Quantum State Designs from Minimally Random Quantum Circuits
Jonathon Riddell, Katja Klobas, Bruno Bertini
Random many-body states are both a useful tool to model certain physical systems and an important asset for quantum computation. Realising them, however, generally requires an expo…

Rationally independent free fermions with local hopping
Jonathon Riddell, Bruno Bertini
Rationally independent free fermions are those where sums of single-particle energies multiplied by arbitrary rational coefficients vanish only if the coefficients are all zero. Th…
