Sublinear-depth Quantum Simulation of Electrons with Atomic Orbitals
Jakob Günther, Aram W. Harrow
Discretizing electronic degrees of freedom into atomic orbitals is the default choice to accurately model electrons in molecules in a compact and flexible way. We consider the task…
phase2: Full-State Vector Simulation of Quantum Time Evolution at Scale
Marek Miller, Jakob Günther, Freek Witteveen +5
Classical simulation of quantum computers is essential for designing and benchmarking quantum algorithms. Here we present phase2, a full-state-vector simulator optimised for sequen…
High ground state overlap via quantum embedding methods
Mihael Erakovic, Freek Witteveen, Dylan Harley +7
Quantum computers can accurately compute ground state energies using phase estimation, but this requires a guiding state that has significant overlap with the true ground state. Fo…
More quantum chemistry with fewer qubits
Jakob Günther, Alberto Baiardi, Markus Reiher +1
Quantum computation is one of the most promising new paradigms for the simulation of physical systems composed of electrons and atomic nuclei, with applications in chemistry, solid…
A state-averaged orbital-optimized hybrid quantum-classical algorithm for a democratic description of ground and excited states
Saad Yalouz, Bruno Senjean, Jakob Günther +3
In the Noisy Intermediate-Scale Quantum (NISQ) era, solving the electronic structure problem from chemistry is considered as the "killer application" for near-term quantum devices.…
