Statevector measurement

[rbyrne299]

• Given statevector & number of trials, produce probabilistic counts for each measured state
  • Measured state is one of the basis states, ex. |00>, |01>, |10>, |11> for 2 qubits
  • To find the probability of each basis state, take the square of the norm of the corresponding coefficient
• Apply the appropriate gates before measurement if the user wants to measure in a basis other than the Z basis
  • If X basis, apply Hadamard matrix to statevector before measurement
  • If Y basis, apply Hadamard then S matrix before measurement
