MARKHAM (CITYNEWS) – A Gravenhurst man is recounting how he helped Wanzheu Lu, the 22-year-old who was kidnapped from his Markham condo parking garage, after he was released by his captors.The man, who didn’t want to be identified due to fears for his safety, described how his dog originally alerted him to Lu.He said he was taking his dog out when she began barking at something. He could hear a voice from the street so he decided to go out an investigate himself.“[Lu] had a dark hoodie on that had duck tape on it,” the man said.The resident said that Lu didn’t know where he was and added that he had been handcuffed at some point.Lu reportedly explained to him that he had been kidnapped and that’s when the man called 911.“He was looking quite rattled (and) super upset, which I totally understand,” the man said.He added that Lu couldn’t recall many details, “prior to being released or escaping, he had no idea where he was.”Within 10 minutes, police had arrived and Lu was taken to hospital for minor injures. He has since returned to York Region.The man said he had only heard about the story once on the radio and never expected to end at his home.“I was taken aback by it, but I just did what I had to do,” he said.He acknowledged if it weren’t for his dog he likely would not have known Lu was there and for a chilly night, Wanzheu was only dressed in a sweater and jeans.“It definitely was a stroke of luck. I guess he had a guardian angel looking out for him at some point,” the resident said.York regional police are still investigating the motive behind the “violent” kidnapping and are actively looking for four suspects involved.FULL VIDEO: Gravenhurst man describes finding Markham abduction victim Wanzheu Lu
Trust The Kapil Sharma Show to bring out the most candid and scandalous confessions from guests on his show. Something similar happened when Akshay Kumar visited the sets of Kapil’s famous show.The 51-year-old actor appeared on the show to promote his upcoming film – Mission Mangal – along with his lady gang from the film. On being asked why he doesn’t party, Akshay had quite a candid reply. He revealed that he doesn’t go out with his friends for partying as he fears he would have to pay the bill. Now, isn’t that just hilarious?Well, this was not the first time when we got to know how serious Akshay Kumar is about financial matters. On Karan Johar’s Koffee with Karan, Ranveer Singh had revealed the advice he got from Akshay Kumar early on in his career. Singh had revealed that the veteran actor had asked him to do anything for money. Akshay had said, “Mujhe paisa barbaad hote huye dekhna achha nahi lagta hai. Mujhe dekho, shaadi hai, main naach raha hoon. Birthday hai, main naach raha hoon. Mundan hai, bacha ro raha hai, main naach raha hoon.”Talking about appearing in Forbes and taking the 33rd rank of highest-paid celebrities, Akshay had told HT, “Surely, it feels good. But I just go through the headline and not the detailed copy [of such articles]. On a serious note, money does matter to me but only in a limited way. And I know it’s my hard-earned money. I work extremely hard for each and every penny. Money doesn’t come easily to you. I have put my sweat and blood for that. So, yes, it does matter to me.”Mission Mangal, which is loosely based on ISRO’s space mission Mangalyaan, stars Sonakshi Sinha, Vidya Balan, Taapsee Pannu, Kirti Kulhari and Nitya Menon in pivotal roles. The film is slated to release on August 15.
Citation: Qubits and Branes Share Surprising Features (2008, July 3) retrieved 18 August 2019 from https://phys.org/news/2008-07-qubits-branes-features.html Most recently, Duff and colleagues from Imperial College London and the Institute for Research in Fundamental Sciences in Tehran, Iran, have discovered another correlation. They’ve shown that the “branes” in string theory mathematically correlate to the qubits in quantum information theory. Their study, titled “Wrapped Branes as Qubits,” is published in a recent issue of Physical Review Letters.“These relations between black holes and qubits are still mysterious,” Duff told PhysOrg.com. “The significance of this recent paper is that, by invoking branes wrapping around the extra dimensions, it resolved the puzzle of why black holes should display any kind of two-valuedness: ‘To wrap or not to wrap; that is the qubit.’”In string theory, which requires extra dimensions, branes are theoretical objects that can be used to describe parts of the universe on a quantum scale. For instance, black holes can be described by four D3-branes intersecting at an angle, which can be useful for understanding the microscopic origins of black hole entropy.In the current study, the researchers have shown that four D3-branes can also be wrapped around the six extra dimensions of space (that exist in 10-dimensional string theory) in a way that closely resembles an entangled three-qubit state. As the physicists explained, the way that each D3-brane can wrap one way or the other around dimensions resembles the two states that a qubit can have. The researchers showed that a similar correlation exists between M2-branes, which can wrap in one of three ways around dimensions, and qutrits, which have three possible states.To mathematically demonstrate this connection, the physicists used a well-known fact from quantum information theory: a three-qubit state can be described by five parameters (four real numbers and an angle). They showed how these five parameters correspond to the four D3 branes and the branes’ angle of intersection. The work adds to a growing body of papers published in the past year on correlations between entanglement and black holes (or quantum gravity). As the physicists described, these papers are building a kind of dictionary of translations between phenomena in one language to the phenomena in the other. “When two very different areas of physics share the same mathematics, one can learn new things about each field by borrowing techniques from the other,” Duff said. “This has been a two-way pay-off and we are certain that yet more correlations will be discovered.” However, no one yet knows whether there are any physical reasons underlying these mathematical coincidences. As Duff said, “an underlying physical basis, if it exists, would be an extra bonus.”Still, understanding the mathematical correlations could be enough to lead to some interesting applications in quantum information theory.“The weird kind of numbers known as octonions have fascinated both mathematicians and physicists for decades,” Duff said. “But in their recent books, both Roger Penrose and Ray Streater have written them off as ‘lost causes in physics’ because they have so far failed to find any application. However, we believe that the tripartite entanglement of seven qubits (inspired by stringy black holes) provides a way of testing octonions in the laboratory, and this might find applications in QI, for example, in cryptography.”More information: Borsten, L.; Dahanayake, D.; Duff, M.

What do black holes and entangled particles have in common? Until about a year ago, physicists thought that the two entities existed in completely separate worlds. Then, in 2007, physicist Michael Duff from Imperial College London demonstrated a correlation between the entanglement of three qubits and the entropy of a black hole. In the past year, several studies have demonstrated even more connections. This document is subject to copyright.
