Quantum States

Quantum states are fundamental descriptions of a quantum system, representing all possible information about that system's properties. In quantum information theory, these states can exist in superpositions, meaning a particle can be in multiple states at once, unlike classical bits that are either 0 or 1. A quantum state can be thought of as a complex combination of possibilities, allowing for unique behaviors such as entanglement, where particles become interconnected. This complexity enables powerful processes in quantum computing and secure communications, highlighting the richness of quantum mechanics beyond classical analogies.
