Vanishing performance of the parity-encoded quantum approximate optimization algorithm applied to spin-glass models
Elisabeth Wybo, Martin Leib
The parity mapping provides a geometrically local encoding of the Quantum Approximate Optimization Algorithm (QAOA), at the expense of having a quadratic qubit overhead for all-to-…

Preparing and Analyzing Solitons in the sine-Gordon Model with Quantum Gas Microscopes
Elisabeth Wybo, Alvise Bastianello, Monika Aidelsburger +2
The sine-Gordon model emerges as a low-energy theory in a plethora of quantum many-body systems. Here, we theoretically investigate tunnel-coupled Bose-Hubbard chains with strong r…
