Quantum Logic Gate Created Using Excitons 146
Roland Piquepaille writes "In this article, PhysicsWeb reports that researchers in the U.S. "have taken another important step towards making a quantum computer. [They] have created a logic gate using two electron-hole pairs -- also known as "excitons" -- in a quantum dot." According to Wikipedia, "an exciton is a combination of an electron and a hole in a semiconductor or insulator in an excited state These physicists from the University of Michigan and other labs made a quantum dot by using a thin gallium arsenide layer stuck between two aluminium gallium arsenide barriers. And electrons trapped in the middle layer were excited by light to create a quantum logical gate with four states. The group says this could be useful "in other approaches to quantum computing based on the optical control of electron-spin qubits in quantum dots.." This summary contains more details."

and thought "I'm sure I've seen that on a Powerpoint presentation somewhere". This is clearly uber-smart stuff by uber-smart people, but they are beginning to sound like clueless PHBs dressing things up in techno-babble.
Maybe this is the fundamental essence of quantum computers, something maybe smart or idiotic depending on the reader, the actual quality of work is only resolved when viewed by multiple individuals.
I hearby copyright the phrase Quantum-Powerpoint, and the resolution process of determining presentation value which I shall call "De-spinning Qubits"
