Dynamic conditioning of two particle discrete-time quantum walks
Federico Pegoraro, Philip Held, Sonja Barkhofen +2
In real photonic quantum systems losses are an unavoidable factor limiting the scalability to many modes and particles, restraining their application in fields as quantum informati…

Experimental Observation of Topological Quantum Criticality
Sonja Barkhofen, Syamsundar De, Jan Sperling +5
We report on the observation of quantum criticality forming at the transition point between topological Anderson insulator phases in a one-dimensional photonic quantum walk with sp…
