Editing Quantum entanglement (section)

=== Entanglement of macroscopic objects ===
In 2020, researchers reported the quantum entanglement between the [[Vibrations of a circular membrane|motion of a millimetre-sized mechanical oscillator]] and a disparate distant spin system of a cloud of atoms.<ref>{{cite journal |last1=Thomas |first1=Rodrigo A. |last2=Parniak |first2=Michał |last3=Østfeldt |first3=Christoffer |last4=Møller |first4=Christoffer B. |last5=Bærentsen |first5=Christian |last6=Tsaturyan |first6=Yeghishe |last7=Schliesser |first7=Albert |last8=Appel |first8=Jürgen |last9=Zeuthen |first9=Emil |last10=Polzik |first10=Eugene S. |title=Entanglement between distant macroscopic mechanical and spin systems |journal=Nature Physics |date=21 September 2020 |volume=17 |issue=2 |pages=228–233 |doi=10.1038/s41567-020-1031-5 |arxiv=2003.11310 |s2cid=214641162 |url=https://www.nature.com/articles/s41567-020-1031-5 |access-date=9 October 2020 |language=en |issn=1745-2481 |display-authors=4}}</ref> Later work complemented this work by quantum-entangling two mechanical oscillators.<ref>{{cite news |first=Tim |last=Wogan |title=Vibrating drumheads are entangled quantum mechanically |url=https://physicsworld.com/a/vibrating-drumheads-are-entangled-quantum-mechanically/ |access-date=14 June 2021 |work=Physics World |date=17 May 2021}}</ref><ref>{{cite journal |last1=Lépinay |first1=Laure Mercier de |last2=Ockeloen-Korppi |first2=Caspar F. |last3=Woolley |first3=Matthew J. |last4=Sillanpää |first4=Mika A. |title=Quantum mechanics–free subsystem with mechanical oscillators |journal=Science |date=7 May 2021 |volume=372 |issue=6542 |pages=625–629 |doi=10.1126/science.abf5389 |pmid=33958476 |arxiv=2009.12902 |bibcode=2021Sci...372..625M |s2cid=221971015 |url=https://www.science.org/doi/10.1126/science.abf5389 |access-date=14 June 2021 |language=en |issn=0036-8075}}</ref><ref>{{cite journal |last1=Kotler |first1=Shlomi |last2=Peterson |first2=Gabriel A. |last3=Shojaee |first3=Ezad |last4=Lecocq |first4=Florent |last5=Cicak |first5=Katarina |last6=Kwiatkowski |first6=Alex |last7=Geller |first7=Shawn |last8=Glancy |first8=Scott |last9=Knill |first9=Emanuel |last10=Simmonds |first10=Raymond W. |last11=Aumentado |first11=José |last12=Teufel |first12=John D. |title=Direct observation of deterministic macroscopic entanglement |journal=Science |date=7 May 2021 |volume=372 |issue=6542 |pages=622–625 |doi=10.1126/science.abf2998 |pmid=33958475 |arxiv=2004.05515 |bibcode=2021Sci...372..622K |s2cid=233872863 |url=https://www.science.org/doi/10.1126/science.abf2998 |access-date=14 June 2021 |language=en |issn=0036-8075 |display-authors=4}}</ref>
