up new possibilities for fields such as medicine, finance, and climate modelling.
What is Quantum Computing?
Quantum computing is a type of computing that uses the principles of quantum mechanics to perform calculations. Unlike classical computers, which use bits to represent information as either 0 or 1, quantum computers use quantum bits or qubits. Qubits can exist in multiple states simultaneously, allowing for parallel processing of vast amounts of data.
How Does Quantum Computing Work?
Quantum computing works by exploiting the principles of superposition, entanglement, and interference. Qubits are created and manipulated using quantum gates, which are the quantum equivalent of logic gates in classical computing. The qubits are then measured, collapsing their superposition into a single state, which represents the solution to the problem being solved.
