Quantum entanglement demonstrated in macroscopic objects

By David Pescovitz at 12:24 pm Friday, Dec 2

A pair of diamond crystals, large enough to be seen by the naked eye, have been linked together by quantum entanglement. The diamonds are entangled such that manipulating one affects the other, even though they are physically separated. In this case, the crystals were 3 millimeters wide and 15 centimeters apart. (One of the diamond wafers is pictured below.) Indeed, Einstein called this phenomenon “spooky action at a distance,” and scientists still don’t understand how it’s possible. The University of Oxford physicists published their work today in the journal Science. From Nature:

 Media Inline Room-Temperature-Entanglement 1A vibration in the crystals could not be meaningfully assigned to one or other of them: both crystals were simultaneously vibrating and not vibrating.

Quantum entanglement — interdependence of quantum states between particles not in physical contact — has been well established between quantum particles such as atoms at ultra-cold temperatures. But like most quantum effects, it doesn’t tend to survive either at room temperature or in objects large enough to see with the naked eye.

A team led by Ian Walmsley, a physicist at the University of Oxford, UK, found a way to overcome both those limitations, demonstrating that the weird consequences of quantum theory apply at large scales as well as at very small ones.

About anomaly

SMiles Lewis has had a lifelong interest in all things anomalous. An early age proclivity at recalling his nightly dreams as well as several personal experiences with ESP, precognition and dream switching bolstered his interest in the paranormal. Shortly after high-school he joined the local MUFON chapter in Austin, Texas. He would later become a MUFON State Section Director for that group as well as leader of the local UFO Experiencer Support and Study Group. A lover of books, SMiles collected over 1000 titles before founding the non-profit Anomaly Archives that serves as the lending library of the Scientific Anomaly Institute (501c3). For over twenty years he has worked with digital audio, video and other bleeding edge internet technologies. He has published his own print journal (E.L.F. Infested Spaces), edited a local paranormal newspaper (Austin Para Times), maintained a large network of websites (ELFIS.net), organized a national UFO conference (NUFOC-38), spoken to anthropologists about UFOs and parapsychology (Encounters with the Fantastic), hosted (and been a guest on) both terrestrial and webradio talk shows and has been podcasting since before the phrase existed. All these efforts and more have led radio talk show host Robert Larson to describe Miles as a “Gonzo Alt-Media Proprietor and Informationalist.” He is also the LOWFI-Texas State Bureau Chief of The League of Western Fortean Intermediatists. SMiles’ current projects include co-hosting PsiOp-Radio with Mack White as part of the many unique shows airing daily on his ANOMALY RADIO Network. He is active with several local non-profits which includes his service on the board of directors for the Institute for Neuroscience And Consciousness Studies (INACS) and the Scientific Anomaly Institute‘s lending library, the Anomaly Archives. His writings can be found within the Archives of his print journal ELFIS and ANOMALY Magazine. In his day job with the Texas State Library and Archives Commission‘s Talking Book Program he manages a Volunteer Recording Studio and audio duplication department and has been a consultant on two digital audio development documents for the Library of Congress‘ National Library Service for the Blind and Physically Handicapped.
