*John Preskill *: Explains ���Quantum Supremacy��� https://www.quantamagazine.org/john-preskill-explains-quantum-supremacy-20191002/: 'In the 2012 paper��that introduced the term ���quantum supremacy,��� I wondered: ���Is controlling large-scale quantum systems merely really, really hard, or is it ridiculously hard? In the former case we might succeed in building large-scale quantum computers after a few decades of very hard work. In the latter case we might not succeed for centuries, if ever.��� The recent achievement by the Google team bolsters our confidence that quantum computing is merely really, really hard. If that���s true, a plethora of quantum technologies are likely to blossom in the decades ahead...
