The forecast in Provo shows that there is no rain in sight until August 25, but don’t get too excited as that date is ten days from now and the weather will likely change. Now, at mid-August we are officially in the height of the Atlantic Hurricane Season, but the basin is showing an all clear for at least the next two days. It was explained by the National Hurricane Center that it will be a less active season, the below normal potential has increased thanks to an El Niño factor.last_img read more

More Secure Optical Communications Via Antisqueezed Light

first_img Explore further Citation: More Secure Optical Communications Via ‘Antisqueezed’ Light (2006, October 10) retrieved 18 August 2019 from https://phys.org/news/2006-10-optical-antisqueezed.html Physicists use nanostructures to free photons for highly efficient white OLEDs Enter researchers Tatsuya Tomaru and Masashi Ban from the Hitachi Advanced Research Laboratory in Japan. Recently, they figured out that more secure optical communications can be achieved using “antisqueezed” light. Their work is described in the September 13, 2006, online edition of Physical Review A.“Antisqueezed light is tolerant of loss and amplification,” Tomaru told PhysOrg.com. “It is well suited to optical communication.”Antisqueezing, rather nonintuitively, is one side effect of a process called squeezing, which (also nonintuitively) is not the mechanical action its name implies. Rather, understanding squeezing and antisqueezing begins by understanding the quantum nature of light – that light is inherently grainy, made up of basic units, or “quanta,” called photons. And photons, like other particles, like to retain some mystery. A photon will allow either its position or its momentum to be measured with high precision – but not both. This limitation is known as the Heisenberg Uncertainty Principle.That said, squeezed light – and by extension antisqueezed light – is defined by fluctuations in the precision of the photons’ measured position and momentum. When the fluctuation (i.e. the error) of the measured momentum is “squeezed,” the fluctuation of the measured position must, in accordance with the Heisenberg Uncertainty Principle, become inflated, or “antisqueezed.”So how can this make optical communications more secure? Mathematically speaking, when squeezed light is transmitted, the larger fluctuation – the antisqueezed component – dominates, and the squeezed component regresses to the natural fluctuations light experiences in a vacuum. But the antisqueezed component resists that pull; it is always beyond the vacuum fluctuation, even after loss and amplification. The result is a signal that is far more loss-tolerant. As a result, there are far fewer lost pieces for eavesdroppers to collect.Tomaru and Ban assume real light signals that are encrypted prior to transmission, with the intended receiver equipped with the proper key to correctly un-encrypt the signal. An eavesdropping receiver would not know this key, and would be unlikely to correctly guess it. This is a common way to secure a transmission. Using antisqueezed light adds an extra measure of security.“Antisqueezing is essential to differentiating between legitimate receivers and eavesdroppers,” said Tomaru. “Eavesdropping would be very difficult under these conditions.”Citation: T.

A 74, 032312 (2006)By Laura Mgrdichian, Copyright 2006 PhysOrg.comcenter_img Using light to transmit information – optical communication – is the basis of several technologies, most commonly fiber-optic cables, which are used in imaging and telecommunications. But sending information securely using light requires minimizing and compensating for loss as the light propagates between transmitter and receiver. And in the area of security, there is always room for improvement. This document is subject to copyright.

Heat humidity trigger highest ever power demand in Kolkata

first_imgKolkata: Calcutta Electric Supply Corporation (CESC) met the highest ever demand for electricity in the city on Wednesday.It is said the demand was triggered by a soaring mercury. According to CESC, at 3:30 pm, on Wednesday, the demand of power reached up to 2319 Mega Watt (MW), which is reportedly an all-time high demand for electricity in Kolkata. According to a source, as the temperature since the past few days has been hovering around 36 degree Celsius, use of air conditioners in the households has increased which led to an increase in consumption of electricity. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataVarious shops owners claim sale of air conditioners in the past few months have gone up reasonably. Calcutta Electric Supply Corporation claimed that on May 10 at 3:45 pm demand of power had reached 2315 MW which was the highest in the summer till Wednesday. On May 18, the demand for electricity was 2228 MW whereas on the next day demand was dropped to 1732 MW. According to CESC officials, despite the summer has prolonged and the temperature is continuously rising, the Calcutta Electric Supply Corporation is ready fulfill the soaring demands of electricity even if such situations crop up in future.last_img read more

Q1 looking good says CTO with 12 increase in tourist arrivals

first_img Posted by Q1 looking good, says CTO, with 12% increase in tourist arrivals Tags: Caribbean Tourism Organization Share Travelweek Group center_img NEW YORK — The Caribbean is experiencing an arrivals boom, with 9.1 million international tourist trips recorded between January and March this year.This represents a healthy 12% increase in tourist arrivals during the first quarter, says the Caribbean Tourism Organization (CTO), which updated the media on the region’s performance during Caribbean Week New York earlier this month.The arrivals boom extended to the cruise sector as well, with a record 10.7 million cruise passenger visits, an increase of 9.9% or 900,000 more cruise arrivals when compared to the same period in 2018.This uptick was largely spurred by a 24% rise in arrivals from the United States, the Caribbean’s strongest performing market, which has been enjoying a high consumer confidence and a strong U.S. dollar. Meanwhile, Canada is also posting big numbers, with 1.5 million tourist visits that represent a 4% rise.The overall healthy growth in both stayover and cruise visits can also be attributed to a 1.4% rise in available airline seats during Q1 2019, which brought the total number of international seats to the region to 12.4 million.More news:  Direct Travel names Smith as Senior VP, Leisure Marketing, North AmericaAs such, the CTO is bullish in its forecast for the year, predicting an 8-9% increase in tourist arrivals, along with 5.5-6.5% growth in cruise arrivals.“Overall, a statistical analysis of the first quarter gives us much to celebrate as substantial numbers indicate healthy economic conditions in key source markets and a strong resurgence of tourism in destinations impacted by the 2017 hurricanes,” said CTO chairman Dominic Fedee. << Previous PostNext Post >> Thursday, June 6, 2019 last_img read more
