Quantum Information
The group is composed by
Rosario Fazio (Scuola Normale Superiore), Vittorio Giovannetti (Scuola Normale Superiore) and Simone Montangero (Scuola Normale Superiore).
The main research lines of the group are:
Entanglement in Many-Body systems
-thermodynamics of entanglement: phase transitions versus quantum coherence.
-"computing" the entanglement of a Many-Body system: refining Density Matrix
- Dynamics of quantum phase transitions
Quantum computation and quantum chaos
- the "scaling" of efficiency of quantum algorithms
- stability of quantum algorithms in presence of errors
- quantum simulation of classically chaotic systems
Quantum communication
- efficiency trade-off: the channel capacity problem
- constrained channels: how to transfer classical/quantum messages if your syst\em allows only for limited control.
- additivity problem
- exploiting quantum communication as a resource for computation
- wiring sites of high quality control (e.g. quantum computer) with solid state devices
Quantum estimation theory: efficiency in measurament
-resolution/resources trade-off
-measuring entanglement in real systems: separability criteria
- entanglement witness.
Solid state quantum information with superconducting nonocircuits
-quantum control theory
-development of a hybrid thecnology: quantum computation meets nanotechnology.
