Hamiltonian-based graph-state ansatz for variational quantum algorithms
Abhinav Anand, Kenneth R. Brown
One promising application of near-term quantum devices is to prepare trial wavefunctions using short circuits for solving different problems via variational algorithms. For this pu…
Leveraging commuting groups for an efficient variational Hamiltonian ansatz
Abhinav Anand, Kenneth R. Brown
Efficiently calculating the low-lying eigenvalues of Hamiltonians, written as sums of Pauli operators, is a fundamental challenge in quantum computing. While various methods have b…
Hybrid ACO-CI Algorithm for Beam Design problems
Ishaan R Kale, Mandar S Sapre, Ayush Khedkar +3
A range of complicated real-world problems have inspired the development of several optimization methods. Here, a novel hybrid version of the Ant colony optimization (ACO) method i…
Partitioning Quantum Chemistry Simulations with Clifford Circuits
Philipp Schleich, Joseph Boen, Lukasz Cincio +5
Current quantum computing hardware is restricted by the availability of only few, noisy qubits which limits the investigation of larger, more complex molecules in quantum chemistry…
Exploring the role of parameters in variational quantum algorithms
Abhinav Anand, Sumner Alperin-Lea, Alexandre Choquette +1
In this work, we introduce a quantum-control-inspired method for the characterization of variational quantum circuits using the rank of the dynamical Lie algebra associated with th…
Quantum compression with classically simulatable circuits
Abhinav Anand, Jakob S. Kottmann, Alán Aspuru-Guzik
As we continue to find applications where the currently available noisy devices exhibit an advantage over their classical counterparts, the efficient use of quantum resources is hi…
Information flow in parameterized quantum circuits
Abhinav Anand, Lasse Bjørn Kristensen, Felix Frohnert +2
In this work, we introduce a new way to quantify information flow in quantum systems, especially for parameterized quantum circuits. We use a graph representation of the circuits a…
