Abstract
It is essential to establish precise times in future communication
networks. Any real-time task’s function depends on the system’s ability
to synchronise time. Time synchronisation is critical in the current
communication network and must be maintained to transmit data packets.
The functionality of 6G, the Tactile Internet, Time-Sensitive
Networking, and ultra-reliable low-latency communications is highly
susceptible to time synchronisation. We investigated the idea of
employing time synchronisation across different communication network
nodes. The current state-of-the-art employs network protocols like
Precision-Time Protocol for synchronising clocks across different nodes.
These network protocols are not robust and can generate jitters in data
transmission. In this paper, we suggested synchronising the time of the
node clocks at three different places using quantum technology. Notably,
the oscillation frequencies of each qubit (or oscillator) located at
these nodes can be synchronised using the quantum synchronisation
technique. This set of three oscillators will work as a single clock and
will be the master clock of the network. We propose distributing precise
time and frequency standards using quantum synchronisation on node
clocks. We can synchronise the three qubits (each placed at one node) to
oscillate at an identical frequency by applying an external field of a
wavelength of $813.32$ nm. We analysed our model for different
coupling constants and dissipation rates to provide an analysis of the
behaviour of the amount of synchronisation in different experimental
configurations. The optimal accuracy for our system is $1.6
\times 10^{15}$ signals per second. Further, we
used the Allan deviation to examine the stability of our system for
various noise strengths.
