Qubits, or quantum bits, are the fundamental units of quantum information used in quantum computing, representing a state of quantum systems. Unlike classical bits that can only be in a state of 0 or 1, qubits can exist in multiple states simultaneously due to the principles of superposition and entanglement, making them crucial for advanced computational tasks. This unique behavior allows qubits to perform complex calculations at unprecedented speeds, paving the way for breakthroughs in various fields such as cryptography and communication.
