Quantum Mechanics and Technology Quiz

What was the major shift in understanding introduced by Schrodinger and Heisenberg?

• The universe is deterministic and predictable.

• Atoms behave in predictable ways.

• The universe is fuzzy and uncertain at a microscopic level.

• Particles cannot exist in multiple places at once.

What does the concept of superposition allow particles to do?

• Exist in one place at a time.

• Move in one direction only.

• Be in two locations or states simultaneously.

• Remain stationary.

In Schrodinger's thought experiment, what is the state of the cat before the box is opened?

• Both alive and dead.

• Alive only.

• Dead only.

• Neither alive nor dead.

What is quantum entanglement?

• Particles that cannot be observed.

• Particles moving in the same direction.

• Particles linked in a way that defies classical physics.

• Particles existing independently.

How did Einstein describe quantum entanglement?

• A predictable phenomenon.

• A logical explanation.

• Spooky action at a distance.

• A simple concept.

What is a key feature of quantum computers compared to classical ones?

• They use classical bits.

• They use qubits that can be in multiple states.

• They are less efficient.

What potential does quantum computing have?

• To slow down technological progress.

• To make current encryption methods obsolete.

• To revolutionize industries and tackle climate change.

• To replace all classical computers.

What is quantum sensing used for?

• Predicting weather patterns.
