Jose Mourinho is hungry for points as Manchester United look to get their top-four Premier League hopes back on track against Fulham on SaturdayThe Red Devils are on a four-match winless run in the English top-flight and find themselves already 18 points adrift of leaders Manchester City after Wednesday’s 2-2 draw with Arsenal.With hopes of a Premier League title now practically over, United’s main goal for this season is to seal a top-four finish.But they are eight points behind fourth-place Chelsea and must return to winning ways immediately.Although Mourinho concedes that, even against bottom-side Fulham, nothing is guaranteed ahead of this weekend’s showdown at Old Trafford.Maguire says United need to build on today’s win George Patchias – September 14, 2019 Harry Maguire wants his United teammates to build on the victory over Leicester City.During the summer, Harry Maguire was referred to as the ultimate…“I sat here a few weeks ago speaking about December and [having] no defeats – that’s a reality,” said the United boss, according to SportsMax.“[We have had] good fights, good spirit but just one victory against Young Boys [in the Champions League], and three draws, [but] we need points, Fulham are the same.“I want to be positive and think we are going to win, but if we don’t [win], give credit to people who deserve credit.“The game is not 11 v 0, it’s going to be 11 v 11, with good players on the other side, the position and points [total] don’t say much about [the] potential of the team.“They have one of the two most important managers in Premier League history, they have the potential to come here and give us a difficult match.”
Budget talks among House and Senate leadership staff and White House officials have made little headway as they enter their second week.“I believe that we’re nearing a point … that we’re going to have to start making some decisions,” Senate Minority Leader Harry Reid (D-Nev.) said Tuesday. So far, the two sides have started discussing possible offsets to pay for higher discretionary spending levels.While little progress has been made, top Democratic appropriators are calling on negotiators to reach agreement on a new topline spending level by early November so they have time to craft an end-of-the-year spending bill by the Dec. 11 expiration date of the current continuing resolution, reports CQ.The overarching goal for Democrats is to strike a deal to raise the Budget Control Act spending caps for fiscal 2016 and 2017 before House Speaker John Boehner (R-Ohio) steps down at the end of the month. With House GOP leadership elections dominating conversation through the end of the month, it’s not clear how much progress can be achieved, though.The negotiations are at the staff level for now, but at some point will involve Republican and Democratic leadership, with appropriators left on the sidelines.“This is being negotiated at the leadership level. This is being done by Harry Reid, [Nancy] Pelosi, [Mitch] McConnell, etcetera. What I’m providing, as is Congresswoman [Lowey], we’re providing technical assistance and advice to our leadership as they negotiate, whether it’s on offsets, the status of touchy subjects in bills and so on,” Barbara Mikulski (D-Md.), ranking Democrat on Senate Appropriations, told CQ.

In spite of the overwhelming success of LG’s Nexus 4 smartphone, the company on Tuesday said it has no plans for the next generation Nexus device so far.A few hours after LG rolled out its much anticipated white Nexus 4 variant to the global market, Korean smartphone maker put the rumours of the next generation Nexus smartphone to rest. In a report published by Dutch website All About Phones, LG Mobile’s European Vice President Kim Wong said the company does not wish recreate the success of Nexus 4, making it clear that it does not have plans for its next collaboration.”There are currently no plans for a Nexus 5 made by us. We don’t need that kind of marketing exposure anymore. The Nexus 4 was a great success, even with the supply issues and we have a great relationship with Google. But we won’t make the Nexus 5,” revealed Kim Wong.The latest revelation from the smartphone maker came at a time when reports of Google-LG collaboration for the next Nexus device are doing the rounds.LG also confirmed that it will not be launching any smartphones featuring flexible displays this year, as the technology is still being developed.The report also quoted Wong as saying, “The tablet market is currently fairly segmented; nevertheless we continue to invest in it.” He mentioned that LG is prepping an Android tablet for the lucrative tablet market, but did not reveal its availability.

In an ironic twist, physicists have shown that the very property that can be used to show that quantum computing devices can solve some problems that classical computers cannot also makes it impossible to efficiently certify that this “quantum supremacy” has indeed been achieved, for a wide variety of schemes. In quantum computing, the issue of certification is crucial for formally verifying the superior computing power of quantum devices.

Our work also points towards a potential way out of this dilemma: interactive or quantum certification protocols.”The term “quantum supremacy” refers to the possibility that quantum computing devices can solve some problems that are practically infeasible for classical computers to solve. One problem that is considered intractable for classical computers is random sampling from certain very flat distributions (in which all outcomes are nearly equally likely) over exponentially large datasets. Currently, no universal, fault-tolerant quantum computer is available to experiment with, but even the limited quantum devices that are available today are thought to be capable of performing the random sampling task. Intuitively, this is because quantum devices can prepare a state in the correct superposition of all elements of a set, while classical devices need to access the exponentially many probabilities one by one. One of the limitations of all physical devices (quantum or classical) is that they are only capable of approximate sampling. So in order to demonstrate quantum supremacy, researchers must show that a quantum device’s approximate sampling is close enough to ideal sampling so that it is still intractable for classical computers. All current proofs of this concept, which is called approximate sampling hardness, use small second moments. In the random sampling task, a distribution is randomly chosen. Essentially, small second moments mean that the randomly chosen distribution concentrates around the uniform distribution and is therefore very flat. In the new paper, the researchers show that small second moments also forbid efficient certification from the samples alone. That is, sampling distributions with small second moments cannot be certified with polynomially many samples, but instead require exponentially many samples. This makes certification inefficient and unrealistic to perform in a reasonable amount of time. The results hold for a variety of widely used sampling schemes, including boson sampling and universal random circuit sampling, among others. However, the results do not mean that efficient certification is necessarily impossible by any method. The researchers hope that, instead, the findings will motivate the development of alternative certification schemes, as well as proofs of approximate sampling hardness that apply to distributions with larger second moments. “Our work guides the way for where to look for feasible certification schemes,” Hangleiter said. “In particular, it often makes sense to use device-specific knowledge to leverage certification. One direction of research is to develop device-specific certification schemes both for quantum sampling schemes, but thinking further, also for more elaborate tasks that can be performed on quantum computers. “Quantum sampling schemes are very ‘clean’ quantum supremacy proposals in the sense that they allow for a complexity-theoretic hardness argument. At the same time, they do not have real applications (yet). A second direction of research is to develop schemes that are feasible on near-term devices and yet hard, which also solve a useful task, as well as to find applications for the known sampling schemes.” A test to certify quantum supremacy will accept a probability distribution if it is classically hard, and otherwise will reject it.
