Multiple choice

What is quantum entanglement?

  1. A phenomenon where two particles become correlated in such a way that the state of one particle cannot be described independently of the other.

  2. A phenomenon where two particles become entangled in such a way that they share the same fate.

  3. A phenomenon where two particles become correlated in such a way that they can communicate with each other instantaneously.

  4. A phenomenon where two particles become entangled in such a way that they can be used to send information faster than the speed of light.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Quantum entanglement is a phenomenon where two particles become correlated in such a way that the state of one particle cannot be described independently of the other. This means that if you measure the state of one particle, you instantly know the state of the other particle, even if they are separated by a large distance.

Multiple choice

What is the EPR paradox?

  1. A paradox that arises from the phenomenon of quantum entanglement.

  2. A paradox that arises from the phenomenon of wave-particle duality.

  3. A paradox that arises from the phenomenon of superposition.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The EPR paradox is a paradox that arises from the phenomenon of quantum entanglement. It was first proposed by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935. The paradox is that if two particles are entangled, then measuring the state of one particle instantly reveals the state of the other particle, even if they are separated by a large distance. This seems to violate the principle of locality, which states that no information can travel faster than the speed of light.
