The von Neumann architecture for a classical computer comprises a central processing unit and a memory holding instructions and data. We demonstrate a quantum central processing unit that exchanges data with a quantum random-access memory integrated on a chip, with instructions stored on a classical computer.
MicroRNAs are a class of short (~18–22 nucleotides) non-coding RNAs that are important in development and cell differentiation, the regulation of the cell cycle, apoptosis and signalling pathways 1 , 2 . Since its initial discovery in Caenorhabditis elegans in 1993 (ref. 3 ), over 17,000 microRNAs have been identified across different species, including humans 4 . In the cytoplasm, mature microRNAs are associated with an RNA-induced silencing protein complex to bind with the 3′-untranslated region of target messenger RNAs 1 , 5 , 6 .
