Successful Measurement of the Time Intervals that Enable the Direct Measurement of Electrons in Laser Induced Ionisation

Physicists have worked on the quantum physics description of the tunnelling
effect for 60 years. The group led by Ursula Keller has now for the first time
succeeded in measuring time intervals that enable the direct measurement of
the tunnelling time of electrons in laser-induced ionisation.

Princeton Engineers Develop New Type of Laser for Medical Applications

A Princeton-led team of researchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring and medical diagnostics.

Physicists Taken Significant Step Toward Creation of Quantum Networks

Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms. Though the information remains usable for just milliseconds, even that short lifetime should be enough to allow transmission of data from one quantum repeater to another on an optical network.
