Tomographic measurement data of states that never existed
Julian Göttsch, Stephan Grebien, Felix Pein +6
Microscopic Schr{ö}dinger cat states are generated from quantum correlated fields using a probabilistic heralding photon subtraction event. Subsequent quantum state tomography prov…

Free temporal evolution of a superbandwidth wave packet: The quantum tale of the hare and the tortoise
Enrique G. Neyra, Marcelo F. Ciappina, Lorena Rebón
Can the interplay between quantum mechanics and classical optics offer new perspectives on wavepacket dynamics? Building on this connection, we show that local momenta with both su…

Experimental characterization of quantum processes: a selective and efficient method in arbitrary finite dimension
Quimey Pears Stefano, Ignacio Perito, Juan José Miguel Varga +2
The temporal evolution of a quantum system can be characterized by quantum process tomography, a complex task that consumes a number of physical resources scaling exponentially wit…
