"Previous research has only succeeded in creating some building blocks for a quantum computer by using atoms suspended in a vacuum. However it has not been possible to make enough for a whole computer as scientists can only hold a limited number of atoms in place for a short period of time. Using atoms trapped in a silicon crystal, the research ( Read more... )

"The prototype of the quantum cryptography chip is already available, and the corresponding fiber-optic network for absolutely safe, chip-based data transfer will be presented in October 2008 at Siemens IT Solutions and Services in Vienna."

Cryptographic communications, you've come a long way, baby.

“It tells us that we really can't assume that measurements create reality, because it is possible to erase the effects of a measurement and start again.”

The quantum state can be intentionally manipulated - pretty neat.

World's shortest single photon pulse created.

An optical CNOT gate and secure photon identity.

A couple of nice articles about photons as information carriers, and a new idea for memory using quantum dots.

If they can just increase storage times . . .

Quantum dots just keep getting cooler.
