Experiment tests Einstein's 'God does not play dice' with quantum
'dice'

Summary:Random number generators played a critical role in an historic
experiment. The experiment gives the strongest refutation to date of
Albert Einstein's principle of 'local realism,' which says that the
universe obeys laws, not chance, and that there is no communication
faster than light.

This is an artistic impression of the entanglement between electrons.
ICFORandom number generators developed at ICFO -- The Institute of
Photonic Sciences, by the groups of ICREA Professors Morgan W.
Mitchell and Valerio Pruneri, played a critical role in the historic
experiment was published online today in Nature by the group of Ronald
Hanson at TU Delft. The experiment gives the strongest refutation to
date of Albert Einstein's principle of "local realism," which says
that the universe obeys laws, not chance, and that there is no
communication faster than light.

As described in Hanson's group web the Delft experiment first
"entangled" two electrons trapped inside two different diamond
crystals, and then measured the electrons' orientations. In quantum
theory entanglement is powerful and mysterious: mathematically the two
electrons are described by a single "wave-function" that only
specifies whether they agree or disagree, not which direction either
spin points. In a mathematical sense, they lose their identities.
"Local realism" attempts to explain the same phenomena with less
mystery, saying that the particles must be pointing somewhere, we just
don't know their directions until we measure them.

When measured, the Delft electrons did indeed appear individually
random while agreeing very well. So well, in fact, that they cannot
have had pre-existing orientations, as realism claims. This behaviour
is only possible if the electrons communicate with each other,
something that is very surprising for electrons trapped in different
crystals. But here's the amazing part: in the Delft experiment, the
diamonds were in different buildings, 1.3 km away from each other.
Moreover, the measurements were made so quickly that there wasn't time
for the electrons to communicate, not even with signals traveling at
the speed of light. This puts "local realism" in a very tight spot: if
the electron orientations are real, the electrons must have
communicated. But if they communicated, they must have done so faster
than the speed of light. There's no way out, and local realism is
disproven. Either God does play "dice" with the universe, or electron
spins can talk to each other faster than the speed of light.

This amazing experiment called for extremely fast, unpredictable
decisions about how to measure the electron orientations. If the
measurements had been predictable, the electrons could have agreed in
advance which way to point, simulating communications where there
wasn't really any, a gap in the experimental proof known as a
"loophole." To close this loophole, the Delft team turned to ICFO, who
hold the record for the fastest quantum random number generators. ICFO
designed a pair of "quantum dice" for the experiment: a special
version of their patented random number generation technology,
including very fast "randomness extraction" electronics. This produced
one extremely pure random bit for each measurement made in the Delft
experiment. The bits were produced in about 100 ns, the time it takes
light to travel just 30 meters, not nearly enough time for the
electrons to communicate. "Delft asked us to go beyond the state of
the art in random number generation. Never before has an experiment
required such good random numbers in such a short time." Says Carlos
Abellán, a PhD student at ICFO and a co-author of the Delft study.

For the ICFO team, the participation in the Delft experiment was more
than a chance to contribute to fundamental physics. Prof. Morgan
Mitchell comments: "Working on this experiment pushed us to develop
technologies that we can now apply to improve communications security
and high-performance computing, other areas that require high-speed
and high-quality random numbers."

With the help of ICFO's quantum random number generators, the Delft
experiment gives a nearly perfect disproof of Einstein's world-view,
in which "nothing travels faster than light" and "God does not play
dice." At least one of these statements must be wrong. The laws that
govern the Universe may indeed be a throw of the dice.
