A basis-independent closed-form exponential unitary maps any two pure states without scaling with Hilbert space dimension.
Precomputes rotation angles classically and adds a magnitude-then-phase procedure to enable complex-valued state preparation on BBQRAM at unchanged O(log²(MN)) query cost with no reversible arithmetic on the QPU.
