qCMOS camera ORCA-Quest enabling 2D photon number resolving and its applications

David Castrillo - 2025 Speaker

Presentation highlights:

  • ORCA-Quest is the world’s first quantitative CMOS camera which realises high resolution, high sensitivity, high frame rate and ultra-low readout noise at the same time.
  • In thanks especially for the superior design and the fabrication technologies for sensors and cameras it achieves 0.3e- rms readout noise which makes the world’s first 2D photon number resolving capability, meaning that it enables precise quantification of photoelectrons.
  • Due to those high-performance features, ORCA-Quest is applied in various applications such as quantum technologies, astronomy, material science and life sciences.
  • In this presentation we introduce 2D photon number resolving capability and some use cases in quantum computing applications.

It’s your first time speaking at ISE – what are you looking forward to in terms of participation?

Yes, it is the first time to attend this promising meeting. And what I look for is not only to attend the meetings, but to meet the people and have good discussions. 

Tell us a bit more about the themes you will be focusing on in your presentation, and your background in the sector

Imaging sensors have played a crucial role in Hamamatsu Photonics from the day 1 of the company. Our strategy was focused during the last 40 years on reducing noise exploring many different technologies. Today we are in a magic moment in which we can see individual photons arriving to the sensor. We broke one barrier and now can explore new applications, like Quantum, that will generate new questions.

What key technology and application trends do you see emerging this year and next for the image sensors sector?

This is difficult to answer, but the evolution never stops. Lower noise, higher speed, good linearity, and acceptable price. The sensors will continue to evolve, and from time to time, a disruptive technology will happen. Which one is next? It is a game to play, we can sometimes win and sometimes lose, but we cannot stop trying.
