De kwantumwereld gaat het komende decennium baanbrekende veranderingen teweeg brengen in politiek, economie, sociologie.
Deze hele website gaat daarover. Elke keer weer refereer ik naar bestaande literatuur: om te laten zien hoe breed gedragen deze ontwikkeling in de wereld is. Hieronder een artikel uit de Economist – TECHNOLOGY QUARTERLY – HERE, THERE AND EVERYWHERE – Quantum technology is beginning to come into its own. After decades as laboratory curiosities, some of quantum physics’ oddest effects are beginning to be put to use, says Jason.
Een paar quotes hieruit:
Field trials have shown that delicate quantum light signals can be sent through the same fibres that bring the internet to homes and businesses. And efforts to make quantum-enhanced versions of the equipment that amplifies and distributes standard optical signals are bearing fruit. Quantum networks are springing up or expanding. And quantum communications, just like their conventional counterparts, will soon be whizzing through space, too.
No quantum network is more ambitious than the one completed in China at the end of last year. Funded by the central government, it links Beijing and Shanghai via Jinan, which already has a metro network over 70 square kilometres, made up of 50 “nodes”—switchboards connecting senders and receivers—and Hefei, which has a 46-node network. Its customers include China Industrial and Commercial Bank, the China Banking Regulatory Commission and the Xinhua news agency.
Google is aiming to use its own machinery, a so-called gate-model quantum computer of the sort most groups are pursuing, to achieve “quantum supremacy”, whereby a quantum computer performs a calculation faster than any known computer could. Google researchers have laid out an ambitious plan which may let them achieve that feat this year. D-Wave has hinted it has already done so, but has made similar claims in the past; their current numbers are still to be checked.
One of the most ambitious, LIQUi|> (whose name plays on a symbol in quantum mechanics), comes from Microsoft. It aims to tackle the whole “software stack”, from the user interface to code-compilers and ultimately to a machine language suitable for Microsoft’s planned hardware, and that of others.
Of kijk in het artikel in AEON met dezelfde boodschap.
