The rhythm of the soul is influenced by mind and by action. The soul has not got its own rhythm. As in a higher sense the soul is pure from all things which can be distinguished and divided. One may ask, how then can it happen that the rhythm of the soul is lost? But if we see our friend in great grief we also will feel grief. It is not because we have a grief ourselves. We feel it only because our friend is in grief and this reflects on us. The soul is not subjected to a right rhythm or a wrong rhythm, but a right rhythm or a wrong rhythm can be reflected in the soul. For instance when a person says of something that it is ugly, what is ugly is outside of him. Then why does he feel discomfort or ugliness? Because it reflects upon him. For the moment while he is looking at the ugly thing, that ugly thing is in his eyes and in his mind. Just as when we are standing in front of a mirror our image is not engraved upon the mirror but is only reflected there; and it will remain there as long as we are standing before it. Thus the soul may experience misery or wretchedness, a wrong rhythm or a right rhythm, but when these are removed the soul is again free from them. In order to maintain a perfect condition in life one must be the master of rhythm.
Scientists at the Delft University of Technology's Kavli Institute of Nanoscience managed to transfer information contained in one quantum bit, or qubit, to another "entangled" qubit about 10 feet away "without the information having travelled through the intervening space," Prof. Ronald Hanson, head of the research group wrote in a summary.
In other words, as Hanson noted, "teleportation."
The Dutch researchers reported that there was no degradation in the information transferred between the two quantum bits, potentially a major advance in the pursuit of quantum teleportation. In the past several years, other scientists around the world have devised ways to better measure the information contained in qubits without altering them in the process and managed to teleport information "instantaneously" across distances as great as 90 miles.
Hanson's team plans to repeat their quantum teleportation experiment with qubits separated at longer distances, up to nearly a mile. The researchers fashion their qubits using electrons in diamonds, they said.
"We use diamonds because 'mini prisons' for electrons are formed in this material whenever a nitrogen atom is located in the position of one of the carbon atoms. The fact that we're able to view these miniature prisons individually makes it possible for us to study and verify an individual electron and even a single atomic nucleus," Hanson said.
"We're able to set the spin (rotational direction) of these particles in a predetermined state, verify this spin and subsequently read out the data. We do all this in a material that can be used to make chips out of. This is important as many believe that only chip-based systems can be scaled up to a practical technology."
Quantum entanglement allows for entangled particles like qubits to immediately share information even if separated by great distances in a seeming loophole in the universe's speed limit, the speed of light. Entanglement was famously described by Albert Einstein as "spooky action at a distance," and Hanson called it "arguably the strangest and most intriguing consequence of the laws of quantum mechanics."
"This development is an important step towards a quantum network for communication between future ultra-fast quantum computers—a quantum Internet," he said. "Quantum computers will be able to solve certain important problems that even today's supercomputers are unable to tackle. Furthermore, a quantum Internet will enable completely secure information transfer, as surreptitious eavesdropping will be fundamentally impossible in such a network."
Hanson and his team have published their findings in the current issue of Science.
