Quantum photonics with non-Hermitian systems

All physical systems can be roughly divided onto two types. Namely, conservative or Hermitian systems, where the whole system energy is preserved, and non-conservative or non-Hermitian systems, where the energy can irreversibly flow between the system and its surrounding environment.

First realization of controlled quantum teleportation

Controlled quantum teleportation might one day become a building block for future quantum Internet. Its first implementation on quantum bits has recently been reported by scientists from the Joint laboratory of Optics of Palacky University and Institute of Physics of the Czech Academy of Sciences. Using this idea, one can significantly increase the quantum data flow in multi-user networks and even across large distances.
