Get closer with Quantum Zoom:
Particle Sensor with Real-time Shape Recognition

The Q.ANT Particle Sensor reveals what’s previously been hidden:
the shape and structure of the smallest particles. And all in real-time.

Better quality at higher efficiency? The solution lies in the smallest particles.

Quantum-based particle sensors enable more sustainable processes, more energy-efficient applications and industry products of the highest quality. Welcome to the future of particle measurement!

This converts the light in the superposition state back into linear light waves.

Measurement output

Data from the light measurement is fed from this output to software that uses it to generate information about the items measured.

Light in superposition state

The light in the superposition state is beamed to the measurement cell.


This focuses the laser beam and converts the incoming linear light waves into light in a superposition state.

Linear light waves

Linear light waves strike the lens.

Laser driver

This generates the laser beam.

Measurement cell

In this cell. the particles flow in gas, liquids or as powder through a translucent tube.

The quantum trick

The light in the superposition state "illuminates" a particle simultaneously in several dimensions. This allows conclusions to be made almost immediately about the speed, size, position and shape of the particle being examined.

Optical fiber

This guides the laser beam.

Enlightning with the Quantum Trick

Q.ANT Particle Sensors work through deliberately generated quantum effects in excited light. When light in a superposition state meets a particle, it is illuminated in multiple dimensions simultaneously. This allows many pieces of information to be gathered in one real-time measurement, such as the particle’s speed, size, position, and shape. We call this the Quantum Trick.

With the help of the Q.ANT particle sensor, we are opening a whole new chapter in our Bionic Learning Network.
