Nirjas: An open source framework for extracting metadata from the source code

Ayush Bhardwaj, Sahil, Kaushlendra Pratap +1

Metadata and comments are critical elements of any software development process. In this paper, we explain how metadata and comments in source code can play an essential role in co…

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…
