Suppose you are given an endless supply of qubits in the state 12√|00⟩+eiϕ2√|10⟩. To estimate the phase angle ϕ, you run Fourier sampling (i.e. Hadamard on each qubit followed by a standard basis measurement) on this state repeatedly. After 100,000,000 measurements, you find that the outcome 01 never occurred. What is ϕ? Please provide your answer in the range ϕ∈[0,2π).
