What is quantum physics?

Quantum physics is the branch of physics that studies the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles.

How does it differ from classical physics?

Unlike classical physics, which describes macroscopic phenomena, quantum physics introduces concepts like superposition and entanglement, which don't exist in classical theories.

Can you explain superposition?

Superposition is the principle that a quantum system can exist in multiple states at once until it is measured, at which point it 'collapses' into one of the possible states.

What is entanglement?

Entanglement is a phenomenon where two or more particles become linked, so the state of one instantly influences the state of the other, regardless of distance.

Why is quantum physics important?

Quantum physics is crucial for understanding the fundamental nature of reality and has led to advancements in technology, such as semiconductors and quantum computing.
