Sara Felloni



My research is in quantum information processing, with a focus on the study of decoherence, inaccuracy and errors in quantum computation and communication. I am especially interested in:
  • Quantum noise models
  • Quantum computations in experimentally realistic conditions
  • Quantum cryptography and communication protocols in experimentally realistic conditions and against quantum adversaries
  • Quantum information representations
  • Quantum channels capacities
