Supersolid simulations

Article Abstract:

A method, which detects supersolids, crystalline substances that can also behave like free-flowing superfluids, by analyzing the quantum interference that occurs between atoms when released from a web of confining laser light, is proposed. The technique offers the advantage of measuring the defining signatures of superfluidity and spatial order directly, and thus can answer long-standing questions on the existence and properties of supersolid matter.

Direct spectroscopic observation of quantum jumps of a single molecule

Article Abstract:

Quantum-mechanical effects in large polyatomic molecules is revealed by single-molecule spectroscopy. The effects provide information on Bohr's idea of quantum leaps between two electronic shells of an excited atom. The spectroscopic method requires single ions trapped in radio-frequency traps, which are then made to react with a driving lasing field. The spectroscopic method uses a system made of terrylene doped on to p-terphenyl crystals.

Optical coherent state discrimination using a closed-loop quantum measurement

Article Abstract:

Various closed-loop quantum measurements, in addition to the theoretical methods are used to show that real-time quantum feedback can be easily used in the place of a delicate quantum measurement for discriminating between the different optical coherent states. The analysis clearly states that the quantum resources, like enlargement and superposition states are quite fungible, as such quantum feedbacks are not available all the time.
