Entangled Photons data transmission

what is Entangled data transmision ?

a way to transmit data by modifying the properties of one of two entangled photons

How does it work

- two entangled photons are sent each to two  different devices .

-The polarisation of the two photons is not decided  until  the closest device is reached by the photon that was sent to it.

-The polarisation is decided by photon absorbtion in one of two adjustable states among many other possible states, acording to the data that needs to be sent.

- the polarisation of the second photons is read at the second device..



How are the photons transmitted ?

By optical fiber

Optical fibers can transmit photons to about 100km. Statistical counts of recieved photon states can help decide which information  was sent. 

Through freespace

Photons can also be sent though freepace, for instance from a satellite.  The main limitation on distance is then  set by the precision of the lens  transmitting  the photons.


Is distance between the two devices impacting transmission speed ?

Photons are entangled

The photons are entangled and therefore the polarisation of the second photons is immedaitely set according to the polarisation of the first photon whatever the distance between them.
