This will be very useful in progressing the field of quantum computers and communication.
Researchers at the Max Planck Institute of Quantum Optics set a new record after achieving a quantum entanglement of 14 photons, the largest on record so far, anQuantum entanglement, famously described by Albery Einstein as "spooky action at a distance" is a phenomenon where particles become intertwined in such a way that they cease to exist individually, and changing the specific property of one results in an instant change of its partner,Even though science fails to explain this,...
Researchers at the Max Planck Institute of Quantum Optics, therefore, set about to achieve this. They placed a single rubidium atom in an optical cavity so that it be bombarded with light particles and bounce off electromagnetic waves. When the atom was struck by a laser at a particular frequency, it prepared it to have a certain property. Then a separate control pulse was beamed at it, which caused it to emit a photon that was entangled with the atom.
The process was then repeated until a whole chain of photons was produced that were all entangled with each other. Between each emission, the atom was rotated which helped in the entangling of the 14 photons, the press release said. The researchers claim not only claim that this is the largest number of photons entangled with an atom in a laboratory but also that it is the most efficient process developed so far, with a 43 percent source-to-detection efficiency.In plain speak, it means that for every second push of the button to fire a laser, the researchers were able to generate, one photon of light that could be used for a specific application.

'I would certainly never have humiliated myself enough to reach out and ask for help and say, 'You know, I'm hungry. Can I have that apple that you're not going to eat?' I didn't have the courage to do that.'
