Recently, scientists were able to "teleport" photons to a satellite 300 miles away, using "quantum entanglement." This is where a pair of photons are able to simultaneously share the same state, even when separated by distance. Change the state of one particle, and the other changes too.
Teleportation can have big implications for a new “quantum internet.” It will be faster, more powerful, unhackable.

Human teleportation may be possible within 100 years. The transport of a simple molecule may be possible in the next 10 years, followed by DNA.
Perhaps warping spacetime could count as a method of teleportation, similar to the folded paper analogy, where you bring two distant points together by simply "folding" spacetime dot-to-dot to create an Einstein Rosen Bridge. However, it is entirely theoretical.
But, maybe teleportation is a step too far - just because you can think it, doesn't mean you can do it.
Scientists are still working out how to teleport photons. Assuming they figure out how to teleport atoms, then molecules, the amount of bits to record and transmit, is unthinkable.
A person is made of an estimated 32 trillion cells. They would require a huge bandwidth and roughly 10th gigawatt-hours of power. Teleporting one person would require using the entire UK power supply for more than a million years and take 4.8 million million years to transfer - that is if you survive the transfer. It would be quicker to walk.
Teleportation is the idea in which we step into a sort of scanner and instantaneously find ourselves somewhere else.
There are two ways this can'(t) be done: physical deconstruction at x and reconstitution at y or the translation of one's person into data to be transmitted, and then to be reconverted into matter (like some sort of fax machine).
Quantum Entanglement is a phenomena that describes how the measurements of spin, momentum, and position can all be same between two unique particles.
The main issue is that entanglement can only exist for brief moments because any sort of observation or change in environment can break it.
Entanglement is interesting because it can fit well into other theories as well. One example is Hawking Radiation. The very premise of the theory is that an Entangled Photon Pair is separated at the surface of a Black Hole.
How interesting would it be if humans could be entangled with each other?
Stepping out into the universe... we must confront the reality of interstellar travel. We must reach far beyond our own lifespans.
Scientists at the Large Hadron Collider have recently studied how, imbued with enough energy, photons can bounce off of one another like massive particles do. Scientists at the LHC and the Relativistic Heavy Ion Collider have also reported seeing photons colliding and converting that energy into massive particles.
The photon’s most recent seemingly impossible feat? Smashing so hard into a lead nucleus that the collision seems to produce the same state of matter that existed moments after the Big Bang.
