Southern CTA site confirmed to be in Chile

On 19 December 2018, the Cherenkov Telescope Array Observatory (CTAO) and the European Southern Observatory (ESO) signed the final agreements needed for CTA’s southern hemisphere array to be hosted near ESO’s Paranal Observatory in Chile. With these agreements in place, the CTAO will be able to begin construction on the southern site. The hosting agreement with the Instituto de Astrofísica de Canarias (IAC) is already in place to host CTA’s northern hemisphere array at the Observatorio del Roque de los Muchachos in La Palma, Spain.

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.
