A Cognitive-Aware QML-CRL Framework for Detecting Affinity and Romance-Investment Fraud

Bibhas Adhikari, Ramya Srinivasan

We present a hybrid quantum-classical framework that detects affinity and romance-investment fraud by modelling the cognitive biases in a manipulative conversation. In our proposed…

Signed network models for portfolio optimization

Bibhas Adhikari

In this work, we consider weighted signed network representations of financial markets derived from raw or denoised correlation matrices, and examine how negative edges can be expl…

Arithmetical Structures on Wheel Graphs

Bibhas Adhikari, Namita Behera, Dilli Ram Chhetri +1

An arithmetical structure on a finite and connected graph G is a pair (d, r) of positive integer vectors such that r is primitive (the gcd of its entries is 1) and (diag(d) - A)r =…

Scalable quantum circuits for exponential of Pauli strings and Hamiltonian simulations

Rohit Sarma Sarkar, Sabyasachi Chakraborty, Bibhas Adhikari

In this paper, we design quantum circuits for the exponential of scaled -qubit Pauli strings using single-qubit rotation gates, Hadamard gate, and CNOT gates. A key result we de…

A quantum neural network framework for scalable quantum circuit approximation of unitary matrices

Rohit Sarma Sarkar, Bibhas Adhikari

In this paper, we develop a Lie group theoretic approach for parametric representation of unitary matrices. This leads to develop a quantum neural network framework for quantum cir…

Local Hamiltonian decomposition and classical simulation of parametrized quantum circuits

Bibhas Adhikari, Aryan Jha

In this paper we develop a classical algorithm of complexity to simulate parametrized quantum circuits (PQCs) of qubits, where is the total number of one-qubi…
