Experimental superposition of time directions
Teodor Strömberg, Peter Schiansky, Marco Túlio Quintino +5
In the macroscopic world, time is intrinsically asymmetric, flowing in a specific direction, from past to future. However, the same is not necessarily true for quantum systems, as…
Nonlinear quantum logic with colliding graphene plasmons
Giuseppe Calajò, Philipp K. Jenke, Lee A. Rozema +3
Graphene has emerged as a promising platform to bring nonlinear quantum optics to the nanoscale, where a large intrinsic optical nonlinearity enables long-lived and actively tunabl…
Giant enhancement of third-harmonic generation in graphene-metal heterostructures
Irati Alonso Calafell, Lee A. Rozema, David Alcaraz Iranzo +13
Nonlinear nanophotonics leverages engineered nanostructures to funnel light into small volumes and intensify nonlinear optical processes with spectral and spatial control. Due to i…
High-harmonic generation enhancement with graphene heterostructures
Irati Alonso Calafell, Lee A. Rozema, Alessandro Trenti +9
We investigate high-harmonic generation in graphene heterostructures consisting of metallic nanoribbons separated from a graphene sheet by either a few-nanometer layer of aluminum…
Semi-device-independent certification of indefinite causal order in a photonic quantum switch
Huan Cao, Jessica Bavaresco, Ning-Ning Wang +7
We report an experimental certification of indefinite causal order that relies only on the characterization of the operations of a single party. We do so in the semi-device-indepen…
