  • Understanding the confinement and transport of excitons in low dimensional systems will aid the development of next generation photovoltaics. Via photophysical studies Ni et al. observe 'quantum cutting' in 0D metal-organic hybrid materials based on methylammonium bismuth halide (CH3NH3)3Bi2I9.

  • Quantum digital signatures exploit quantum mechanics to provide verification of messages at the limits of information theory. Clarkeet al.demonstrate a photonic system that provides quantum digital signatures for messages sent to two receivers and is secure against forgery and repudiation.

  • The radiation produced when an intense laser interacts with a solid target could provide a cheaper source of X-rays to synchrotrons and free-electron lasers. But they can also produce short bursts of gamma rays, whereas synchrotrons do not.

  • In scaling to global distances, future quantum networks are expected to make use of satellite-based orbiting quantum memories. In this manuscript, the authors simulate the performance of memory-assisted quantum key distribution (MA-QKD) schemes under a range of operating conditions and network configurations, with encouraging conclusions as to the feasibility of implementing such networks with near-term devices.

  • Centromeric chromatin differs from bulk chromatin in many aspects, including a distinct organization and the presence of different histone variants. Studies have focused on elucidating the molecular and physical architecture of centromeric chromatin, as well as the properties that make it invaluable during chromosome segregation in mitosis.

  • The challenge of transmitting noise-free quantum optical signals needs to be overcome before they can be readily applied to quantum communication devices. The authors present a method using standard components to amplify quantum optical signals while reducing the effects of noise and maintain a high-quality, secure signal.

  • Ellegaard et al. discuss the potential for using ancient environmental DNA (eDNA), combined with resurrection ecology, to analyse trophic interactions and evolutionary adaptation to changing environments. Their Review suggests that these techniques will improve our ability to predict genetic and phenotypic adaptation to environmental stress.
