Qubits in the pink

Article Abstract:

New developments in the study of the nitrogen-vacancy defect in diamonds, which gives them a characteristic pink colour, are described. These defects can be brought into resonance, by tuning the energy of the spin states of the defects using a magnetic field, exchanging energy and polarization with virtual photons and this combination forms a two-qubit structure for quantum computing.

Old diamond and upper crust

Article Abstract:

The debate on was the earth a blackened landscape of congealed lava, or was it cool enough for oceans to form is still not clear. The discovery of diamonds in zircons, the earliest known remnants of Earth's crustal rocks that occur in conglomerates at Jack Hills in Australia has added a new flair to the debate.

Superconductivity in diamond

Article Abstract:

Boron-doped diamond synthesized at high temperature and pressure shows property of superconductivity. The discovery of superconductivity in diamond-structured carbon also reveals that Si and Ge may exhibit superconductivity under appropriate conditions.
