Welcome to this LT30 satellite, 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 devices 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.

The topics of the conference comprise (but are not limited to) the following:

• ultrasensitive and fast thermometry, bolometry, and calorimetry
• microwave single-photon detectors: applications in axion detection and spin measurements
• new materials (high-kinetic inductance, granular superconductors, topological, graphene, other 2D materials)
• algorithms for sensing, including machine learning
• detectors for particle physics and astronomy
• fundamental limits on sensitivity and quantum metrology
• enabling devices: parametric amplifiers, low-temperature electronics
• gravitational measurements
• entanglement, squeezing, coherence, and active feedback as measurement resources
• unconventional sensors in cQED
• hybrid mechanical/magneto/opto/microwave devices
• superconducting qubits as sensors of electromagnetic fields
