Diagonal Unitary Covariant Superchannels
Dariusz Chruściński, Vivek Pandey, Sohail
We present a complete characterization of diagonal unitary covariant (DU-covariant) superchannels, i.e. higher-order transformations transforming quantum channels into themselves.…
Higher-order spectral form factors of circular unitary ensemble
Sohail, Youyi Huang, Lu Wei
Spectral form factor (SFF), one of the key quantity from random matrix theory, serves as an important tool to probe universality in disordered quantum systems and quantum chaos. In…
Unified Framework for Direct and Complete Characterization of an Unknown Kraus Operator and Density Matrix Using a Single Input State
Sahil, Swarup Kumar Giri, Sohail
Characterization of quantum measurements and dynamical processes is typically performed using pure state preparations. However, in realistic experimental settings, the preparation…
Unified Framework for Direct Characterization of Kraus Operators, Observables, Density Matrices, and Weak Values Without Weak Interaction
Sahil, Sohail
Generalized quantum measurements, described by positive operator-valued measures (POVMs), are essential for modeling realistic processes in open quantum systems. While quantum proc…
Bochner's theorem for finite inverse semigroups and its connection to Choi's theorem
Sohail, Sahil
Bochner's theorem characterizes positive definite functions on groups through the positivity of their Fourier transforms and plays a fundamental role in Harmonic analysis. While Bo…
