To counter the many issues that prevent existing IoT solutions from finding their full potential,
we outlined our strategy for building a solution that can.
Look here if you'd like a more in depth look at the implementation of our solution.
We use Quantum Key Distribution (QKD) protocol to implement a cryptographic protocol that enables us to produce and secretly exchange a key between two distant parties in order to encrypt and decrypt messages. The advantage of QKD is the ability of the two communicating users to detect any third party attempting to intercept or gain knowledge of the key. The information is transmitted in quantum states through quantum entanglement that is able to detect eavesdropping.
qIoT devices would have a quantum
transmitter or receiver onboard to enable quantum communication (QC).
The transmitter is a photonic integrated circuit that contains a quantum state encoding engine that is able to encode multiple phase states with phase values and random numbers. An optical attenuator and DFB laser is also included, combining gain-switching, injection locking and quick phase modulation to generate pulse trains for the phase encoded photons. The encoded pulses of the photons are transferred out to a fiber and transmitted over the quantum channel.
The receiver on the other side of the channel consists of silicon oxynitride and is made up of a Photonics circuit with thermo-optic phase shifters and single photon detectors. The receiver sends the input signal from the transmitter to the single photon detectors for key generation and visibility measurement.
these are implemented for longer distances, breaking up the transmission distance into segments to avoid photon loss. The repeater performs the QKD in several segments then establishes an entangled photon pair between the nodes next to each other. The repeater contains
We use a satellite platform and space-based link to connect two remote points on Earth by means of photons encoding messages. More satellites would create a larger network. The satellite produces entangled photon pairs and uses QKD to relay the message, which are broadcasted to two different base stations on the ground. Once on ground the photons are directed into quantum memories where secure messages are then sent locally through optical fibers.
