Optalysys announces unifying hardware acceleration for all FHE schemes

Fully homomorphic encryption is an immensely valuable tool for collaborating on the most sensitive data. Optalysys are developing hardware accelerators to overcome the technical limitations of FHE and enable the full potential of quantum-secure private computing…

Max, min, & sort functions using Programmable Bootstrapping in Concrete FHE

In this article, we show how to compute the maximum and minimum of an encrypted array of data without decrypting it, using Zama’s Concrete implementation of the TFHE programmable bootstrapping. 

Optical accelerator enables Fully Homomorphic Encryption • Scientific Computing World

Optalysys has announced that its E series of optical processing technologies enable Fully Homomorphic Encryption (FHE) by significantly reducing the time taken to perform Fourier Transform functions.

Optical Accelerator Makes Fully Homomorphic Encryption a Commercial Reality • Opli

The list of things we want to keep secret is nearly endless, yet how much attention do we pay to this process? After all, big corporations or governments are handling it for us on secure systems, so shouldn’t our data be fully protected?

After 2 days of intensive and competitive pitching sessions, Optalysys has been selected from a pool of over 300 candidates who presented their business at the online pitching sessions.


Fully Homomorphic Encryption (FHE) allows computations to be performed on encrypted data.

But FHE is very slow, making it unusable for most applications. The solution is acceleration via dedicated hardware designed to accelerate the most intensive operation. Optalysys’ Echip technology can provide an order-of-magnitude acceleration in homomorphic calculations.


Optical processors light the path to warp factor computing

Computing at the speed of light has been a long time coming, but a new generation of optical processors promise to be faster – and cooler – than electronic incumbents.


The Dawn of Energy Efficient Computing: Optically Accelerating the Fast Fourier Transform Core

By uniquely combining the high speed modulation of silicon photonics, with the parallel processing of free space optics, Optalysys is developing a novel chiplet-based technology to provide new levels of performance and efficiency for Fourier based processes across AI, homomorphic / post quantum encryption and other numerical modelling applications.
