Diamonds are forever — or, at least, the effects of this diamond on quantum computing may be. A team that includes scientists from USC has built a quantum computer in a diamond, the first of its kind to include protection against “decoherence” — noise that prevents the computer from functioning properly.

The most extensive quantum computation in history took just 270 milliseconds, say quantum physicists.

New Hybrid Technology Could Bring ‘Quantum Information Systems’
The merging of two technologies under development — plasmonics and nanophotonics — is promising the emergence of new “quantum information systems” far more powerful than today’s computers.

Computer scientists have built a superconducting number cruncher with a Von Neumann architecture that paves the way for a new era of quantum computation(via First Quantum Computer With Quantum CPU And Separate Quantum RAM - Technology Review)
This could be a first stumbling step from primitive quantum computer technology towards a real world computer application.
Using what looks like an incredibly complicated setup, scientists have not just figured out how to transport information using the quantum highway; they have actually made it happen. Story: PCWorld via @mmartocciaQuantum Teleportation Is a Reality
In a step toward a generation of ultrafast computers, physicists have used bursts of radio waves to briefly create 10 billion quantum-entangled pairs of subatomic particles in silicon. The research offers a glimpse of a future computing world in which individual atomic nuclei store and retrieve data and single electrons shuttle it back and forth.
An Australian-led team of scientists have taken a big step forward in the race to develop a quantum computer.
In an article published in Nature, the researchers say they have cracked the second part of this puzzle, by creating a device that measures the spin state of a single electron in a single phosphorus atom inside a block of silicon.
Scientists develop new ‘photonic’ chip that could make quantum computers a reality
The photonic chip, built by scientists from Bristol’s Centre for Quantum Photonics, uses light rather than electricity to pass information.
Machine Learning with Quantum Algorithms
“Many Google services we offer depend on sophisticated artificial intelligence technologies such as machine learning or pattern recognition. If one takes a closer look at such capabilities one realizes that they often require the solution of what mathematicians call hard combinatorial optimization problems. It turns out that solving the hardest of such problems requires server farms so large that they can never be built.
A new type of machine, a so-called quantum computer, can help here.”
Scientists Test First Universal Programmable Quantum Computer
Physicists have been taking baby steps toward creating a full-fledged quantum computer faster and more powerful than any computer in existence, by making quantum processors capable of performing individual tasks. Now a group at the National Institute of Standards and Technology (NIST) has developed the world’s first universal programmable quantum computer that can run any program that’s possible under the rules of quantum mechanics.
