It is proposed that the eyes of European robins may naturally cultivate the conditions for quantum entanglement far better than the best artificially created laboratory systems, perhaps allowing them to “see” the magnetic field of the Earth; essentially suggesting that birds’ eyes may constitute biological entanglement-based compasses…

To me, the exciting aspect of this result (that entanglement exists between the future and past) is that it is quite a general property of nature and opens the door to new creativity…
University of Queensland physicist S. Jay Olson, to PhysOrg.com interviewer.
Article continues:
In “ordinary” quantum entanglement, two particles possess properties that are inherently linked with each other, even though the particles may be spatially separated by a large distance. Now, physicists S. Jay Olson and Timothy C. Ralph from the University of Queensland have shown that it’s possible to create entanglement between regions of spacetime that are separated in time but not in space, and then to convert the timelike entanglement into normal spacelike entanglement. They also discuss the possibility of using this timelike entanglement from the quantum vacuum for a process they call “teleportation in time.”

Is quantum mechanics messing with your memory?
Imagine if a cold cup of coffee spontaneously heated up as you watched. Or a cracked pane of glass suddenly un-broke. According to physicist Lorenzo Maccone at the Massachusetts Institute of Technology, you see things like this all the time – you just don’t remember.
In a paper published last week in Physical Review Letters, he attempts to provide a solution to what has been called the mystery of “the arrow-of-time.”
When you observe any system, according to Maccone, you enter into a “quantum entanglement” with it. That is, you and the system are entangled and cannot properly be described separately.
The entanglement, Maccone says, is between your memory and the system. When you disentangle, “the disentangling operation will erase this entanglement, namely the observer’s memory”. His paper derives this conclusion mathematically.
While we cannot remember our cups of coffee re-heating, and hence cannot study them, Maccone thinks that entropy-decreasing events like that must happen.
“If transformations that increase the entropy do occur – and we know that they do – by symmetry we should expect also transformations that decrease the entropy – but we cannot see them.”

Entanglement Try this great puzzle!

Quantum mechanics cannot be applied to macroscopic systems. (Like we humans, for instance.) But read the passage, and maybe replace a few words here and there, and we could be talking about two people and the connection between them. Quite a lovely concept, entanglement.

Ordered Chaos.: Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone
Does the Past Exist Yet? Evidence Suggests Your Past Isn’t Set in Stone
Recent discoveries require us to rethink our understanding of history. “The histories of the universe,” said renowned physicist Stephen Hawking “depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history.”
Is it possible we live and die in a world of illusions? Physics tells us that objects exist in a suspended state until observed, when they collapse in to just one outcome. Paradoxically, whether events happened in the past may not be determined until sometime in your future — and may even depend on actions that you haven’t taken yet.
In 2002, scientists carried out an amazing experiment, which showed that particles of light “photons” knew — in advance −- what their distant twins would do in the future. They tested the communication between pairs of photons — whether to be either a wave or a particle. Researchers stretched the distance one of the photons had to take to reach its detector, so that the other photon would hit its own detector first. The photons taking this path already finished their journeys -− they either collapse into a particle or don’t before their twin encounters a scrambling device. Somehow, the particles acted on this information before it happened, and across distances instantaneously as if there was no space or time between them. They decided not to become particles before their twin ever encounterd the scrambler. It doesn’t matter how we set up the experiment. Our mind and its knowledge is the only thing that determines how they behave. Experiments consistently confirm these observer-dependent effects.
More recently (Science 315, 966, 2007), scientists in France shot photons into an apparatus, and showed that what they did could retroactively change something that had already happened. As the photons passed a fork in the apparatus, they had to decide whether to behave like particles or waves when they hit a beam splitter. Later on - well after the photons passed the fork - the experimenter could randomly switch a second beam splitter on and off. It turns out that what the observer decided at that point, determined what the particle actually did at the fork in the past. At that moment, the experimenter chose his history.

It’s fascinating from a human point of view […], it’s interesting that no one until now was motivated to consider this kind of detector—you normally want to use the best detector possible, not something like the human eye.” Entanglement is usually thought of as a rather fragile phenomenon, he added, and such experiments could highlight that it is robust enough “as to survive a person detecting it—much stronger than people usually appreciate.
