Quantum Communication Technologies

Quantum Communication Technologies are definetely one of the hottests topics we are facing nowadays, with several different apparatuses meant to work together thanks to a multidisciplinary team orchestrating every mechanism synergically.

Our expertise ranging from engineering to physics allows us to integrate both classical and quantum optics into hardware solutions and software applications. This know-how is exploited to build up quantum key distribution and quantum random number generation systems. Devices are, but not limited to, electro-optical modulators, polarization beam splitters, fiber patches, single photon detectors, lasers, field programmable gate arrays, systems on a chip, analog-to-digital converters.

The integration of these components brings to the cration of QKD transmitters, capable of creating and send qubits according to an initial classical digital string. QKD receivers, are able to readout the transmitted qubits and store a digital string to perform post-processing. QRNGs, consent the generation of true random numbers out of quantum phenomena.

At ThinkQuantum our team of scientists works together to share expertise and know-how and give life to Quantum Communication.

Fiber-based Quantum Key Distribution (QKD)

Fiber optics represents the backbone of our modern communication systems with ubiquitous use from data center interconnecting to long haul links.

In many cases these links are used to transport highly sensitive information. In such cases QKD could be an ideal solution to encrypt the data with the highest level of security. Furthermore, QKD represents a future proof solution, since it is invulnerable to advances in quantum computing, computer sciences or mathematics.
At ThinkQuantum we have developed QKD systems that reduce the resources required for its deployment, simplifying the integration of the system with pre-existing fiber optics communication networks. Furthermore, ThinkQuantum uses patented state-of-the-art optical schemes that guarantee record-setting performances in terms of source-intrinsic Quantum Bit Error Rate and temporal stability.

Free-space Quantum Key Distribution (QKD)

Free-space quantum communication allows for a point-to-point link between two locations, without the need of an optical fiber.

This is the best solution for those locations that are not reached by the fiber infrastructure, or for those applications that require fast and/or not-permanent deployment of a quantum communication link. It is also the only solution for communication with moving platforms such as drones, high-altitude platform, aircrafts, ships.

At ThinkQuantum we have gathered the know-how to develop and deploy free-space quantum communication terminals that guarantees full-day operation. Our terminals can be used for one-way or two-way quantum communication, connecting two optical fibers over the air, thus avoiding trusted nodes among the peers, and allowing compatibility with standard telecom quantum communication devices.

Our system can be fully integrated with our quantum key distribution device but is also compatible with third-party quantum communication systems.

Space Quantum Communication

Long-distrance communications requires to overcome the unavoidable losses of fiber-based implementations, which are therefore limited to few hundreds of kilometers.

Since the technological maturity of the quantum repeater is still far away from concrete applications, the most effective way to extend quantum communication and QKD to the global scale is to use satellites and ground stations exchanging single photons.

Space quantum communication requires the capability of designing and developing both the optical and the quantum communication payloads on the satellite side, as well as the competence to realize dedicated telescopes coupled to the quantum hardware on ground.

Thanks to the contribution of the lead Italian scientists in the context of space quantum communication and of one of the most recognized professional telescopes producer in the world, at ThinkQuantum we can effectively tackle the complexity of this new space technology.

Quantum Random Number Generation (QRNG)

Random numbers are an invaluable resource for many different applications, such as simulations, gaming, and data security.

In particular, they are a fundamental building block for both classical and quantum cryptography: their security relies on the unpredictability of the random numbers, and the privacy of the encrypted data is compromised if the random number generators are flawed.

The majority of random number generators (RNG) used today are based on deterministic algorithms, meaning that no matter how well the generator is designed, it will always be predictable.

In the last years, the flaws in these RNG have been exploited by attackers to realize important security breaches of different cryptographic systems.
On the other hand, Quantum Random Number Generators (QRNG) exploit the intrinsic randomness of Quantum Mechanics to deliver secure and private random numbers. The processes at the heart of the QRNG are inherently non-deterministic, and they cannot be predicted, even if the full status of the system is known with absolute precision.

Our technology combines high-security standards with state-of-the-art performances at low cost, providing an optimal solution for a broad set of applications requiring the highest levels of security.
