What is Quantum Computing ?
• Superposition is essentially the ability of a quantum
system to be in multiple states at the same time —
that is, something can be “here” and “there,” or “up”
and “down” at the same time.
• Entanglement is an extremely strong correlation
that exists between quantum particles — so strong,
in fact, that two or more quantum particles can be
inextricably linked in perfect unison, even if
separated by great distances.

Q-Secure Net will provide a cost effective
and flexible solution for UNCONDITIONALLY
SECURE COMMUNICATION SERVICES
based on Quantum Key Distribution (QKD)
on current metropolitan fiber-optic networks.
A novel blockchain application based on the
secure network platform will be also
implemented

Quantum key distribution
QKD uses quantum mechanics for
transmitting a sequence of bits
between two points.

European & others
The global QKD market is expected to grow over $980 million by 2024. In the long term, the QKD will be
strategic for the design of new architectures in many sectors like telco, defence and transports and
5G. QKD's infrastructural security and its ability to mitigate cyber-risks, also allow a whole new class of
approaches and applications for Decentralised Finance.

SYMMETRIC TIMESTAMPS & KEYS
THE EXCHANGE OF INFORMATION (KEYS, HASHTIMELOCK) AMONGS
VASPS NODES MIGHT BE SECURED BY QKD IN ORDER TO ALLOW
INTEROPERABILITY OF DIFFERENT BLOCKCHAIN NETWOTKS
Central Exchange allowing the conversion of cryptocurrencies
among heterogeneous blockchains have resulted to be neither
resilient nor able to scale.
In the recent exploration, Decentralized Exchange (VASP nodes)
have been proposed to tackle to improve the overall capability of
decentralized finance ecosystem

Applications
Interoperability of “chains”, like in Financial scenarios
for exchange of cryptocurrencies.
In future, possible to investigate application in Telco & I. SWAP over QKD
