Quantum Riddle

What was the main quantum theory that Albert Einstein disagreed with?

• Quantum Mechanics

• String Theory

• General Relativity

• Wave-particle Duality

Answer explanation

Albert Einstein disagreed with the main quantum theory, Quantum Mechanics, due to its probabilistic nature and his belief in determinism.

• Albert Einstein and Neils Bohr

• Isaac Newton and Werner Heisenberg

• Galileo Galilei and Max Planck

• Stephen Hawking and Richard Feynman

Answer explanation

The key figures in the famous debate surrounding quantum mechanics were Albert Einstein and Neils Bohr.

What term did Einstein use to refer to his skepticism of quantum mechanics?

• “Quantum Incoherence”

• “Quantum Paradox”

• “Spooky Action at a Distance”

• “God Does Not Play Dice”

Answer explanation

Einstein referred to his skepticism of quantum mechanics as 'God Does Not Play Dice', highlighting the correct choice.

Which experiment demonstrated the concept of entanglement, a phenomenon that Einstein referred to as "spooky action at a distance"?

• Double-slit experiment

• Bell-test experiments

• Photoelectric effect experiment

• Michelson-Morley experiment

Answer explanation

The Bell-test experiments demonstrated the concept of entanglement, which Einstein referred to as 'spooky action at a distance'. It highlighted the correct choice.

Who proposed the famous "Schrodinger's Cat" thought experiment?

(a)  

Answer explanation

Erwin Schrodinger proposed the famous 'Schrodinger's Cat' thought experiment.

What is the principle that states it's impossible to know both the position and momentum of a particle with perfect accuracy?

• Heisenberg Uncertainty principle

• Pauli Exclusion Principle

• Planck’s Constant

• Schrodinger Equation

Answer explanation

The Heisenberg Uncertainty principle states that it is impossible to know both the position and momentum of a particle with perfect accuracy.

What phenomenon occurs when particles act as waves and exhibit interference patterns when passing through a double-slit?

• Wave-particle duality

• Quantum Entanglement

• Superposition

• Quantum tunneling

What property of a particle changes instantaneously when its entangled partner's property is measured?

• Spin

• Charge

• Velocity

• Position

Answer explanation

When the property of an entangled particle's partner is measured, the spin of the particle changes instantaneously.
