Quantum sensing is an important application of Quantum Information techniques. In this work, we present a mathematical model for a single Qutrit in Λ (Lambda) configuration and its quantum Fisher information.
Quantum sensing is an important application of Quantum Information techniques. In this work, a mathematical model for a single Qutrit in three different representations is presented and their Shannon Mutual Information is compared.
One needs a good communication cost model to understand how best to optimize the off-loaded computation in a tactical environment. In practical scenarios, complications also arise from the in-band and out-of-band channel congestion interference. This can happen due to the intentional and/or unintentional adversary equipment and will affect both the nature of algorithms and the sequence of steps in their execution. As a first step towards solution of the above problems, we present a model for a multi-node tactical network with resource constraints with and without presence of some adversary nodes.
The extraction of useful information from large, disparate, and heterogeneous data sets requires a good set of theoretical and computational tools. The methods based on the ideas of Information Geometry (IG) offer an understanding of the hidden patterns inherent in the data as well as help in their visualization. Fisher Information is such a tool. It has been used widely in many areas of social and economic research leading to an improved understand of trends and hidden patterns. Here we outline its usefulness in understanding large and disparate data sets.
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.
