Bell nonlocality in networks

Armin Tavakoli et al.

Summary: Bell's theorem has proven that quantum theory contradicts local physical models, stimulating research in the foundations of quantum theory and quantum information science. In network scenarios, nonlocal correlations give rise to phenomena that do not exist in traditional Bell experiments, presenting formidable conceptual and practical challenges.

Experimental test of quantum causal influences

Iris Agresti et al.

Summary: Since Bell's theorem, it has been known that local realism fails to explain quantum phenomena. However, recent research has found that in the instrumental scenario, nonclassicality can be observed beyond the classical notions of cause and effect. Through interventions, quantum violations of classical bounds on causal influence can be demonstrated, even without Bell-like violations.

GaAs quantum dots grown by droplet etching epitaxy as quantum light sources

Saimon Filipe Covre da Silva et al.

Summary: This Perspective provides an overview of the epitaxial growth and optical properties of GaAs quantum dots obtained with the droplet etching method as high-quality sources of quantum light. Recent achievements in the generation of single photons and polarization entangled photon pairs are discussed, along with the use of these sources in important quantum communication applications such as entanglement swapping and quantum key distribution.

Quantum teleportation with imperfect quantum dots

F. Basso Basset et al.

Summary: Researchers investigated quantum teleportation protocols using imperfect quantum dots, showing that the average teleportation fidelity could be improved by using a polarization-selective Bell state measurement and moderate spectral filtering, thus easing the stringent requirements on ideal entangled-photon sources. This suggests that imperfect quantum dots can still play a role in quantum communication architectures based on teleportation.

Quantum theory based on real numbers can be experimentally falsified

Marc-Olivier Renou et al.

Summary: Although physical experiments are described using real numbers and probabilities, quantum theory is based on complex numbers and operators. Previous studies showed that real quantum theory can reproduce outcomes of experiments, but new research suggests that real and complex quantum theories make different predictions in network scenarios. This leads to the possibility of devising experiments that could disprove real quantum theory.

Quantum key distribution with entangled photons generated on demand by a quantum dot

Francesco Basso Basset et al.

Summary: Quantum key distribution, a core feature of secure quantum networks, relies on a random secret key exchanged using a quantum mechanical resource. Semiconductor-based quantum emitters show promise in generating high-fidelity entangled photons and countering eavesdropping attacks, potentially moving beyond laboratory experiments to real-life quantum communication.
