physics is even stranger than that

Brukner, Taylor, Cheung and Vedral, of London's Imperial College, mathematically demonstrate that quantum entanglement in time is possibly just as real as entanglement in space. They even posit that while quantum nonlocality is "monogamous"--i.e., one particle in space is entangled only with one other particle--temporal entanglement can be "polygamous." In their words:

...two maximally entangled events can still be maximally entangled to two other events in time.... [I]t may be an indication that we need a deeper theory... [I]t appears that the next step should lie in exploring the consequences of combining entanglement in space and time in order to study how they relate to each other.

Apparently, one possible practical application would be to use temporal entanglement to boost the efficiency of RAM. Weird, weird, weird.
