Experimental Aspects of Indefinite Causal Order in Quantum Mechanics
Lee A. Rozema, Teodor Strömberg, Huan Cao +3
In the past decade, the toolkit of quantum information has been expanded to include processes in which the basic operations do not have definite causal relations. Originally consid…

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…

Direct and Efficient Detection of Quantum Superposition
Daniel Kun, Teodor Strömberg, Michele Spagnolo +3
One of the most striking quantum phenomena is superposition, where one particle simultaneously inhabits different states. Most methods to verify coherent superposition are indirect…
