Indefinite Time Directed Quantum Metrology

We explore the performance of the metrology scheme by employing a quantum time flip during encoding, a specific case of processes with indefinite time direction, which we refer to as indefinite time directed metrology ($ITDM$). In the case of single parameter estimation of a unitary, we demonstrate...
