QKD products

QUKY, the Quantum Key Distribution Platform by ThinkQuantum, provides BB84-based quantum-safe cryptographic keys with high quality in terms of security (QRN2Qubit direct stream), robustness and reliability. The QKD platform includes QUKY-TX (Alice) and QUKY-RX (Bob).

Key features

Key-rate

High key generation thanks to the lowest QBER provided by the embedded iPognac (patented solution)

Qubit4Sync

Efficient Qubit-based self-synchronization does not require additional fibers

True QRNG Stream 
QRN2Qubit direct stream (no pseudo-random, no expansion) from embedded QRNG to Qubit Preparation Stage

Robust & Reliable

Quick installation, robust and reliable devices coming with hot-swappable power supply system (1+1 redundant)

Protocol
QKD system based on BB84 protocol and polarization encoding
Networking
Our system enables the implementation of complex network topologies. Compatible with ETSI 014, ETSI 004
Modularity
Smart system designed to work with either fiber or free-space optical link

Interoperability 

Alice & Bob do not need to be matched: the same device can work with different units
Tailored solution
Flexible design for customized solutions (i.e. SPAD or SNSPD, co-existence of Quantum & Classical on same fiber)

EU27

ThinkQuantum, based in Italy with an Italian shareholder structure, offers a reliable European Supply Chain
