True vision of a quantum state
Article Abstract:
The most basic quantity of quantum mechanics where particles behave like waves of light and matter behaves as waves is the quantum state which encodes the information about a system. The quantum state can be represented as a Wigner function which is the quantum-mechanical equivalent of the phase space distribution function spanned by position and momentum. The Wigner function was measured which results to negative values in the two-slit experiment where helium atoms passed through a double slit.

Engineering decoherence
Article Abstract:
Myatt and colleagues have induced decoherence by coupling a single ion in a Paul trap to a reservoir. They have engineered three different reservoirs enabling the confirmation of the rate of decoherence scales with the size of the superposition. The work has important implications for the development of quantum computers, as preventing decoherence is critical to their successful operation.
