Quantum-centric Supercomputing for Materials Science: A Perspective on Challenges and Future Directions
Yuri Alexeev, Maximilian Amsler, Paul Baity +124
Computational models are an essential tool for the design, characterization, and discovery of novel materials. Hard computational tasks in materials science stretch the limits of e…
Probing Quantum Efficiency: Exploring System Hardness in Electronic Ground State Energy Estimation
Seonghoon Choi, Ignacio Loaiza, Robert A. Lang +2
We consider the question of how correlated the system hardness is between classical algorithms of electronic structure theory in ground state estimation and quantum algorithms. To…
Coherent control based on quantum Zeno and anti-Zeno effects: Role of coherences and timing
Jacob Levitt, Artur F. Izmaylov
The quantum-Zeno and anti-Zeno effects (QZE/AZE) are known for a long time, in a quantum system with coupled levels, the measurement of a particular level population can lead to ei…
Extension of exactly-solvable Hamiltonians using symmetries of Lie algebras
Smik Patel, Tzu-Ching Yen, Artur F. Izmaylov
Exactly-solvable Hamiltonians that can be diagonalized using relatively simple unitary transformations are of great use in quantum computing. They can be employed for decomposition…
A hybrid quantum-classical algorithm for multichannel quantum scattering of atoms and molecules
Xiaodong Xing, Alejandro Gomez Cadavid, Artur F. Izmaylov +1
We propose a hybrid quantum-classical algorithm for solving the time-independent Schrödinger equation for atomic and molecular collisions. The algorithm is based on the -matrix…
Block-Invariant Symmetry Shift: Preprocessing technique for second-quantized Hamiltonians to improve their decompositions to Linear Combination of Unitaries
Ignacio Loaiza, Artur F. Izmaylov
Computational cost of energy estimation for molecular electronic Hamiltonians via Quantum Phase Estimation (QPE) grows with the difference between the largest and smallest eigenval…
