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…

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…

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…
