Quantum differential operators, encompassing Schrödinger, Dirac and more general elliptic operators, serve as fundamental constructs in the mathematical description of quantum phenomena. Spectral ...

Quantum error-correcting codes are an essential ingredient to protect quantum information in a quantum computer from errors due to coupling to an external environment. Recent progress 1,2,3,4,5 has ...

"For specific examples, however, quantum circuits have already been devised and used to great success in the preparation of exotic topological states of matter on real quantum devices," added Lootens.
