What is quantum computing and how does it work?

Quantum computing is a type of computation that uses quantum bits, or qubits, which can exist in multiple states simultaneously. This allows quantum computers to process information in ways that classical computers cannot.

What are qubits and how do they differ from classical bits?

Qubits are the fundamental units of quantum information. Unlike classical bits, which can be either 0 or 1, qubits can be in a state of 0, 1, or both at the same time due to a property called superposition.

Can you explain superposition and entanglement?

Superposition allows qubits to be in multiple states at once, while entanglement is a phenomenon where qubits become interconnected, such that the state of one qubit can depend on the state of another, no matter the distance between them.

What are some practical applications of quantum computing?

Quantum computing has potential applications in cryptography, drug discovery, optimization problems, and complex simulations in physics and chemistry.
