Quantum bits (qubits) are the fundamental building blocks of quantum computing. Similar to the classical bit in conventional computers, qubits serve as the smallest storage units and as the unit of measurement for quantum information. Qubits are governed by the principles of quantum mechanics. Unlike classical bits, they can exist in a state of superposition, meaning they can simultaneously represent multiple quantum states. This allows for the simultaneous execution of multiple computations, particularly beneficial in optimization and simulating complex systems.

Additionally, qubits can be entangled, which means the state of one qubit can directly influence the state of another. This property is particularly relevant in quantum encryption.

Quantum bits offer the potential for powerful computations and innovative applications in various fields of computer science and science.
