  • Spacetime fluctuations have been predicted by a plethora of semiclassical and quantum models of gravity. Here, the authors discuss how characteristic signatures of classes of such spacetime fluctuations can be identified in laser interferometers.

  • While most quantum optical techniques reveal either the wave or particle nature of light, weak-field homodyne detection combines wave- and particle-like descriptions. Here, Donati et al.employ this hybrid detection scheme to study the coherence between photon number states across two-mode entangled states.

  • The use of a new measure of what it means for a system to be quantum has profound technological and philosophical ramifications for the field of quantum information processing.

  • Bhattacharjee and Schaeffer et al. map exclusive breastfeeding (EBF) in 94 low- and middle-income countries (LMICs), finding increased EBF practice and reduced subnational variation across the majority of LMICs from 2000 to 2018. However, only six LMICs will meet WHO’s target of ≥70% EBF by 2030 nationally, and only three will achieve this in all districts.

  • By developing full quantum detector tomography, researchers simultaneously characterize the wave- and photon-number sensitivities of quantum-optical detectors to yield the largest ever parametrization in a quantum tomography experiment. The presented results reveal the role of coherence in quantum measurements and demonstrate the tunability of hybrid quantum-optical detectors.

  • Phase estimation is an important element of quantum metrology, but the influence of noise cannot always be well characterized. Vidrighin et al.analyse and experimentally demonstrate methods providing simultaneous estimation of a phase shift and the amplitude of phase diffusion at the quantum limit.

  • The rich ethnolinguistic and sociocultural differences that exist in India offers a unique opportunity to study human diversity. With the whole genomes of 10,000 healthy and unrelated Indians from 83 populations, the GenomeIndia project captures the genetic diversity of one of the highly underrepresented populations in the global genomics landscape.
