Homework Help: Quantum Physics

Posted by qwerty on Sunday, March 3, 2013 at 6:11pm.

Suppose Alice starts with two qubits in the Bell state 1/√2 (|00> + |11>) and teleports these qubits to Bob by applying the quantum teleportation protocol to each qubit separately.

(a) What is the state of the two qubits received by Bob?

|00> =
|01> =
|10> =
|11> =

(b) How many classical bits did Alice send to Bob?

  a)00> = 1/sqrt2
  |01> = 0
  |10> = 0
  |11> =0
  
  b) 4
