=== Storz et al (2023): Loophole-free Bell inequality violation with superconducting circuits ===
In 2023, an international team led by the group of [[Andreas Wallraff]] at [[ETH Zurich]] demonstrated a loophole-free violation of the [[CHSH inequality]] with superconducting circuits deterministically entangled via a cryogenic link spanning a distance of 30 meters.<ref>{{cite journal |last1=Storz |first1=Simon |last2=Schär |first2=Joshua |last3=Kulikov |first3=Anatoly |last4=Magnard |first4=Paul |last5=Kurpiers |first5=Philipp |last6=Lütolf |first6=Janice |last7=Walter |first7=Theo |last8=Copetudo |first8=Adrian |last9=Reuer |first9=Kevin |last10=Akin |first10=Abdulkadir |last11=Besse |first11=Jean-Claude |last12=Gabureac |first12=Mihai |last13=Norris |first13=Graham J. |last14=Rosario |first14=Andrés |last15=Martin |first15=Ferran |last16=Martinez |first16=José |last17=Amaya |first17=Waldimar |last18=Mitchell |first18=Morgan W. |last19=Abellan |first19=Carlos |last20=Bancal |first20=Jean-Daniel |last21=Sangouard |first21=Nicolas |last22=Royer |first22=Baptiste |last23=Blais |first23=Alexandre |last24=Wallraff |first24=Andreas |date=2023 |title=Loophole-free Bell inequality violation with superconducting circuits  |journal=Nature |volume=617 |issue= 7960|pages=265–270 |doi=10.1038/s41586-023-05885-0 |pmid=37165240 |bibcode=2023Natur.617..265S |doi-access=free |hdl=20.500.11850/612915 |hdl-access=free }}</ref>
