The new discovery from Toshiba Research Europe and the University of Cambridge can be used in a number of different ways
Researchers from Toshiba Research Europe Ltd. and the University of Cambridge have announced a quantum device that can create entangled light.
The process starts with a silicon-based device that uses quantum
dots inside a block of indium arsenide. Quantum dots are
essentially nanocrystals small enough to exist in the quantum
confinement regime. When the quantum dot is excited by
a laser pulse, two electrons in
the indium arsenide are excited. The energy will then be
converted into two entangled protons that can be split outside the
device.
The technology has many different uses: including quantum computing,
medical imaging, chip production and communications. Quantum
computing, here we come!
"We are going to continue to work with them to make sure they understand the reality of the Internet. A lot of these people don't have Ph.Ds, and they don't have a degree in computer science." -- RIM co-CEO Michael Lazaridis
