'The beautiful effect displayed by this experiment is the increase of coherence during the jump, despite its observation,' said Professor Devoret. Such jumps are undertaken by Schrödinger's cat in the famous thought experiment, which illustrated the weird and paradoxical nature of quantum theory (stock image) 'Despite that, we wanted to know if it would be possible to get an advance warning signal that a jump is about to occur imminently,' Zlatko Minev, also of Yale, added. 'Quantum jumps are known to be unpredictable in the long run.'
'These jumps occur every time we measure a qubit,' said Michel Devoret, a physicist at Yale University in the US, in a written statement. In order to develop a practical quantum computer, researchers must be able to detect and handle jumps of the qubits, which in some circumstances could represent errors in the machine's calculations. When one of these information-storing particles changes to a different energy state, it is said to have undergone a quantum jump. Quantum computers rely in storing so-called qubits of quantum information in the energy states of electrons, atoms or molecules. Pictured: an artist's cartoon of the quantum jump undertaken in the Schrödinger's cat thought experiment Schrödinger's cat might not need those nine lives after all, as researchers find that the hypothetical dead-and-alive feline's leap into a set fate can be reversed. The new findings could be used to develop error-detection systems in quantum computers, in which quantum jumps could represent mistakes in calculations. This finding overturns a cornerstone of quantum physics, which had seen quantum jumps as being instantaneous and as random as the processes that trigger them. New research suggests, however, that when atoms leap from one quantum energy state to another, they do so in a consistent and gradual manner that can be detected in advance and even reversed. This behaviour mimics our current understanding of the rules that govern sub-atomic particles, whose exact nature can be impossible to predict in advance. Shut in a box with randomly-triggered poison, the feline can be thought both dead and alive until checked on - when the cat 'leaps' into either a dead or alive state. The thought experiment of Schrödinger's cat illustrates the weird and paradoxical nature of quantum theory, exploring an effect known as superposition. Once armed with the blueprint, you can craft passes that give you access to locked rooms in Outposts and Space Stations, containing inventory upgrades and useful items.Schrödinger's cat might not need those nine lives after all, as researchers find that the hypothetical dead-and-alive feline's leap into a set fate can be reversed. You can unlock your first No Man's Sky Atlas Pass (opens in new tab) by following and progressing the Atlas Path storyline, triggered at the start of the game - don't worry if you decided to ignore the glowing red orb though, as you'll be guided down an alternate path which also yields an Atlas Pass.
