A Quantum Leap in Randomness: Delivering Advanced Solutions for Secure Encryption
April 11, 2025 by Coherent
In our digital world, encryption is the foundation of secure communication. It keeps our online transactions safe, protects sensitive information, and ensures our privacy remains private. However, as technology advances, so do the tools and techniques used by hackers. Cybercriminals are constantly finding new ways to break encryption, including using artificial intelligence, exposing vulnerabilities in systems we rely on daily. This growing threat underscores the need for stronger, more robust encryption methods to safeguard our data.
At the heart of secure encryption lies the concept of randomness. Encryption systems rely on random numbers to generate secure keys, which act as locks to protect sensitive data. But not all randomness is created equal. The quality of randomness, known as entropy, is crucial. High entropy ensures that keys are unpredictable and resistant to attacks. Weak randomness can create patterns that hackers can exploit, voiding the security of the entire system, irrespective of how sophisticated the encryption is.
“Delivering the most advanced randomness solutions for stronger cryptography.”
Randomness itself comes from an entropy source, which captures unpredictability from the physical world. Common entropy sources include phenomena like thermal noise or variations in clock timing. However, these sources alone can’t generate large amounts of random data quickly, so they are typically paired with deterministic random bit generators (DRBGs) to scale the output. While DRBGs stretch the entropy from a source into longer random streams, they do not create true randomness. Since the strength of the security chain is as strong as its weakest link, this makes the quality of the entropy source the ultimate determinant of security, highlighting why high-quality randomness is essential.
One promising solution lies in the quantum behavior of photons, the smallest particles of light. When photons are emitted from a light source, they follow quantum mechanical rules, which are inherently unpredictable. These quantum effects make photon emission an excellent source of true randomness. Unlike traditional methods, quantum randomness is not influenced by external factors, ensuring an exceptionally high level of entropy and security. This capability enables Quantum Random Number Generators (QRNGs) to rise above conventional RNGs by delivering a continuously measurable and verifiable source of entropy.

Our company collaborates with leading experts in advanced randomness technology to create solutions that combine cutting-edge quantum randomness with proven photonics expertise. By leveraging state-of-the-art quantum randomness generation alongside our extensive experience in high-volume, integrated, and miniature photonic solutions, we are redefining what’s possible in encryption and data security.
This partnership addresses critical demands of modern cryptography. It is fast, meeting the accelerating need for higher entropy rates driven by emerging hybrid encryption systems and growing cybersecurity threats. It is measurable, with entropy quality continuously verified in real time through robust hardware checks and physical models. And it is secure by design, leveraging quantum principles to establish a reliable, robust foundation that eliminates vulnerabilities.
“With threats increasing and new hybrid schemes emerging, higher entropy rates are required.”
Today, the security of billions of devices depends on the quality of randomness underlying their encryption. Traditional random number generators, even engineered systems like ring oscillators and avalanche diodes, rely heavily on statistical tests to prove randomness. In contrast, our QRNGs employ in-line physical randomness tests and verification to demonstrate genuine, continuous entropy generation. This makes them especially suited for critical systems, from mobile devices to data centers and beyond.
In today’s world of ever-growing cyber threats such as massively parallelized attacks enabled by artificial intelligence, ensuring the highest quality of randomness is no longer optional—it is a necessity. By integrating best-in-class quantum randomness technology with our photonics expertise, we deliver unparalleled security solutions.
