JPMorgan has managed to generate really random numbers. The questions are what he needs them for and how he has done it

A classic computer cannot generate Really random numbers. The algorithms used in computer science to produce this type of numbers resort to an initial value usually known as “seed”, so that making mathematical calculations with it is possible Generate one or several pseudo -elementary numbers. In this context it is necessary to use the ‘pseudo’ prefix because the need to resort to that initial value, to that seed, causes the numbers that we obtain Don’t be really random. In fact, when taking the seed we have several options. Some algorithms resort to the system clock, and it is even possible to increase the apparent randomness of the generated numbers sequence using entropy sourcessuch as the mouse movement or the temperature of the CPU in a certain moment. Even so, the numbers that we will obtain will not be really random because it is possible to predict them if we know the seed and the operations that have been carried out to generate them. Quantum computers, rescue For the gigantic American financial conglomerate JPMorgan the random numbers are very important. A priori may seem strange that a bank is interested in the procedures for generating this type of numbers, but, in reality, this capacity lies in the heart of their business. And it is that random numbers are fundamental in cryptography techniques Employees, for example, to transmit encrypted information, work with cryptocurrencies, develop gambling, and, in general, in any process in which it is necessary to have a randomly as possible randomness. To test their plan they executed their algorithm on a quantum computer of 56 cubits with ion traps manufactured by Quantinuum For this reason, in May 2023, several JPMorgan cryptographers wrote an algorithm of random generation generation that was designed to be executed in a quantum computer. Its strategy was to take advantage of the randomness inherent in the behavior of the cubits, whose functioning is governed by The rules of quantum physics, To generate bits whose randomness It could be proven afterwards. To test their plan they executed their algorithm on a quantum computer of 56 cubits with ion traps manufactured by the American company Quantinuum, which belongs to Honeywell. And it worked. They have detailed the result of their experiment in a very interesting article that they have published in Nature. To check if the numbers given by their quantum algorithm are really random JPMorgan researchers worked side by side with scientists from the National Argonne Laboratory, the National Laboratory OAK RIDGE and the University of Texas in Austin. In Your article develop the method they have used to Mathematically demonstrate using super -touches of the US Department of Energy that the numbers delivered by the quantum computer are genuinely random. “It is a revolutionary result (…) the next step requires understanding where we can apply this technology,” Asses Marco Pistoialeader of the project and head of applied research in Global Technology of JPMorgan.

The questions you have sent us (and your answers) about this mobile with an immense battery

We will answer your doubts about the Honor Magic7 Litea mid -range mobile characterized by having a good screen and camera quality, and an almost inexhaustible battery. We have been testing it several days, and now we bring you a video with all the answers to the questions that you have been sending us about it in Our Instagram profile. Q & A Honor Magic7 Lite With so many smartphone models in the market, we start answering the question about what is its main strong point. Apart from the battery, which we will talk about later, This device shines for its resistance. It has an IP64, although despite that it can be submerged for a few seconds without spoiling. If we fall to the ground, it supports fall of two meters. Its screen is a 6.78 -inch AMOLED with a resolution of 2,700 x 1,224 pixels, and a 4,000 nits peak shine. The panel looks good and with good sharpness, and thanks to its brightness you have no problem using it on sunny days. Then we respond to A Lightning Question Roundspecifying what its processor, its RAM, internal storage with its two versions, its compatibility with NFC, its doublesim, and its prices. The mobile also has artificial intelligence functionsas options to share texts and images from one application to another. It also has parallel spaces, with two separate and independent sessions. There are also smart foldersin which the mobile recommends some apps or others depending on the time that is and the uses or schedules you make of the device. We also talk about their cameraswith a module that we detail your cameras and abilities. We also show you examples of the photographs we have taken with him. And finally, we also tell you about Its surprising 6,600 mah battery. This is well above the average, and offers us a spectacular autonomy of more than two and a half days, with between 12 and 14 hours of active screen. Then we focus on the operating system and many other questions. But the best thing is that you watch the video to see all the answers.

Maybe you just need to ask yourself the five appropriate questions

Face one crowded with tasks Oa a large project can become intimidating. Therefore, when you feel that you block yourself and your productivity stagnates, it may be a good idea to rethink if you really find yourself In a productivity bump Or yes, really, those tasks are as priority as you think. Stop, step back and analyze the stage is the best way to optimize the processes to move forward, dedicating energy to what really matters to achieve the objectives and leave aside what does not. The key is to be done The right questions. When was the last time you felt productive? People are not machines, so productivity does not remain unchanged and suffers up and down throughout the week or months. It depends on your physical, emotional state. Ask that question allows you to define productivity scenarios in the past, which may not be given in the present. Remember when was the last time you felt Your productivity had shot and analyze that scenario can help you replicate that scenario in the present and promote a situation in which your productivity returns to its acceptable levels. If, for example, it was before a vacation, given the urgency of closing the fronts open before going vacation, it could be justified with The Yerkes-Dodson Lawand you need a certain voltage component that motivates you. Maybe your productivity improved when you had a well -defined goal and allowed you to focus 100% on it, instead of dispersing your attention in secondary tasks. What is the purpose of this? The day -to -day inertia often puts trees on the road that prevent seeing the full forest. One of those “trees” are the smallest and most monotonous tasks for which it is difficult to find a motivation to do. Zero of the mail, wash the dirty dishes or introduce the data of your expenses in a spreadsheet may seem boring and unproductive tasks when analyzing themselves, but acquire importance when contextualize in a broader objective. Zeroing your email tray does not have an immediate effect on your productivity since it does not make your task list It is completed faster. Instead, it does allow you to locate the important emails for your project and respond efficiently. Similarly, wash the dishes As you get dirty It serves to use less time preventing them from accumulating, in addition to avoiding health and order problems. In the same way, something as little appealable as bringing daily control of expenses It serves to improve your economy and Facilitate savings. There are only three examples of tasks that, in themselves, may seem unnecessary and totally postponable, but that have a much more important objective. It’s just a matter of giving them perspective. Why don’t I want to do this? The procrastination is A psychological phenomenon Fascinating, because whoever suffers it is totally aware of the suffering that will cause it to postpone tasks, but cannot avoid doing so. Fuschia M. Siroisprofessor of the Department of Psychology at the University of Durham, declared to The Washington Post: “Procrastination has to do with emotional self -regulation and, in particular, with the inability to handle negative moods around a certain task.” In general, we do not postpone the fun things, we procrastine in tasks that we consider “difficult, unpleasant, aversive or simply boring or stressful,” said the teacher. Find the Origin of procrastination that causes that task is one of the keys to recover productivity and face Strategies to mitigate that blockade. It may be because the task seems boring, because it is so great that facing it produces anxiety or, simply, because it does not align with your opinion. Can I break this project more? One of the most common productivity problems is the blockade that occurs before a project that we consider to surpasses us. There are so many things to do, that the focus is lost and you scatter. The best strategy to face is “Divide and win”: break down a very big task in others much smaller and assumed. For themselves, these tasks do not imply a substantial advance in the project, but as the sayinger says: “Grain does not make a barn, but helps the partner”, so that, when completing small tasks, the main project is being completed. Become your own assistant It is also a very useful technique to unlock those tasks that, for some reason, you resist facing. This technique is to prepare everything necessary (materials, data, knowledge, etc.). Once all the pieces gathered, you just have to take the step of joining them, reducing the friction of the beginning. Is this task really necessary? This is a fairly dangerous question because it requires to put the task in a certain context of priorities with respect to other tasks, and there is a risk that the Conditioning of procrastination Do not lead to an erroneous self -suction conclusion. I do not want to do it, it is not necessary. Taking that into account, it should be put on the table A priority scale And consider whether to complete a certain task is a priority to advance your project. It does not imply that the task should not be done. The question is, should you do now, today or do you have to do it? Eliminating these tasks or prioritizing others will allow you to concentrate better in your day and advances in your goal. To establish these priorities you can use task lists systems such as ABCDE METHOD. Another approach to avoid unnecessary tasks or that do not contribute to improving your productivity is simply, say no. Assume tasks that distract your attention or do not correspond to youmake your daily planning be filled with tasks that do not help you achieve your goals. The most common result is to have that feeling of not having stopped throughout the day, but you have not achieved your goals. Does it sound to you?
