By Pascal Deladurantaye – Director of Products and Strategic Marketing Quantum computing threatens traditional encryption, driving the need for quantum-secure solutions like Continuous-Variable Quantum Key Distribution (CV-QKD). This article explores the challenges and success factors for large-scale CV-QKD deployment and ...
In this blog summarizes indie Photonics’ optical components and subsystems that empower next-generation quantum technologies, specifically quantum computing and Quantum Key Distribution (QKD). indie’s portfolio includes ultra-low-phase-noise lasers, high-performance optical filters, and advanced photonic integration platforms that together enable scalable, ...
Quantum Key Distribution (QKD) is a cryptographic primitive that lets two distant parties, conventionally called Alice and Bob, generate a shared string of random bits that only they know. Unlike public key algorithms whose security rests on unproven mathematical assumptions, QKD relies on ...
Narrow-Linewidth DFB Laser Diode with Unique Modulation ResponseEdge-emitting distributed feedback laser (DFB) diodes are small-sized laser sources that can be produced in high volumes at a low cost. They are widely deployed in telecommunication systems and have proven to be ...
What Does “Discrete Variables” Refer To? Discrete variables (DV) refers to quantities that can be counted based on specific and indivisible observations, in opposition to continuous variables (CV) that can take any value with a range. In the context of QKD, ...
Background Quantum science is a century-old field of study, but recent technological advancements led to the enablement of new techniques to tap into the endless potential of quantum mechanical properties expressed at the single particle level. One can now exploit ...
Overcoming QKD Engineering Challenges Quantum Key Distribution (QKD) in quantum communications is a secure communication method that enables two parties to produce shared secret keys used afterward to encrypt and decrypt messages. Based on the principles of quantum mechanics, the ...
Fiber Bragg gratings can be used to obtain different wavelength reflectivity profiles that depend on the refractive index pattern that is inscribed in the fiber. By relying on proven in-house design and simulation tools and state-of-the-art grating inscription methods, unique ultra-narrowband fiber-based ...
