• Quantum

Who proposed the wave-particle duality theory?

• Marie Curie

• Isaac Newton

• Albert Einstein

• Louis de Broglie

What is the Heisenberg Uncertainty Principle?

• It is the principle that determines the speed of light in a vacuum

• It is the law that states all matter is made up of atoms

• It is the theory that explains the behavior of black holes

• It is impossible to simultaneously know both the exact position and momentum of a particle.

What is superposition in quantum mechanics?

• The process of entanglement between quantum particles.

• The ability of a quantum system to travel through time.

• The ability of a quantum system to exist in multiple states simultaneously until measured.

• The collapse of a quantum system into a single state upon measurement.

What is the role of a quantum state in quantum mechanics?

• Quantum state has no impact on the behavior of a quantum system.

• Describes the state of a quantum system and contains information about its properties and behavior.

• Quantum state is only used for entertainment purposes.

• Quantum state is a physical object that can be manipulated directly.

What is entanglement in quantum mechanics?

• Entanglement in quantum mechanics refers to the phenomenon where particles become interconnected in a way that the state of one particle cannot be described independently of the state of the others.

• Entanglement is a term used to describe the randomness of particle behavior in quantum mechanics.

• Entanglement refers to the separation of particles in quantum mechanics.

• Entanglement is a concept that only applies to classical physics, not quantum mechanics.

Explain the concept of quantum tunneling.

• Quantum tunneling is the phenomenon where particles can pass through energy barriers that would be impossible to surmount according to classical physics.

• Quantum tunneling is the process of particles colliding with each other in a quantum system.

• Quantum tunneling is a theory that explains the behavior of light in a vacuum.

• Quantum tunneling is a concept related to the study of black holes.

What is a qubit in quantum computing?

• A qubit is a type of software used for data analysis.

• A qubit is a type of computer chip used in classical computing.

• A qubit is the basic unit of quantum information in quantum computing.

• A qubit is a measurement unit in quantum physics.

What is the significance of Schrödinger's Cat in quantum mechanics?

• Illustrates superposition and quantum indeterminacy

• Highlights the role of quantum decoherence

• Explains the principles of quantum tunneling

• Demonstrates the concept of quantum entanglement

What is the difference between classical and quantum mechanics?

• Classical mechanics only applies to macroscopic objects, while quantum mechanics only applies to microscopic objects.

• Classical mechanics is deterministic, while quantum mechanics is probabilistic.

• Classical mechanics is a subset of quantum mechanics.

• Classical mechanics is based on waves, while quantum mechanics is based on particles.
