Working through Lab 3 in the Qiskit text, I have been attempting to initialize my one qubit circuit with two random numbers. My first attempt, as directed, is using
.initialize function, but I keep getting an error:'Sum of amplitudes-squared does not equal one.'
qc = QuantumCircuit(1) #### your code goes here #Create random initial state SignChoice=[1,-1] a=random.choice(SignChoice)*random.random() b=random.choice(SignChoice)*random.random() p=complex(a,b) q=np.sqrt(1-p**2) initial_state = [p,q] # Define state |q_0> qc.initialize(initial_state, 0) # Initialise the 0th qubit in the state `initial_state`
In attempting to fix this error I have used the code below to see my amplitudes and the sum of their squares and though I can see that rounding may sometimes be an issue, it does often result in exactly 1+0j, which leaves me wondering why it will not initialize!
My second attempt will be with
but I have not yet completed it.
