Programmable non-Hermitian photonic quantum walks via dichroic metasurfaces
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +6
The evolution of a closed quantum system is described by a unitary operator generated by a Hermitian Hamiltonian. However, when certain degrees of freedom are coupled to an environ…
