Information Has Been Successfully Teleported For The First Time At A Temperature Near Absolute Zero Point. For the first time in history, scientists managed to teleport information from one point to another. In an experiment conducted in Switzerland, 10,000 bits of information per second were transferred from point A to point B in a solid state circuit similar to a computer processor.
'Teleportation', that is, teleportation, which we encounter only in science fiction movies in life, has become reality for the first time. In the experiment conducted at the Feeral Institute of Technology (ETH) in Zurich, 10,000 bits of data per second were teleported between points A and B, which were 6 millimeters apart.
While the achievement does not yet apply to massive creatures/objects such as humans, as we saw in Star Trek, it provided an important example of the incredible processing power that can be achieved with quantum computers in the future.
In the study, published in the journal Nature, scientists placed three micron-scale electronic circuits on a 7×7 mm computer processor. Two of the circuits acted as the sender mechanism, while the remaining one acted as the receiver.
In the experiment, the processor was cooled to near absolute zero, and then current was passed through the circuits.
Absolute zero represents the point at which no more heat can be drawn from a system, according to the thermodynamic heat scale. At this temperature, known as 0 K or -273.15 C, it is assumed that no individual molecules can move.
QUANTUM COMPUTERS IMPORTANT STEP
In the experiment, performed on an extremely small scale and in the freezing cold, the electrons in the circuit (quantum bits called qubits) began to react according to quantum mechanics. The qubits that became entangled, that is, connected, began to exhibit the same quantum state even when they were physically separated from each other.
In the experiment, the qubits in the transmitting circuit became confused with the qubits in the receiving circuit. The EHT team encoded information into the qubits in the sending circuits, then measured the quantum state of the qubits in the receiving circuit. The researchers found that the quantum states of the qubits in the sending circuit were instantly transferred to the receiving circuit. In short, the information was teleported between the two circuits.
The method performed is very different from what computers do, which carries electrons through the air via wires or radio waves. In the experiment at the EHT, not a single piece of data physically moved far. On the contrary, it disappeared at one point and appeared at another.
In similar experiments in the past, the transfer of quantum bits was done for greater distances, but the efficiency was very low. The experiment at the EHT achieved a performance that would allow quantum computers to be built by teleporting 10,000 bits of data per second.
