Improved Strategies for Fermionic Quantum Simulation with Global Interactions

Thierry N. Kaldenbach, Erik Schultheis, Niklas Stewen +1

We present efficient quantum circuits for fermionic excitation operators tailored for ion trap quantum computers exhibiting the Mølmer-Sørensen (MS) gate. Such operators commonly…
