    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…
