Welcome to this LT30 satellite conference, Low-Temperature Quantum Detectors: From fundamentals to applications, hosted in Helsinki, Finland! This event is organized by InstituteQ, Finland’s national quantum institute.
Recent developments in low-temperature detectors incorporate genuine quantum features, promising to reach unprecedented levels of measurement precision. On a fundamental level, these highly sensitive detectors will give us a glimpse into the world of quantum/thermal fluctuations and the effect of measurement backaction, and will advance the utilization of quantum resources and feedback. They will create a pathway to scientific breakthroughs: novel phenomena in condensed-matter physics, enhanced spectroscopical characterization, observation of new particles, and understanding the interaction between gravity and quantum-mechanical objects.
When: August 3-6, 2025
Where: Clarion Hotel, Tyynenmerenkatu 2, 00220 Helsinki
Registration: Register at the LTQD2025 event webpage

The LTQD2025 conference will be hosted at the Clarion Hotel in the Jätkäsaari district of Helsinki. The hotel boasts impressive amenities, including a heated rooftop pool and terrace, sauna, and a modern gym and workout facility.
Located at the top of one of the hotel’s towers is the Skyroom bar, showing spectacular views of Helsinki. For event attendees arriving on August 3, there will be a welcoming drinks session at the Skyroom.
The Clarion Hotel has easy access to many of Helsinki’s great attractions. Fancy a seaside sauna? Löyly Helsinki is just a short tram ride away, and it offers a modern twist on the traditional Finnish sauna experience, as well as a full restaurant and bar. Sightseers can easily access Finland’s landmark cathedral, Tuomiokirkko, situated in the heart of Helsinki.
