Not only does the new method solve the theoretical maths problem, but can also have practical applications \u2013 aiding in the development of the nascent quantum computing systems.<\/p>\n<p>A group of researchers from the Jagiellonian University in Poland and the Indian Institute of Technology in Madras have managed to solve the \u201cunsolvable\u201d maths problem known as \u201cEuler\u2019s officer problem\u201d using the famous Schr\u00f6dinger\u2019s cat thought experiment.<\/p>\n<p><b>In case you didn\u2019t know: Schr\u00f6dinger\u2019s cat was a thought experiment designed to show peculiarities of quantum physics. According to it, a cat in a closed box with a radioactive poison can be considered both dead and alive until the box is opened in a world of quantum physics.<\/b><\/p>\n<p>Euler\u2019s officer problem was first formulated by Leonhard Euler back in 1779 and is a maths puzzle: you operate an army of six regiments with each of them having six different officers of six different ranks; you must arrange these 36 officers in a 6-by-6 square while avoiding repeating either rank or regiment in any row or column.<\/p>\n<p>The problem was proved to be unsolvable back in 1960 using computers, which took a brute-force approach by working through all the possible variants of arranging officers. However, a group of researchers recently published a paper in which they demonstrated a way to solve this puzzle\u2026 sort of. All you have to do is to place the officers in the world of quantum physics and add a quantum entanglement into the mix.<\/p>\n<p>In the quantum world you can\u2019t really tell what regiment an officer belongs to or what rank he has. And if he is placed in a state of quantum entanglement \u2013 a physical phenomenon where groups of particles can share quantum states regardless of the distance between them \u2013 Euler\u2019s maths problem becomes solvable, according to the researchers. With the officers having neither a static regiment nor a fixed rank \u2013 and each of them entangled \u2013 the computer could find at least one arrangement of the 36 officers that would meet the terms set by Euler.<\/p>\n<p>So what does the solution of this maths-physics puzzle give us in practice? Theoretically, the method used to solve this problem can be applied in quantum computing. It can serve as a rudimentary system to safeguard such computers against mistakes in calculations and preserve the data in case of an error. According to the researchers\u2019 interview with Quanta Magazine, the absolutely maximally entangled state, which is achieved as a result of arranging these \u201cquantum officers\u201d, can be used to organise resilient data storage for quantum computers.<\/p>\n<p><strong>For More News And Analysis About <a href=\"https:\/\/www.africa-press.net\/kenya\">Kenya<\/a> Follow <a href=\"https:\/\/www.africa-press.net\/\">Africa-Press<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; Kenya.
