Well , here ’s a cooooool finding . Take any piece of electronic equipment you may think of and its circuit are powered by , yes , electrons . But anew experimenttakes us one step closer to “ atomtronic circuits ” made of supercold quantum issue that can be reconfigured on the fly .
Scientists at Los Alamos National Laboratory started with clouds of atoms very close to absolute zero , a state of matter of matter called the Bose – Einstein condensation . These atom swarm have a special holding where they act as a quantum object . To make the circuits , the team just take lasers , which New Scientist explains :
Their circuits are establish from two laser beams , one that creates a horizontal sheet of lightness to dissemble as a circuit board , and another perpendicular optical maser that traces out the path of the circle . The condensation , which is made from around 4000 cool down rubidium speck , is entrap inside the beam by the same forces used to createoptical tweezers , which can manipulate particles on a small scale .
Unlike your average electric circle , which is made of tangible thing , this quantum tour is just made of light . That means we could redrawn the circuit while it ’s in use , allowing complex circuits to be packed into a small space , the researcherstellNew Scientist .
A like arrangement of condensates on optical maser is already being studied to create aquantum navigational arrangement for grinder , which ca n’t swear on GPS deep underwater . Someday , it could come in ready to hand on land as well . [ New Scientist , ArXiv ]
