Geometric Parameterization of Kraus Operators with Applications to Quasi Inverse Channels for Multi Qubit Systems
Zain Ateeq, Muhammad Faryad
This work presents a differentiable geometric parameterization of quantum channels in Kraus representation, which can be efficiently probed to find an unknown quantum channel. We e…
Noise Thresholds for Quantum Advantage in the Bernstein-Vazirani and Deutsch-Jozsa Algorithms
Muhammad Faizan, Muhammad Faryad
We analytically investigate the robustness of the Bernstein-Vazirani and Deutsch-Jozsa algorithms against single-qubit Pauli noise, of which bit-flip, phase-flip, and depolarizing…
Enhancement of non-Markovianity due to environment-induced indirect interaction
Asif Zaman, Muhammad Faryad, Adam Zaman Chaudhry
Non-Markovian effects are often significant when the system-environment coupling is not weak. Indeed, we find that the non-Markovianity is negligible for a single two-level system…
Physics-inspired neural networks as quasi inverse of quantum channels
Sameen Aziz, Muhammad Faryad
Quantum channels are not invertible in general. A quasi-inverse allows for a partial recovery of the input state, but its analytical results are found only in a restricted space of…
