GeQD is part of the QuantumBW network and actively supports the development of Baden-Württemberg into a central player in the global quantum industry.

GeQD pitches at Expo 2026 of Startup Autobahn by Plug & Play

As part of an exclusive session at the Expo 2026 of Startup Autobahn by Plug & Play, GeQD was invited to present as one of 5 startups at Impact Hub Stuttgart. Hosted and attended by Plug & Play founder Saeed Amidi, Maurice showed why SWIR sensing will…

Victory! GeQD and IHT win the ETI-Cup 2026

Victory! The GeQD team together with the IHT (Institute of Semiconductor Technology) team won the prestigious ETI-Cup 2026, bringing the trophy to the Institute of Semiconductor Technology at the University of Stuttgart for the first time. Resilience,…

GeQD featured on Elektroniknet.de: Quantum detectors also for medical technology

GeQD is featured on Elektroniknet.de: The article "Stuttgart spin-off: Quantum detectors also for medical technology" introduces our germanium-on-silicon photodetector, which according to the report already operates at -10 to -20 °C – significantly less…

GeQD Q2 Recap – We got started

We have moved into our new office, set up dedicated laboratory stations and entered the first phase of building germanium-based single-photon detectors for scalable quantum technologies, LiDAR and advanced imaging. For us, this quarter was about getting…

GeQD at the Stuttgart Science Festival

On Friday, 26 June, GeQD was one of the invited start-ups at the opening event of the Stuttgart Science Festival at the city hall. The event impressively highlighted how important the interface between science, technology and commercialisation is. We…

GeQD at the Applied Deep Tech Fest by NXTGN

On Wednesday, 24 June, Maurice Wanitzek and Maximilian Scheu were on-site at the Applied Deep Tech Fest hosted by NXTGN at Arena 2036 in Stuttgart, presenting the advantages of germanium-based Single-Photon Avalanche Diodes (Ge-SPADs). The focus was on direct…

Paris in the spotlight of quantum technologies: GeQD at the European Quantum PhD Days and Viva Tech

Maurice Wanitzek spent this week in Paris in dialogue with quantum researchers from across Europe. At the European Quantum PhD Days, PhD candidates working on quantum communication, quantum sensing and quantum computing came together to discuss current…

Press release from the University of Stuttgart on GeQD:

Highly sensitive light sensors for quantum communication, medical technology and autonomous driving: Researchers at the IHT of the University of Stuttgart have developed a germanium-based photodetector that is more cost-efficient and flexible than…

Quantum-LiDAR: What happens when quantum physics meets 3D sensing?

Classical LiDAR measures distance via light travel times: a laser emits short pulses, reflected light returns, and distance is calculated from the round-trip time. Quantum-LiDAR extends this approach by using quantum-mechanical properties of light — such as…

Will the quantum internet become a mass market, or specialised infrastructure?

When people talk about the quantum internet, a familiar image emerges quickly: at some point a "quantum router" in every household, as a logical continuation of today's internet. That is plausible. Looking back at the last century, the first computers were…

Necessity vs. Sufficiency – What matters when bringing quantum technologies to market

Conversations about single-photon detection quickly turn to record numbers: maximum detection efficiency, minimum dark count rate, lowest possible jitter. In research, this logic makes sense — anyone working at the limit of what is measurable wants to…

Why Single-Photon Detection Matters

Single-photon detection may sound like a niche topic from the physics lab. In reality, it describes a capability that is critical for many modern optical technologies: detecting individual particles of light — the smallest measurable unit of light. While…

World Quantum Day: Why 4.14 Is More Than Just a Number

Because 4.14 points to one of the most important constants in physics: Planck's constant. It captures the idea that energy does not flow continuously, but in tiny packets — quanta. For light, that means it comes as individual photons. This insight is the…
