What is quantum entanglement?

• A process where particles lose all energy

• A phenomenon where two or more particles become linked and share states

• A method of measuring temperature

• A type of classical encryption

What is the main purpose of quantum teleportation?

• To move physical objects instantly

• To transfer quantum information from one place to another

• To increase the speed of light

• To create new particles

Which property allows quantum sensors to detect very small changes in their environment?

• Magnetism

• Coherence

• Gravity

• Friction

What is superposition in quantum mechanics?

• The ability of a particle to be in only one state at a time

• The ability of a particle to be in multiple states at once

• The process of measuring a particle

• The loss of information

Which of the following is a key feature of quantum cryptography?

• It uses classical keys

• It relies on quantum uncertainty

• It is based on prime numbers

• It uses only mechanical devices

What is the main difference between quantum and classical computing?

• Quantum computing uses bits, classical uses qubits

• Classical computing uses qubits, quantum uses bits

• Quantum computing uses qubits, which can be in superposition

• Both use the same type of information

Which term describes the loss of quantum information due to interaction with the environment?

• Superposition

• Decoherence

• Entanglement

• Teleportation

What is a qubit?

• A classical bit

• A quantum bit that can be in a superposition of 0 and 1

• A type of encryption

• A measurement device

Which of the following is NOT an application of quantum computing?

• Factoring large numbers

• Weather prediction

• Cooking food

• Simulating molecules

What does quantum uncertainty mean?

• The position and momentum of a particle can be known exactly at the same time

• There is a limit to how precisely we can know certain pairs of properties

• All particles behave predictably

• Quantum systems never change
