Given: Ry(theta) acting on one qubit
I'm trying to use existing Cirq Operators to build the conjugate transpose of the above gate. I need the operator to produce the exact unitary of the given gate for the given theta.
I'v already used cirq.optimizers.single_qubit_matrix_to_gates. It gives YPowGates but the global phase changes with theta. I need either the exact unitary of the gate or another conversion that its global phase does not change with theta.
