Hamiltonians, groups, states and circuits
Abstract: Efficiently calculating the low-lying eigenvalues of Hamiltonians is a fundamental challenge in quantum computing. While various methods have been proposed to reduce the complexity of quantum circuits for this task, there remains room for further improvement. In this talk, I will introduce a framework for constructing shorter and more efficient Hamiltonian-based quantum circuits. Additionally, I will share results from various numerical simulations to demonstrate the effectiveness of our method in accurately determining the ground state energy of different quantum chemistry Hamiltonians.
