Abstract

This paper introduces a mathematical framework for quantum operations that are not constrained to a definite time direction. It explores operations that probe quantum processes in both forward and backward time directions, potentially extending quantum theory. A specific operation, the quantum time flip, is introduced and shown to offer advantages in information-theoretic tasks, highlighting the potential of indefinite time direction in quantum computation.
