The tourism minister send a strong message on Thursday night to his FNM Opponent Pakesia Parker, “You never get a lickin’ til you come to Bimini”. He says “this time we aint taking nobody for fun, this time we are serious here, to continue the path of growth” and promised to score big for the PLP come May 10th. The PLP’s gold team rolled into town, along with a slew of promises to expand the airport. Wilchcombe says flights direct from New York and Mexico were ready to come into Bimini, along with shops and restaurants for Biminites that would promote the sale of indigenous items.He went on to warn constituents not to give the FNM a chance, as Bimini could not afford to stop in its path of growth.center_img Facebook Twitter Google+LinkedInPinterestWhatsApp #MagneticMediaNewslast_img read more

Quaders heart working fine without artificial support

File PhotoThe Intra-Aortic Balloon Pump (IABP) machine, which was set up in the heart of ailing road transport minister and bridges minister Obaidul Quader, was removed on Thursday morning as his condition is improving gradually, reports news agency UNB.“His heart is working fine without any artificial support,” Bangabandhu Sheikh Mujib Medical University (BSMMU) director Abu Naser Rizvi, who was accompanying the minister, informed media referring to the statement of cardiologist Philip Koh of Mount Elizabeth Hospital at noon.The kidneys of the minister have been functioning better than before and the quantity of sedative has also been reduced, said Rizvi.”The minister is also responding to doctors’ call,” he added.He further said many of his infections are under control.His wife Isratunnesa Quader and Md Mustafizur Rahman, Bangladesh High Commissioner in Singapore were also present at the briefing.Quader, also general secretary to ruling Bangladesh Awami League (AL), was flown to Singapore on Monday for better treatment as per advice of renowned Indian cardiologist Devi Shetty.The minister was admitted to the BSMMU on Sunday morning following breathing complications. Later, physicians conducted an angiogram and found three blockages in his coronary arteries.last_img read more

Worldwide quantum web may be possible with help from graphs

first_img Explore further “A worldwide quantum network may appear quite similar to the internet—a huge number of devices connected in a way that allows the exchange of information between any of them,” coauthor Michael Epping, a physicist at the University of Waterloo in Canada, told Phys.org. “But the crucial difference is that the laws of quantum theory will be dominant for the description of that information. For example, the state of the fundamental information carrier can be a superposition of the basis states 0 and 1. By now, several advantages in comparison to classical information are known, such as prime number factorization and secret communication. However, the biggest benefit of quantum networks might well be discovered by future research in the rapidly developing field of quantum information theory.”Quantum networks involve sending entangled particles across long distances, which is challenging because particle loss and decoherence tend to scale exponentially with the distance.In their study published in the New Journal of Physics, Epping and coauthors Hermann Kampermann and Dagmar Bruß at the Heinrich Heine University of Düsseldorf in Germany have shown that describing physical quantum networks as abstract mathematical graphs offers a way to optimize the architecture of quantum networks and achieve entanglement across the longest possible distances. “A network is a physical system,” Epping explained. “Examples of a network are the internet and labs at different buildings connected by optical fibers. These networks may be described by mathematical graphs at an abstract level, where the network structure—which consists of nodes that exchange quantum information via links—is represented graphically by vertices connected by edges. An important task for quantum networks is to distribute entangled states amongst the nodes, which are used as a resource for various information protocols afterwards. In our approach, the graph description of the network, which might come to your mind quite naturally, is related to the distributed quantum state.”In the language of graphs, this distributed quantum state becomes a quantum graph state. The main advantage of the graph state description is that it allows researchers to compare different quantum networks that produce the same quantum state, and to see which network is better at distributing entanglement across large distances.Quantum networks differ mainly in how they use quantum repeaters—devices that offer a way to distribute entanglement across large distances by subdividing the long-distance transmission channels into shorter channels. Here, the researchers produced an entangled graph state for a quantum network by initially defining vertices with both nodes and quantum repeaters. Then they described how measurements at the repeater stations modify this graph state. Due to these modifications, the vertices associated with quantum repeaters are removed so that only the network nodes serve as vertices in the final quantum state, while the connecting quantum repeater lines become edges.In the final graph state, the weights of the edges correspond to the number of quantum repeaters and how far apart they are. Consequently, by changing the weights of the edges, the new approach can optimize a given performance metric, such as security or speed. In other words, the method can determine the best way to use quantum repeaters to achieve long-distance entanglement for large-scale quantum networks.In the future, the researchers plan to investigate the demands for practical implementation. They also want to extend these results to a newer research field called “quantum network coding” by generalizing the quantum repeater concept to quantum routers, which can make quantum networks more secure against macroscopic errors.

DOI: 10.1088/1367-2630/18/5/053036 (Phys.org)—One of the most ambitious endeavors in quantum physics right now is to build a large-scale quantum network that could one day span the entire globe. In a new study, physicists have shown that describing quantum networks in a new way—as mathematical graphs—can help increase the distance that quantum information can be transmitted. Compared to classical networks, quantum networks have potential advantages such as better security and being faster under certain circumstances. Physicists have shown that, by describing a quantum network as a mathematical graph, they can determine the best way to use quantum repeaters to achieve long-distance entanglement.
