Efficient Preparation of Molecular Ground States on Quantum Computers with Givens Rotations
M R Nirmal, Ankit Khandelwal, Manoj Karunakaran Nambiar · 2025
We propose a method to build efficient quantum circuits for molecular electronic structure calculations. The approach uses quantum gates based on Givens rotations, achieving more than 60% reduction in circuit-depth while retaining highly accurate energies.
