Two professors from the University of Oklahoma<\/a>, Arne Schwettmann and Grant Biedermann, have received $584,814 to fund research into what Albert Einstein called “spooky action at a distance.\u201d<\/p>\n The three-year grant was provided by the Defense Established Program to Stimulate Competitive Research<\/a>, a programme led by the US Department of Defense.<\/p>\n Schwettmann, a professor in the Homer L. Dodge Department of Physics and Astronomy<\/a>, said their research uses nearly 20,000 atoms within a gas that is cooled to extremely low temperatures. This cooling allows Schwettmann and Biedermann to study quantum entanglement, offering applications for quantum-enhanced sensing<\/a>.<\/p>\n “In an atomic sodium gas cooled to ultracold temperatures, atoms behave like small magnets that change their orientation when they collide with each other.<\/p>\n \u201cIn a gas at room temperature, the collisions happen randomly and uncontrollably, but if the sodium gas cloud is cooled all the way down to about 0.00000001 degrees above absolute zero temperature, the collisions happen predictably and can be controlled via microwaves.<\/p>\n \u201cThe atomic magnets become correlated in this process. This correlation is what Einstein called ‘spooky action at a distance\u2019, now known as quantum entanglement,” Schwettmann said.<\/p>\nResearch at extremely low temperatures<\/h3>\n
