 uantum technology applications demand properties that are impossible to re
 alize within a single physical platform. Hybrid quantum systems offer a po
 werful solution: by combining complementary components\, their strengths c
 an be pooled and their weaknesses mutually compensated. In this talk\, I w
 ill explore hybrid platforms connecting flying qubits (photons) and statio
 nary qubits (spins)\, focusing on spin ensembles coupled to microwave phot
 ons in superconducting circuits.Starting from the first demonstration of s
 trong coupling between nitrogen-vacancy (NV) spin ensembles in diamond and
  superconducting microwave cavities\, I will show how this platform enable
 s rich quantum optical phenomena — from protecting collective spin state
 s against decoherence\, to spectral hole burning for coherence engineering
  in microwave photonics\, to understanding the fundamental spin lifetime l
 imits set by phononic vacuum modes. Collective coupling also gives rise to
  superradiance\, and I will briefly discuss our journey from the first obs
 ervation of superradiant emission in NV ensembles to the recent discovery 
 of self-induced superradiant masing\, driven by many-body spin-spin intera
 ctions.As an outlook\, I will present a radical new platform: atomic impur
 ities embedded in noble gas quantum solids grown directly on superconducti
 ng cavities. Recent experiments demonstrate strong coupling of sodium atom
 s in a neon crystal to a superconducting circuit\, opening a path toward c
 oherent coupling of a single spin defect to a superconducting resonator. 
 Biography:Jörg Schmiedmayer is a Professor of Experimental Physics at the
  Faculty of Physics at the TU-Wien\, Vienna\, Austria. He was a founding m
 ember of the Vienna Centre for Quantum Science and Technology. Schmiedmaye
 r is one of the pioneers of matter wave interferometry and quantum simulat
 ion science. His invention of micro traps for neutral atoms and the AtomCh
 ip triggered a new field of research\, micro-manipulation of atoms\, ions 
 and molecules. His research on non-equilibrium evolution and relaxation st
 arted a new direction in many body quantum science and continues to inspir
 e new research directions worldwide. His detailed analysis of correlations
  in many body quantum systems started a new field in quantum information s
 cience: quantum simulation of quantum field theories and emerging quantum 
 simulators which have to be contrasted with simple building the hamiltonia
 n directly in the lab as in Hubbard models. He is a recipient of several p
 restigious grants and awards\, including the Wittgenstein Prize. He is ful
 l member of the Austrian Academy of Sciences. \n\nhttps://indico-tdli.sjt
