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…
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…
A prescriptive method for fibre polarisation compensation in two bases
Teodor Strömberg, Peter Schiansky, Philip Walther
Single-mode optical fibres exhibit a small but non-negligible birefringence that induces random polarisation rotations during light propagation. In classical interferometry these r…
Experimental Observation of Earth's Rotation with Quantum Entanglement
Raffaele Silvestri, Haocun Yu, Teodor Stromberg +3
Precision interferometry with quantum states has emerged as an essential tool for experimentally answering fundamental questions in physics. Optical quantum interferometers are of…
Demonstration of a quantum SWITCH in a Sagnac configuration
Teodor Strömberg, Peter Schiansky, Robert W. Peterson +2
The quantum SWITCH is an example of a process with an indefinite causal structure, and has attracted attention for its ability to outperform causally ordered computations within th…
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…
Experimental quantum speed-up in reinforcement learning agents
Valeria Saggio, Beate E. Asenbeck, Arne Hamann +10
Increasing demand for algorithms that can learn quickly and efficiently has led to a surge of development within the field of artificial intelligence (AI). An important paradigm wi…
Genuine Counterfactual Communication with a Nanophotonic Processor
I. Alonso Calafell, T. Strömberg, D. R. M. Arvidsson-Shukur +11
In standard communication information is carried by particles or waves. Counterintuitively, in counterfactual communication particles and information can travel in opposite directi…
