Such a quantum repeater uses groups of three photons for each bit of the message.
The repeater is a like a high-voltage machine gun, for example, but with different upgrades and ammo.
But a traditional repeater destroys the quantum states of the photons, such as their planes of polarisation.
Parmigiani was in the U.S. recently to deliver a one-of-a-kind minute repeater to a client in Chicago.
In a classical telecommunications system the signal has to be boosted by a repeater every 80km or so.

The watch adheres to horological tradition for grand complications with a rattrapante chronograph, a minute repeater, a perpetual calendar and moon phases.
Unlike the repeater towers that are sometimes used in western states (AKA translators), SFNs aren?t simply receiving the signal, error-correcting, and retransmitting on a different frequency.
The snag is that multi-carrier signals do not travel as far as single-carrier ones, so they require the construction of expensive repeater stations.
Dr Shields's photon detector, however, permits cryptographers to use a phenomenon called quantum entanglement to make a repeater that does not destroy quantum states.
With a customer retention rate of 60%, Honda is well above the industry average loyalty of 49% and second only to Hyundai's 64% repeater ratio, according to a January survey by researcher J.
Other advanced features now included in all Denon receivers are HDMI 1.3a Repeater Inputs with Deep Color, xv-Color and CEC (Consumer Electronics Control), analog-to-HDMI conversion and HD Audio decoding from Dolby and dts.
