Quantum Gate

A quantum gate is a fundamental operation that manipulates qubits—the basic units of quantum information—much like classical logic gates do for traditional bits. Unlike traditional gates, which perform simple yes/no operations, quantum gates leverage quantum properties like superposition and entanglement to change a qubit’s state in complex ways. This manipulation allows quantum computers to explore many possibilities simultaneously, enabling powerful computation for specific problems. In essence, quantum gates control the behavior of qubits, directing how they evolve and interact, forming the building blocks of quantum algorithms.
