Einstein\u2019s \u201cspooky action at a distance\u201d persists even at high accelerations, researchers of the Austrian Academy of Sciences and the University of Vienna were able to show in a new experiment. A source of entangled photon pairs was exposed to massive stress: The photons\u2019 entanglement survived the drop in a fall tower as well as 30 times the Earth\u2019s gravitational acceleration in a centrifuge. This was reported in the most recent issue of Nature Communications<\/i>. The experiment helps deepen our understanding of quantum mechanics and at the same time gives valuable results for quantum experiments in space.<\/p>\n

Einstein\u2019s theory of relativity and the theory of quantum mechanics<\/a> are two important pillars of modern physics. On the way of achieving a \u201cTheory of Everything,\u201d these two theories have to be unified. This has not been achieved as of today, since phenomena of both theories can hardly be observed simultaneously. A typical example of a quantum<\/a> mechanical phenomenon is entanglement: This means that the measurement of one of a pair of light particles, so-called photons, defines the state of the other particle immediately, regardless of their separation. High accelerations on the other hand can best be described by the theory<\/a> of relativity. Now for the first time, quantum technologies enable us to observe these phenomena at once: The stability of quantum mechanical entanglement of photon pairs<\/a> can be tested while the photons undergo relativistically relevant acceleration.<\/p>\n
