I just read this paper and it was very interesting. The paper is called "Experimental Test of Quantum Histories" http://arxiv.org/abs/1601.02943
Here's some of an article about the paper.

I have been reading a lot lateley about these Temporal Correlations and some Scientist are saying they are the foundation of reality that give rise to spacetime.
The way I read it, is that there's correlation between events in time.
I wanted to make sure I had this right. Are they saying that events in time are correlated so these events don't take any causual or sequencial order?
To extrapilate this to a classical level, it would be like going to the store, Doctor and to a restaurant but all of these events occur essentially at the same time because there's no sequencial order of events. It ended this way.
Here's some of an article about the paper.
Nobel laureate Frank Wilczek at MIT and colleague Jordan Cotler, now at Stanford University, provide evidence for what they call entangled histories in a paper posted online January 12 at arXiv.org. The researchers proposed and collaborated on an experiment that started and ended by measuring a particular property of a photon; in between, the experimenters subtly probed the photon without disturbing its delicate quantum state. The head-scratching result was that there was no way to create a single chronology that could describe how the photon changed. Instead, there must be multiple chronologies that are entangled, sharing a quantum connection usually reserved for groups of particles rather than chunks of time.
“There really is something very deep going on here about the nature of quantum mechanics and time,” Cotler says. “Our best description of the past is not a fixed chronology but multiple chronologies that are intertwined with each other.” The experiment may offer a new means of exploring and interpreting quantum weirdness.
Yet Cotler and Wilczek suspected that it wasn’t so simple. In a paper last year, they introduced the idea of entangled histories, cases in which a single chronology is insufficient to explain the observed changes in the properties of a particle. Just as the understanding of an entangled particle is impossible without considering its partner, the history of a particle could be incomplete without the existence of multiple entangled timelines.
Just as Cotler and Wilczek expected, the experimenters couldn’t formulate a chronology that was consistent with both the starting and ending measurements of each photon and the mirror-based evidence in between. The only way to reconcile all the observations, Cotler says, is to conclude that the photon went through multiple histories in parallel. When the researchers made the final measurement of the photon, those alternate timelines merged.

Wilczek is far more optimistic. He calls the experiment “a rather direct realization” of a 60-year-old interpretation of quantum mechanics known as “many worlds,” in which measuring photons and other environmental interactions split reality into alternate timelines. Sometimes the different branches are consistent on their own and remain separate, Wilczek says. But in this case, the separate chronologies are intertwined and eventually come back together. “The deepest and most appealing aspect of this experiment,” he says, “is that it allows you in a mathematically precise way to nail what exactly many worlds is about.”
