    75 years of entanglement

    Though it has been confirmed numerous times since 1935, entanglement is as spooky as ever.

    1935: Physicists Albert Einstein, Boris Podolsky and Nathan Rosen publish a paper in Physical Review asking “Can quantum-mechanical description of physical reality be considered complete?” Their answer: no.

    The same year, in the journal Naturwissenschaften, Erwin Schrödinger coins the...

    Quantum weirdness

    Quantum weirdness

    Some key concepts in quantum mechanics lead to rather startling results. In the quantum world, objects can be in two states at once and the outcomes of experiments can change depending on when, how and how often scientists make their measurements.

    Double-slit experiment An electron can be either a wave or a particle depending on the design of the experiment....

    Like fate of cat, quantum debate is still unresolved

    In the tapestry of 20th century physics, virtually every major thread is entangled with the name of Albert Einstein. He was most famous for the theory of relativity, of course, which rewrote Newton’s laws and set modern theoretical cosmology in motion. But Einstein also played a major role in the origins of quantum theory and in perceiving its weird implications — including entanglement, a...

    Everyday Entanglement

    If the Manning brothers were quantum physicists as well as NFL quarterbacks, one of them could win his game’s opening coin toss every time. The night before they played, the brothers would take two coins from a special quantum box to use the next day. If Peyton’s game came first, after learning the outcome of his coin toss, he would know without a doubt how his brother’s coin would land. Say...
