Improved bounds for connection probabilities in random loop models
Volker Betz, Andreas Klippel, Julian Nauth
We revisit and extend results by Ueltschi [19] on the application of reflection positivity to loop models with . By exploiting additional flexibility in t…

Dicke-state preparation through global transverse control of Ising-coupled qubits
Vladimir M. Stojanovic, Julian K. Nauth
We consider the problem of engineering the two-excitation Dicke state in a three-qubit system with all-to-all Ising-type qubit-qubit interaction, which is also…
