“It is very exciting that our research is receiving international recognition. Understanding how quantum entanglement evolves in time is a key piece for the quantum technologies of the future,” says Axel Stenquist.
The work has been published in the internationally recognised journal Reports on Progress in Physics and has also been highlighted on the Physics World website, where the study is featured through a recommended popular science article.
From atom to photon – an entangled journey
Quantum entanglement is one of the most fascinating phenomena in physics. Two particles can become so strongly linked that a change in one directly affects the other, regardless of distance. In the article “Entanglement transfer in a composite electron-ion-photon system”, Axel Stenquist demonstrates how entanglement can be transferred between different particles in ultrafast processes.
The study describes how an intense light pulse can eject an electron from an atom, creating entanglement between the electron and the remaining ion. When the ion later emits a photon to release energy, the entanglement is transferred further. For a very brief period, all three particles – electron, ion, and photon – are entangled simultaneously.
International attention
The fact that even so-called “regular” research articles can now be published in Reports on Progress in Physics is a relatively new and exciting opportunity for researchers, as the journal is renowned for its high scientific impact. The study’s feature on the Physics World website is a clear recognition of its significance.
The popular science summary has been published in the In Press series on Physics World, following the recommendation of the journal’s editor, highlighting that the study was considered of particular interest to a broader international audience.
In addition to Axel Stenquist, the co-authors of the study are Jakob Bruhnke and Marcus Dahlström from Lund University, and Felipe Zapata from Universidad Complutense de Madrid, Spain.
