Coherent consensus for the estimation and classification of phases
Roberto Ruiz, Alessandro Luongo, Sergi Ramos-Calderer +1
Inspired by quantum metrology, we propose a coherent consensus primitive to enhance the collaborative performance of independent quantum classifiers at the decision boundary. The b…
Efficient Eigenstate Preparation in an Integrable Model with Hilbert Space Fragmentation
Roberto Ruiz, Alejandro Sopena, Balázs Pozsgay +1
We consider the preparation of all the eigenstates of spin chains using quantum circuits. It is known that generic eigenstates of free-fermionic spin chains can be prepared with ci…
Bethe Ansatz, Quantum Circuits, and the F-basis
Roberto Ruiz, Alejandro Sopena, Esperanza López +2
The Bethe Ansatz is a method for constructing exact eigenstates of quantum-integrable spin chains. Recently, deterministic quantum algorithms, referred to as "algebraic Bethe circu…
