Spooky Experiments Bring Quantum Weirdness To Nearly Macroscopic Scales

Spooky Experiments Bring Quantum Weirdness To Nearly Macroscopic Scales

Experimenters around the world are trying to harness perhaps the most perplexing property in physics: Quantum entanglement, which Einstein called “spooky action at a distance”. A few teams of scientists have succeeded in bringing this eerie behaviour, which normally only exists between pairs of particles, to much bigger systems.

New Quantum ‘Cat State’ Can Be In Two Places At Once

Chances are you’re familiar with the Schroedinger’s cat paradox, whereby a hypothetical cat inside a box is both dead and alive until we open the box to see for ourselves. Now physicists at Yale University have figured out how to make a cat that both lives and dies in two…

Quantum Entanglement Can Now Be Performed On A Chip

The lure of quantum entangled computing is strong, as it can provide a means of impenetrable encryption — but the hardware has always been too bulky to make it practical. Now, though, researchers have shrunk the technology down to less than the width of a human hair, small enough to…
