Random bit sequences are key ingredients of various tasks in modern life and especially in secure communication. In a new study researchers have determined that generating true random bit sequences, classical or quantum, is an impossible mission. [27] A quantum circuit that can unambiguously test for information scrambling in an experiment could help verify the calculations of quantum computers and even shed more light on what happens to quantum information when it falls into a black hole. [26] Researchers at the University of Florence and Istituto dei Sistemi Complessi, in Italy, have recently proved that the invasiveness of quantum measurements might not always be detrimental. [25] Now, researchers in the UK and Israel have created miniscule engines within a block of synthetic diamond, and have shown that electronic superposition can boost their power beyond that of classical devices. [24] In the latest wrinkle to be discovered in cubic boron arsenide, the unusual material contradicts the traditional rules that govern heat conduction, according to a new report by Boston College researchers in today's edition of the journal Nature Communications. [23] Beyond the beauty of this phenomenon, which connects heating processes to topology through an elegant quantization law, the results reported in this work designate heating measurements as a powerful and universal probe for exotic states of matter.
