Photonic Computing: Paving the way to quantum computing

Unlock the potential of photonic chips and processors and shape the future of information technology

The Power of Quantum Computing

The world of information technology is on the brink of a transformative leap forward. Quantum computing has become a reality, revolutionizing the way of processing and analyzing data. Quantum computing isn’t just about faster calculations; it’s about solving problems that were once considered unsolvable. It holds the potential to tackle some of the most pressing challenges of our time. With our photonic chips and photonic processors, we are paving the way to photonic quantum computing. The future is quantum, starting here.

The Wide Range of Applications

Lithium Niobate - The Optimal Material Choice for Photonic Integrated Circuits

Q.ANT relies on its own technology platform for photonic chips and photonic integrated circuits – PICs. The central components of the chips are optical waveguides and various building blocks, which enable the control of light and in a highly integrated form. In this system, very thin layers of lithium niobate are applied on silicon and then structured into optical waveguides. We believe that lithium niobate – LNOI – is the key to future photonic computing.

PICs based on LNOI  show several main advantages:

Unlocking the Power of Photonic Computing for HPC

High-performance computing is undergoing a huge shift. Photonic and quantum computing enters as the game-changer that holds the potential to reshape the way we process data and analyze and solve complex problems. Photonic computing transcends the limitations of classical computing systems, opening up new horizons for discovery and innovation in various fields such as science, engineering, artificial intelligence, finance, and healthcare. 

Q.ANT serves as the one-stop-shop from chips to applications with several main advantages:  


These guide tiny particles of light (photons) through conductive paths.

Laser source

This beams classical light waves into the waveguide.


The photons are manipulated through the building blocks on the chip, as i.e. modulators or resonators. 


This occurs on the waveguide at the narrow points, also called beam splitters. It means that photons can pass into the other waveguide.


This is used to read out the information that the photons carry. 

Special algorithms

These control the interaction of photons and calculate previously unsolvable tasks.

The Photonic Chip

At the heart of photonic processors are photonic chips that perform calculations. In this process, photons deliver huge computing power.
