" Quantum entanglement is one of those strange facets of quantum mechanics that produces baffling behaviors in objects at the quantum level, but isn&amp;#039;t easy to find in our everyday world that appears to be governed by good old-fashioned classical physics. Yet, according to quantum theory, even objects in our everyday macro-size world should have this property. And in a new study in today&amp;#039;s edition of the journal Science, researchers have shown that they could entangle diamond crystals, the first time entanglement has been shown in objects under real-life conditions.  Quantum entanglement happens when two particles, such as photons or electrons, interact and become linked. Even when the particles are moved miles apart, the molecules&amp;#039; mechanical states (such as their spin, momentum, and polarization) remain mysteriously coupled. If the state of one entangled particle is changed, its faraway twin will be instantaneously affected. It&amp;#039;s a bizarre property Einstein famously called &amp;quot;spooky action at a distance.&amp;quot; This spooky property of matter has a powerful effect on the outcome of events in the quantum world. &amp;quot;In the classical world, chance outcomes have no strange correlations\u2014the events at one roulette wheel in a casino have no effect on events at the other tables,&amp;quot; says physicist Luming Duan from the University of Michigan, in a separate article in Science. But &amp;quot;in a quantum casino, we could imagine that roulette wheels are entangled, so that if one ball dropped on a black number, the ball at the next table must drop on red.&amp;quot; Another strange thing about entanglement: The information seems to travel faster than light between the two objects, breaking the universe&amp;#039;s apparent speed limit. Scientists have been able to entangle particles in the lab before, but only under special conditions, by isolating them and cooling them to ultra-low temperatures. &amp;quot;What we did was to demonstrate that you could make these wacky states in these everyday normal objects sitting in a regular laboratory under no particularly special conditions,&amp;quot; study author Ian Walmsley says. To do this, his team used a laser to start the crystals of a millimeter-size diamond vibrating. The vibrations were reflected in the diamond&amp;#039;s entangled twin a few centimeters away. The researchers used ultra-fast optical technology to create and measure the entangled state before it broke up. It was this fast detection that made the diamond entanglement experiment possible. Most physicists, Walmsley says, believe that quantum entanglement is a property present in all objects in our macro world; we just don&amp;#039;t see it happening. &amp;quot;In the everyday environment, objects are connected to other objects,&amp;quot; he says. &amp;quot;They&amp;#039;re sitting on the floor, wafting in the wind, and those connections are ways in which information and energy can leak out of one system into another.&amp;quot; So objects lose their entanglement quickly. By using super-speedy technology, this team caught the diamonds acting entangled before environmental interactions overcame the effect.  Walmsley says that future experiments will focus on getting the quantum interactions to hang on longer, and in bigger objects. The bigger the objects gets, the harder it is to home in on quantum interactions. But, he says, to put quantum entanglement to technological use, it has to be done.  One dream is to use quantum entanglement to create super-powerful quantum computers. Quantum computing would use a new fundamental design based on the properties of quantum mechanics, which would basically allow these computers to &amp;quot;explore a great number of options simultaneously in a very efficient way,&amp;quot; Walmsley says. But because a computer is a hefty, macroscopic thing, to to build a practical quantum computer, scientists will have to create entanglement on a much bigger scale.
