Can teleportation truly occur based on scientific reasoning? Here's the scoop.
In the realm of science fiction, the concept of human teleportation has long been a popular theme, with shows like Star Trek depicting instant transportation of human beings from one location to another via teleportation machines. However, the reality of this phenomenon is far from the instantaneous and energy-efficient process portrayed on screen.
The major hurdle in achieving human teleportation lies in the transmission of the required information. To teleport a human, a transporter must pin down the position and type of every atom in a person's body. This task, as you can imagine, requires an immense amount of data. In fact, billions of times more information is required to transmit the makeup of a human being compared to reconstructing a TV image.
The energy requirements for this process are impractical, as pointed out by Arthur C Clarke. Ultra-short pulses of light, which are necessary for the transmission of this data, require an amount of energy that is more than what is found in a galaxy of stars.
On the other hand, physicists have made strides in the field of quantum teleportation. Developed by Charles Bennett and his team in 1993, this method allows for the creation of a perfect copy of a quantum particle at a remote location. This process, known as 'quantum teleportation', involves the transfer of quantum information from one particle to another without the physical transport of the particles themselves.
More recently, this method has been expanded to 'quantum telecloning', a process that can now be performed at multiple locations. However, it's important to note that these quantum processes only work with quantum particles, not with humans.
The speed of light is considered the fastest speed at which information can be transmitted. Therefore, Star Trek-style teleporters are unlikely to appear anytime soon due to the energy requirements for ultra-short pulses of light.
While human teleportation as depicted in movies and shows may seem like an exciting prospect, the challenges and impracticalities of the process make it more of a fascinating concept for discussion than a viable reality for the near future. For now, we'll have to stick to traditional methods of travel, whether that's a journey from the UK to the Sydney Opera House by plane or by boat.
