Quantum Bug: Qubit might spontaneously decay in seconds

Article Abstract:

Physicists should overcome a fundamental obstacle before quantum computers can become a practical reality, causing decoherence, that is, the loss of the very quantum properties, which computers would rely on. A device based on superconducting quantum bits (qubits) predicts that new source of decoherence would degrade the quibits after just a few seconds.

Chaos in the crater

Article Abstract:

Vredefort is the oldest and largest impact remnant on the planet, created about two billion years ago with a 10-kilometer-wide asteroid slammed into the earth. Intense, random magnetism in the Vredefort Crater occurs due to a strong and chaotic magnetic field generated by currents flowing in the ionized gases produced at the height of the collision.

The discovery machine

Article Abstract:

The article discusses the Large Hadron Collider (LHC), the world's most powerful microscope that can be used for all possible physics experiment. The machine is capable of physics problems of the shortest distances and highest energies.
