Welcome to this LT30 satellite, Low-Temperature Quantum Detectors: from fundamentals to applications, hosted in Helsinki, Finland! This event is co-organized by InstituteQ, Finland’s national quantum institute, and SUPERQMAP COST Action 21144.

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.

Conference topics

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

     

      • novel read-out methods and devices for quantum computers

      • 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
