Shannon mutual information of a qutrit in cascade model
Vinod Kumar Mishra · 2019
Quantum sensing is an important application of Quantum Information (QI) techniques and usually entangled Qubits are used for this task. The sensor sensitivity depends on QI metrics like Shannon Mutual Information (SMI). In this work we present a mathematical model for calculating 1-Qutrit SMI and compare that with 1-Qubit SMI. Qutrit in cascade configuration is found to have higher SMI and so it a better Quantum Sensor for constant fields.
