We provide the first two-party protocol allowing Alice and Bob to evaluate privately even against active adversaries any completely positive, trace-preserving map given as a quantum circuit upon their joint quantum input state. Our protocol leaks no more to any active adversary than an ideal functionality for the map, provided Alice and Bob have the cryptographic resources for active secure two-party classical computation.
