Is it possible to be here... and here... at the same time?
By this I mean, is it possible for something to be in two places simmultaniously?
Sure, just travel back in time, and then meet yourself in the past or the future.
Yes it is possible in the Quantum world for one entity to occupy two (or more) spacetime coordinates.
In an effort to mathmaticly define the location of electrons in an atom, physics spawned a whole new genre of study in the atomic level of matter called quantum physics. Experiments have proven that en electron is equally probable to be in multiple locations simultaneously. These location probabilities describe energy fields. Many different theories that describe various dimentions have emerged such as string theory. But they all tend to collapase when the hypothesis is applied to the big bang theory at the moment of the big bang and just before it.
Then came along the eleventh dimention, the Membrane Theory. This suggests that there is an infinate number of parrallel universes, each with it's own unique set of atributes and binds matter together with membranes (instead of strings as in string theory). Each one of these universes can be visualized as different shaped bubbles. These membranes can elongate and surround other membrains. In fact the big bang could have been caused by two ends of a membrane colliding and trying to occupy the same same space at the same time.
So yes, things can be in multiple places simultaneously. Just don't get two instances of the same thing in the same location at the same time.
Further details available at 4:20.
It's interesting to wonder how many theories that there are to explain such a question. Yes we can occupy two places but there are many different ways this can be accomplished.
So much we are yet to understand
Does it not depend on what to be is what?
Sure if you are talking about particles that is one thing but talking about real life bodies is another. If some science buff comes up with a 'theory' that particles can transverse space and time then how does that apply in real people worlds where human frail bodies could not survive the trip?
If the context of the question and answer applies to particles then that is one thing but if it applies to real human exsistence then thats another.

Wasn´t that one of the miracles of St. Nikolaus? <gd&r>
Well, the answer to your question really just depends where here is, and where here is. If here is "in my bedroom" and the other here is "in the hallway", then the answer is yes. Put your foot one foot in the hallway and the other in your bedroom. If it's more complex, such as the first here being "in Africa around 156 BC" and the second here being "on Planet X in 4387 AD", then you open an entire new door to scientific theories.

In fact, I believe quantum tells us that EVERYTHING is in more than one place.

Sort of. The wave-function describes everything as having a 'probable' spacetime co-ordinate which is only 'collapsed' when measured (that would be the classic Copenhagen interpretation). More modern interpretations place more emphasis on decoherence (interference with the 'macro' world) rather than wave-function collapse.
Of course, according to Wave Functions in Quantum Mechanics, a particle can occupy different places at the same time. But these are generally limited to tiny particles and not "entities" as it were. So, I wouldn't say that you could be in one place at once and another at the same time. Again, you're talking pseudo-science here.
And ... what about Schrodinger's Cat according to which a cat can be dead and alive at the same time? Although it is paradoxical, it is in accordance with Quantum Mechanics. I actually have a very rudimentary understanding of this paradox. Could someone elaborate on this please ...
The 'paradox' is resolved in modern physics by 'decoherence'. Basically as elementary particles (and larger 'groups') interact with the environment, this gives the appearance of 'wave function collapse'.
