WHAT IS QUANTUM ENTANGLEMENT, ESPECIALLY IN TERMS OF TELEPORTATION?

If I have two electrons arriving in unison and then separate them, an invisible umbilical cord emerges, connecting the two. If I jiggle one, the other particle somehow senses the presence of what is happening to its twin. This sensing process goes faster than the speed of light. Einstein hated this process, and he actually used it to try and disprove quantum mechanics. Einstein was wrong. We can do this experiment in the laboratory. However, Einstein had the last laugh, because it turns out that usable information cannot be transferred this way. The information transmitted is random. However, some scientists say that if you go below the speed of light, then quantum teleportation may be possible at sub-light speeds.

Quantum teleportation is a little bit different to what you see in Star Trek! We’re talking about information travelling from one point to another point. We’ve done this with atoms and photons – we can teleport particles over hundreds of feet – so quantum teleportation is possible, but only at the subatomic level. You’re not going to have a transporter like in Star Trek.

1 Emitting the entangled photon

The spin of the photon will remain unknown until its counterpart’s identity is revealed.

2 Remaining unknown for the journey

The photon travelling away from Earth, most likely to

Welcome
On 28 June 2012, I was browsing the newsstand in my local WHSmiths in Tonbridge. I was on my lunch hour as a staff writer at Astronomy Now when I saw the very first issue of All About Space. The rest, they say, is history. Fast forward to November 20
