Supervised learning with a quantum classifier using a multi-level system

Soumik Adhikary, Siddharth Dangwal, Debanjan Bhowmik

We propose a quantum classifier, which can classify data under the supervised learning scheme using a quantum feature space. The input feature vectors are encoded in a single qu

A generalised framework for non-classicality of states II: Emergence of non locality and entanglement

Soumik Adhikary, Sooryansh Asthana, V. Ravishankar

A unified formalism was developed in [S. Adhikary et. al., arXiv:1710.04371 [quant-ph]], for describing non-classicality of states by introducing pseudo projection operators in whi…
