Physicists Simulate Time Travel Using Quantum Entanglement
The quantum world operates by different rules than the classical one we buzz around in, allowing the fantastical to the bizarrely normal. Now, a team of physicists has used quantum entanglement to simulate a closed timelike curve—in layman’s terms, time travel. Before we proceed, I’ll stress that this was simulated; no quantum particles went back…

Physicists Caught Two Atoms ‘Talking’ to Each Other
A team of physicists in the Netherlands and Germany recently placed a bunch of titanium atoms under a scanning tunnelling microscope. Those atoms were in constant, quiet interaction with each other through the directions of their spins. In a clever feat, the researchers were able to home in on a single pair of atoms, zapping…

Physicists Entangled Photons In The Lab With Photons From The Sun
In a classic physics experiment, scientists set up quantum entanglement between sunlight and light generated here on Earth.

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.
