Carbon nanotubes open new path toward quantum information technologies

In optical communication, critical information ranging from a credit card number to national security data is transmitted in streams of laser pulses. However, the information transmitted in this manner can be stolen by splitting out a few photons (the quantum of light) of the laser pulse. This type of eavesdropping could be prevented by encoding bits...

Scientists witness and measure displacement of atoms

Using state of the art technology, researchers at the Monash Centre for Electron Microscopy (MCEM) have developed new methods which allow tiny displacements of atoms to be witnessed and measured. The research, published in the latest edition of prestigious journal ("Direct mapping of Li-enabled octahedral...

Semiconductor quantum dots as ideal single-photon source

With the help of a semiconductor quantum dot, physicists at the University of Basel have developed a new type of light source that emits single photons. For the first time, the researchers have managed to create a stream of identical photons. They have reported their findings in the scientific journal ("Transform-limited single photons from a single...
