Duality between quantum channels and super-channels is basis-dependent
Sohail, Sahil, Ritabrata Sengupta +1
The complete positivity vs positivity correspondence in the Choi-Jamiołkowski-Kraus-Sudarshan quantum channel-state isomorphism depends on the choice of basis. Instead of the "cano…
Exact Quantum Speed Limits
Arun K. Pati, Brij Mohan, Sahil +1
The traditional quantum speed limits are not attainable for many physical processes, as they tend to be loose and fail to determine the exact time taken by quantum systems to evolv…
Uncertainty Relations in Pre- and Post-Selected Systems
Sahil, Sohail, Sibasish Ghosh
In this work, we derive Robertson-Heisenberg like uncertainty relation for two incompatible observables in a pre- and post-selected (PPS) system. The newly defined standard deviati…
Extraction of Product and Higher Moment Weak Values: Applications in Quantum State Reconstruction and Entanglement Detection
Sahil, Sohail, Subhrajit Modak +2
Weak measurements introduced by Aharonov, Albert and Vaidman (AAV) can provide informations about the system with minimal back action. Weak values of product observables (commuting…
