Qubits
Qubits, or quantum bits, are the fundamental units of information in quantum computing. Unlike classical bits, which can exist in one of two states (0 or 1), qubits can exist simultaneously in multiple states due to the principles of superposition and entanglement. This allows qubits to represent and process a vast amount of information in parallel, making quantum computers potentially much more powerful than traditional computers for certain tasks. The behaviour of qubits is governed by the principles of quantum mechanics, which enables them to perform complex calculations and solve problems that are currently intractable for classical computers.
