Researchers have devised a new way to make digital information exchange safer, cheaper, and more environmentally friendly.
quantum random number generation protocols instead of lasers that are typically used to generate the random numbers in the encryption process.The properties of perovskite used, which is based on an indium tin oxide -coated glass substrate, make it a cheaper and morefriendly alternative in QRNGs. The material's optical and mechanical qualities are important drivers for utilization, and also has a smaller carbon footprint over its full life cycle.
“It’s possible to use, for example, a traditional laser for QRNG, but it’s expensive. If the technology is eventually to find its way into consumer electronics, it’s important that the cost is kept down and that the production is as environmentally friendly as possible. In addition, PeLEDs don’t require as much energy to run,” said Feng Gao, a professor at the University's Department of Physics, Chemistry, and Biology, in a statement.
The researchers claim that their model has passed the stringent NIST randomness test suite and has "guaranteed the privacy of at least 71% of the generated random numbers by implementing our QRNG with the MDI approach," said the study. The next phase is to refine the substance further to eliminate lead from the perovskite and increase its lifespan, which is now 22 days. The team hopes that within five years, their new QRNG might be used in cybersecurity.The recent development of perovskite light-emitting diodes has the potential to revolutionize the fields of optical communication and lighting devices, due to their simplicity of fabrication and outstanding optical properties.

Researchers define protocol for high-resolution imaging of living cells using atomic force microscopyImages of nanoscale structures inside living cells are in increasing demand for the insights into cellular structure and function that they can reveal. So far, the tools for capturing such images have been limited, but researchers led by Takeshi Fukuma and Takehiko Ichikawa at Kanazawa University have now devised and reported a full protocol for using atomic force microscopy (AFM) to image inside living cells. The research is published in the journal STAR Protocols.
