That may seem pretty cold but previous Silicon based Quantum Computers, the type corporate investors like best, needed 0.01 degrees Kelvin. Compared with that 1.25 is blistering hot.</span><o:p></o:p></p><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:13.5pt'><a href="https://www.nature.com/articles/s41586-020-2170-7.epdf?referrer_access_token=XsHdAm9MshAU5-lXuKjHvtRgN0jAjWel9jnR3ZoTv0Mq2y-NgrvDAmaQByJJUjWh0wWMRtvMvesXUkt7Je7E0p153O2QHZlcPk1NQTS0iitw1eOlvcrRnWWLbdRvuKu7Yf-pnUHuLbJiI5MXcKpB-wK9Avrjl6UoIPCSea5LS_ztPSvH62r4BaUh5SDt4IATPX7lb5xsmG73nwD37zFPndXKV6ryW352BW8wlDISsgzVA2kpbkXYbUnEl3L9heDVuWdKULsWTi4kH_xCfSrS7iTC2DlG5TmYwJovdCI6qqhhFE2AVTMXHmVJUiyWw3_gPXq37sYOPKjhWHxIEs8PNBFgA94REcn4eiQzUHmdvcDDrFTTFOnA9uU9KePFJpdOzxU7XzFhWuVcX_pu1unQC1h6wjBe5a3KECp_tHkRwWGlpC667InJhZCA-oGbSF0-gDsU3A2nAmhzggFkbJBwmMfL1y7TiV9mQWsdxjpb5lmjHGiphKS-l_Crhsg25c91&tracking_referrer=www.sciencenews.org">Universal quantum logic in hot silicon qubits</a></span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Arial",sans-serif'>John K Clark<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It’s a coupla orders of magnitude cheaper to maintain something at 1.25K compared to .01K as well.
