Switching quantum reference frames in the N-body problem and the absence of global relational perspectives

Augustin Vanrietvelde, Philipp A. Hoehn, Flaminia Giacomini

Given the importance of quantum reference frames (QRFs) to both quantum and gravitational physics, it is pertinent to develop a systematic method for switching between the descript…

The Dirac equation as a quantum walk over the honeycomb and triangular lattices

Pablo Arrighi, Giuseppe Di Molfetta, Iván Márquez-Martín +1

A discrete-time Quantum Walk (QW) is essentially an operator driving the evolution of a single particle on the lattice, through local unitaries. Some QWs admit a continuum limit, l…
