Canonical Form and Separability of PPT States in C2 ⊗ CM ⊗ CN Composite Quantum Systems
Quantum entangled states have become one of the key resources in the rapidly expanding field of quantum information processing and computation [1, 2, 3, 4]. Nevertheless, the study of physical character and mathematical structure of the quantum entanglement is far from being satisfied. One even does not have a general criterion to judge if a quantum (mixed) state is entangled or not. For bipart...

It is probably very hard to develop a new model checker that is faster than UPPAAL for verifying (correct) timed automata. In fact, our tool MCTA does not even try to compete with UPPAAL in this (i. e., UPPAAL’s) arena. Instead, MCTA is geared towards analyzing incorrect specifications of timed automata. It returns (shorter) error traces faster.

As one of the most striking features of quantum phenomena [1], quantum entanglement is playing very important roles in quantum information processing such as quantum computation [2], quantum teleportation [3, 4, 5, 6] (for experimental realization see [7]), dense coding [8] and quantum cryptographic schemes [9, 10, 11]. The separability of pure states for bipartite systems is quite well underst...
متن کامل1 2 C or Not 2 C ?
Political attention has increasingly focused on limiting warming to 2°C. However, there is no consensus on both questions “Is the 2°C target achievable?” and “What should be done with this target that becomes increasingly difficult to achieve?”. This paper aims at disentangling the points of deep uncertainty underlying this absence on consensus. It first gives simple ha ls hs -0 07 50 70 4, v e...
متن کاملC-2/c-3 annulation and C-2 alkylation of indoles with 2-alkoxycyclopropanoate esters.
The annulation reaction between various indoles and 2-alkoxycyclopropanoate esters is reported. Both high efficiency and complete stereochemical control were observed in some cases with this annulation process. A single stereocenter on the cyclopropane controls the diastereoselective formation of up to four new stereocenters. A different reaction course was observed with 3-substituted indole su...
