What is quantum entanglement, and how does it contribute to the computational advantages of quantum algorithms?
Quantum entanglement is a fundamental phenomenon in quantum mechanics where two or more particles become interconnected in such a way that the state of one particle instantly influences the state of the other, no matter how far apart they are. This phenomenon was first described by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935,
How does the concept of superposition in qubits enable quantum computers to process information differently from classical computers?
The concept of superposition in qubits is a fundamental principle that distinguishes quantum computing from classical computing. In classical computing, information is processed using bits, which can be in one of two states: 0 or 1. Quantum computing, however, utilizes quantum bits or qubits, which can exist in a superposition of states. This means that
