Qubits

Qubits, short for quantum bits, are the fundamental units of quantum information. 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 in quantum mechanics. This capability allows qubits to perform complex calculations at speeds unattainable by classical computers. In practical terms, a qubit can represent both 0 and 1 at the same time, enabling quantum computers to process a vast amount of data and solve problems through quantum algorithms efficiently. The manipulation of qubits is central to the field of quantum computing, leading to advancements in areas like cryptography, optimization, and simulation of quantum systems.
