Maintaining Entanglement for an Hour

Maintaining quantum states for any length of time is one of the big challenges in quantum computing. So this news about maintaining entanglement for an hour is encouraging. (Image from the article.)

Suppressing decoherence

Some progress towards suppressing decoherence, a major stumbling block towards physical implementations of quantum computers.

Overcoming Decoherence

Here's a good article in this month's Scientific American: How Noise Can Help Quantum Entanglement.

Decoherence is the largest obstacle in the physical implementation of quantum computers, so steps towards overcoming the current problems with it are important.
