Question 3

What is entanglement in quantum computing?

Accepted Answer

Two or more particles can be connected in a way that the state of one particle can influence the state of the other particle, regardless of the distance between them

Answer

Two or more particles cannot be in the same state

Answer

Two or more particles can exchange energy with each other

Answer

Two or more particles can exist in the same location

A method to destroy quantum information

Answer

A method to measure quantum particles

Answer

A method to physically move quantum particles from one location to another

Question 5

What is the difference between a classical bit and a qubit?

Accepted Answer

A classical bit can only exist in two states (0 or 1), while a qubit can exist in a superposition of both states

Answer

A classical bit can exist in a superposition of both states, while a qubit can only exist in two states (0 or 1)

Answer

A qubit can only exist in the state 0, while a classical bit can exist in any state

Answer

A qubit can exist in multiple states at once, while a classical bit can only exist in one state at a time
