Quantum teleportation is the process of transporting quantum information to a new location while destroying it at it’s starting location. Recent revelations within this field have conjured up ideas on transporting people across the world in an instant, with readers convinced that teleportation will be a future method of transportation.
Overview of Quantum Teleportation
However, what we are really considering is the idea that information can be transmitted to another location using a system that reassembles a scan of the original data elsewhere with new materials. This form of teleportation is possible because of quantum entanglement, which is a form of quantum mechanics.
In this system, entanglement occurs as a result of particles being forced to hold mutually exclusive states. If we then send one of the entangled particles to a different location to transport something between them, all you would need to do is entangle the object with these particles.
Potential Applications of Quantum Teleportation
Scientists are particularly interested in developing this process because it opens the doors to numerous applications, most namely relating to the creation of quantum communication networks which would be safe from hacking, and quantum computing protocols.
While developments are still in their infancy, numerous studies have shown that quantum teleportation technology is within our reach, with recent research taking a significant step forward through involving semiconductors in the methodology.
A decade ago, a team of researchers in Italy wasable to show that anefficient teleportation process was possible, through building a network of communicating semiconductor quantum wires, which created gates for quantum information processing.
Recent Developments
Following this, back in 2013, a British team of researchers at the University of Cambridge, and at Toshiba Research Europe Limited, were able to teleport photonic qubits from pairs of entangled photons successfully. The advancement they made was in using photons generated by LED light with an embedded quantum dot. Quantum dots are a form of a semiconductor, made of crystal of nanometre dimensions.
The implications of their findings were that their use of a semiconductor demonstrated an advantageous way of implementing quantum teleportation over previous methodologies that generated entangled photons using a laser. The researchers noted that photonic qubits were the best option for creating quantum teleportation systems to be used in the largest number of applications.
More recently, in 2017, researchers based in the Republic of Korea proposed another quantum teleportation scheme that also utilized quantum dots. The methodology used interactions between flying photons and quantum dots within both single and double-sided cavities, to successfully teleport an unknown state. What was groundbreaking with this research was that the proposed quantum dot-cavity based methodology was able to be fully realized with current technologies. This means that development of the process within various applications is possible to go ahead right now.
Finally, last year, a team of experts from Austria, Italy, and Sweden conducted a study that successfully demonstrated the use of on-demand photons from quantum dots. The research addressed the limitations that have faced quantum teleportation up until this point. Previous studies have difficulties in amplifying quantum signals in order to support teleportation. The solution they came up with was to generate photons on-demand as part of a quantum repeater, using semiconductor quantum dots.
Conclusion
While there is much work still to be done in this area, experts are certain that in a few more years, we will be seeing this process being used in real-world applications within various global industries.
