Attention-based optimizer for symmetry finding
Shreya Banerjee, Vinodh Raj Rajagopal Muthu, Charlie Nation +5
Finding symmetries is crucial for understanding physical models. In this work, we present an optimization framework that searches Pauli symmetries of Hamiltonians, merging the fiel…
Graph automorphisms to obtain Clifford symmetries in open and closed qudit models
Charlie Nation, Rick P. A. Simon, Shreya Banerjee +4
In the recent article [arXiv:2605.18966], we demonstrated that finding Clifford symmetries can be mapped to a Graph Automorphism (GA) problem. Here, we provide an algorithm to obta…
Clifford symmetries in quantum many-body systems
Charlie Nation, Rick P. A. Simon, Shreya Banerjee +4
Obtaining the symmetries of a model is a critical step towards developing an understanding and ultimately analytically or numerically solving the model. However, finding symmetries…
Hierarchical QAOA for the Vehicle Routing Problem via Clustered Decomposition and Local Feasibility Repair
Shreetam Dash, Shreya Banerjee, Prasanta K. Panigrahi
We propose a hierarchical quantum approximate optimization framework for solving large-scale Vehicle Routing Problems (VRP) using Quantum Approximate Optimization Algorithm (QAOA).…
Counting with the quantum alternating operator ansatz
Julien Drapeau, Shreya Banerjee, Stefanos Kourtis
We introduce a variational algorithm based on the quantum alternating operator ansatz (QAOA) for the approximate solution of computationally hard counting problems. Our algorithm,…
Quantum Dialogue through Non-destructive Discrimination of Cluster State
Mandar Thatte, Shreya Banerjee, Prasanta K. Panigrahi
We propose an efficient, measurement-based quantum dialogue protocol through non-destructive discrimination (NDD) of cluster state. We use ancilla-based measurements that allow the…
