Lidia Lozano Martín (ICCUB) Is it possible to develop an efficient solid-state emitter of single and entangled photons suitable for space to ground communications among other quantum applications? Present single-photon and entangled-photons emitters exhibit important challenges, limiting their use in quantum applications like secure communication based on quantum key distribution (QKD), quantum metrology and sensing.…
Welcome to the Spanish Network on Quantum Information (RITCE)
Quantum Information
Quantum information is the new language of Quantum Science, describing and explaining the structure of complex quantum systems, entanglement, and their potential for storing, encoding and processing information.
Quantum Technologies
Quantum mechanical systems can be used to enhance common tasks, such as metrology and sensing, as well as to build new forms of computation & cryptography that cannot be beaten by classical devices.
Quantum Simulation
Quantum simulation is the experimental control of atoms, molecules or even solid state devices, to simulate or solve interesting problems from Condensed Matter or Theoretical Physics.
The Spanish Network on Quantum Information (RITCE), promotes research in all of these fields, helping the establishment of collaborations inside the network and with international groups, and promoting the training of new scientists in these topics.

- Online seminar #18: Topological phases and entanglement at the boundary of an expanding universe
Carlos Fulgado (IFT) One of the most striking phenomena within the realm of Quantum Field Theory in Curved Spacetimes is the creation of particles as a consequence of the expansion of the universe. We study this effect for the case of Dirac fermions and propose a cold-atom gravitational analogue to implement this effect in controlled…
- Online seminar #17: The device-independent scenario: quantum information processing based on Bell theorem
Antonio Acín (ICFO) Bell’s theorem proves the existence of quantum correlations, often known as Bell nonlocal, that cannot be described by classical theories, in which measurement outcomes are predetermined. In recent years, Bell nonlocal correlations have also acquired the status of information resource, as they are crucial for the construction of quantum information protocols in…
