World first Quantum teleportation operation

Quantum teleportation was a dream and now the dream is close to be true, that's what a group at the University of Tokyo manged to get, a World first successful Quantum teleportation operation of photonic quantum bits by a hybrid technique, a step for a long long way to make this operation practical in real-life, the good news is that the new results show that the achieved teleportation efficiency is 100 times higher than before.


"In 1997, quantum bit teleportation was successfully achieved, but as I said just now, it was only achieved in a probabilistic sense. In 1998, we used a slightly different method to succeed at unconditional, complete teleportation. But at that time, the state sent wasn't a quantum bit, but something different. Now, we've used our experimental technology, which was successful in 1998, to achieve teleportation with quantum bits. The title of our paper is "Hybrid Technique," and developing that technique is where we've been successful."
The researchers successfully converted the quantum bit information into light wave, the device looks quite big with lot of light wave processing stages, but the team looks forward to combine all the devices in one small device.


"I think we can definitely say that quantum computers have come closer to reality. Teleportation can be thought of as a quantum gate where input and output are the same. So, it's known that, if we improve this a little, the input and output could be produced in different forms. If changing the form of input and output like that is considered as a program, you have a programmable quantum gate. So, I think a quantum computer could be achieved by combining lots of those."
