Pixel Photonics, a Quantum technology spin-off from WWU Münster, raised 1.45 million euros in seed-funding from HTGF, Quantonation and business angels

March 29, 2022

Münster, 29th of March 2022 Pixel Photonics, a start-up out of the physics department of WWU Münster founded in 2020, has raised 1.45 million euros in a seed-round from German VC fund High-Tech Gründerfonds (HTGF), French quantum-focused VC fund Quantonation as well as the photonic industry veteran Dr. Hendrik Sabert.

Pixel Photonics develops highly scalable integrated-optical single-photon detectors that enable scaling of solutions in quantum computing, QKD and imaging among others. The underlying waveguide based SNSPD approach could be used to boost performance of photonic quantum computing, quantum key distribution, microscopy, or other sensing applications, that require highly efficient detection of light at single photon level. During the incorporation, Pixel Photonics was supported by the REACH EUREGIO Start-up Center in Münster as well as an EXIST research transfer grant.

The seed-funding provides us with much needed capital to expand our team and to shorten our time-to-market in the rapidly evolving market for single photon detectors. With the financial support and commitment of our investors we can leverage national and international research programs in quantum technologies effectively. We are proud as a team, that such high-profile venture funds as Quantonation and HTGF are sharing our vision.

Nicolai Walter, CEO and co-founder Pixel Photonics GmbH

Quantonation and HTGF have co-led the seed round together with serial founder, former venture capital manager and photonics industry veteran Dr. Hendrik Sabert. With this funding Pixel Photonics will further expand its international team in Germany and its facilities at the Center for Nanotechnology (CeNTech) in Münster and accelerate the commercialization of its products. In addition, Pixel Photonics will benefit from Quantonation’s outstanding international network within the quantum technology community as well as from access to HTGF’s extensive industrial technologies portfolio.

Pixel Photonic’s unique technological approach to single photon detection combines scalability with high detection efficiency at very high speed. This makes new applications feasible and helps to scale the number of channels in quantum computing or data rates in quantum cryptography without increasing technical complexity. The team of physicists turned entrepreneurs, which emerged from the groups of Prof. Pernice an Prof. Schuck, persuaded us by its vision and expertise.

The idea behind Pixel’s detector design was born years ago out of research of Prof. Wolfram Pernice and Prof. Carsten Schuck. Researchers were looking for single photon detectors with multiple channels in combination with additional functionality provided by integrated optics. This resulted in the first sale of a detector with four channels for research purposes early this year. Systems with 32 or more channels will be introduced in the near future.

In addition to venture capital funding, Pixel Photonics and the physics department of the Westfälische Wilhelms-Universität (WWU) Münster have been awarded 2.6 million euros in research funding from the Federal Ministry of Education­ and Research (BMBF) to use quantum physics to improve data security. The so-called QSAMIS project, which is funded by BMBF’s “Enabling Start-up” grant for quantum technologies and photonics, aims to develop the first gigabit Quantum key distribution (QKD) system to enable quantum-secure communication for broadband networks.

Deep-tech start-ups built on outstanding academic research are one of the focus areas for investments of HTGF. Pixel Photonics’ single photon detectors offer promising applications in the quantum technologies market and enable innovation in further industrial and biomedical applications. Additionally, we are excited about our third investment with our colleagues from Quantonation.
