We just got back from the Bahamas yesterday. Absolutely beautiful once you are at the hotel. Trip to hotel is not the best thing to view. Hotel is amazing and staff is so friendly. The hotel sits right on the beautiful beach front. Our room was clean. It had a great view of pool and ocean. We just ate at the buffet the whole trip Giacomo Bonaventura World Cup Jersey , food was average. Don't think the specialty places are worth the wait in line, though I overheard the food was great at the Steakhouse. The mixed drinks are strong and you get your money's worth. Love that it's all-inclusive.
I really enjoyed my stay here. The food was great, a different theme every night. Bahamian night was our favourite. Rooms were nice although you wont spend much time there, with the pool and swim up bar. I'll be going back again a year from now and I can't wait. Recommend the Riu over any of the others I visited while I was on the island.
Down-side: they only have MGD cans of beer, entertainment is ok, but wish they had dancing, and the peddlers Francesco Acerbi World Cup Jersey , but that is everywhere in the Bahamas. Also fridge in our room did not get very cold. They only stock it every two days as well. This hotel is the best, may not have fancy rooms, but who needs that. I look forward to returning, I miss the place already! It is a much better deal then the hotel next door to the left, which it takes three minutes to walk to and is also worth checking out but not staying at. You will love this place!
They do not offer room service and you are not allowed to bring food out of the restaurants. We would suggest bringing snacks for the times when the restaurants are closed. There is a charge for using the phone in your room (even with a calling card) and they do not have a payphone. We used the payphone at the Atlantis Resort which was just a quick walk next door.
There is a deligrocery a few blocks away near the Blue Marlin, a good restaurant. Water and snacks are cheaper than the hotel. You'll save buying T-shirts and things in Nassau. The Green Turtle by the Marina is a nice change of pace with reasonable drinks and a lengthy happy hour.
Watch out for Seagulls when eating outside. Wheel and deal with the waverunner vendors, they come down in price. Straw market is over rated Federico Marchetti World Cup Jersey , but you can get good deals on stuff .Also they will harass you to buy, if not interested just say 'no thank you'. Carry on your souvenirs on the plane; I had some stolen from my luggage. Dolphin Encounter is a must, worth the price to swim with them.
WASHINGTON, June 15 (Xinhua) -- Chinese scientists on Thursday reported a successful transmission of "entangled" photon pairs from space to ground stations separated by 1,200 km, a major technical breakthrough towards quantum communication over great distances.
The study, published as a cover story by the U.S. journal Science Federico Bernardeschi World Cup Jersey , distributed such "entangled" photons, or light particles, from a satellite 500 km above the Earth's surface, known as Micius, which was launched last year and equipped with specialized quantum tools.
It's another effort to prove that a physical phenomenon once described by Albert Einstein as "spooky" exists at a large distance, and eventually on a global scale.
"This work lays a reliable technical foundation for large-scale quantum networking and quantum communication experimental research, as well as experimental testing of basic principles of physics Emanuele Giaccherini World Cup Jersey , such as general theory of relativity and quantum gravity, in outer space in the future," Pan Jianwei, chief scientist for the quantum satellite project, told Xinhua.
WORLD RECORD
Quantum entanglement, which Einstein referred to as "a spooky action at a distance," is a curious phenomenon in which particles are "linked" together in such a way that they affect one another regardless of distance. It is of great significance for secure communications Eder World Cup Jersey , quantum computation and simulation, and enhanced metrology.
Yet, efforts to entangle quantum particles, such as photons, have been limited to about 100 km, mostly because the entanglement is lost as they are transmitted along optical fibers, or through open space on land Davide Astori World Cup Jersey , Pan said.
One way to overcome this issue is to break the line of transmission into smaller segments and use so-called quantum repeaters to repeatedly swap, purify and store quantum information along the optical fiber, while another approach is to make use of satellite-based technologies.
In the new study, Pan, a professor at the University of Science and Technology of China, and his colleagues used the Chinese satellite Micius to demonstrate the latter feat.
The Micius satellite was used to communicate with two ground stations 1,203 km apart Daniele Padelli World Cup Jersey , located in Delingha in northwest China's Qinghai Province and Lijiang in Yunnan Province in southwest China, separately. The distance between the orbiting satellite and the two ground stations varies from 500 to 2,000 km.
By combining so-called narrow-beam divergence with a high-bandwidth and high-precision acquiring, pointing, and tracking technique to optimize link efficiency, the team established entanglement between two single photons, separated at a distance of over 1 Claudio Marchisio World Cup Jersey ,200 km apart, for the first time, Pan said.
In addition, compared with previous methods using the best performance and most common commercial telecommunication fibers, the effective link efficiency of the satellite-based approach is 12 and 17 orders of magnitude higher respectively.
GIANT STEP
An immediate application of distributed entangled photons, said Pan, is for entanglement-based quantum key distribution to establish secure keys for quantum communication. Another is to exploit distributed entanglement to perform a variant of quantum teleportation protocol for remote preparation and control of quantum states.
According to Pan Ciro Immobile World Cup Jersey , peer reviewers of the paper praised his work as "a major technical accomplish.
