Has quantum advantage been achieved?
Dominik Hangleiter
Quantum computational advantage was claimed for the first time in 2019 and several experiments since then have reinforced and strengthened the claim. At the same time, a new genera…

Peaked quantum advantage using error correction
Abhinav Deshpande, Bill Fefferman, Soumik Ghosh +2
A key issue of current quantum advantage experiments is that their verification requires a full classical simulation of the ideal computation. This limits the regime in which the e…

Code Swendsen-Wang Dynamics
Dominik Hangleiter, Nathan Ju, Umesh Vazirani
Recent advances in quantum Gibbs sampling leave open the central question of rapid mixing near and below phase transitions. This challenge is especially relevant for code Hamiltoni…
