'The secret of the enormous efficiency and performance expected of future quantum computers is to be found in this superposition of states.' 'Qubits in the cat state are considered extremely important for the development of quantum technologies,' explains Jian Cui, a physicist from the Peter GrГјnberg Institute at JГјlich, in a press statement. Within 20 qubits, there are over a million states of superposition. But quantum mechanics allows qubits to exist in a coherent state of superposition, which is what the researchers wanted to explore.

The newest case: A team of German, Italian, and American researchers just built the actual experiment with twenty qubitsвЃ -units of quantum information, like a binary bit displaying a 0 or a 1 as information.Д«inary bits can only be processed in a linear fashion, reading a 0 after a 1 in a certain pattern. SchrГ¶dinger meant for his scenario to mock quantum superposition, but in time, many physicists began to see the cat paradox as far less ridiculous than he imagined. There is a difference between a shaky or out-of-focus photograph and a snapshot of clouds and fog banks. In itself, it would not embody anything unclear or contradictory. That prevents us from so naively accepting as valid a 'blurred model' for representing reality. It is typical of these cases that an indeterminacy originally restricted to the atomic domain becomes transformed into macroscopic indeterminacy, which can then be resolved by direct observation. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts. The first atomic decay would have poisoned it. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in a Geiger counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none if it happens, the counter tube discharges and through a relay releases a hammer that shatters a small flask of hydrocyanic acid. To mock this idea, he created his own scenario, which he called 'Cat Paradox': One can even set up quite ridiculous cases. SchrГ¶dinger wasn't a fan of the then-current understanding of quantum mechanics, which posited the idea of quantum superposition occurring until particles interacted with or were observed by the external world. The concept can be seen in the regular-sized world as well, in everything from water ripples on a lake to noise-canceling headphones. Now a new study looks at how the cat in the famous puzzle could exist through a bit of quantum trickery.ДЇirst, let's recap 'SchrГ¶dinger's Cat.' In 1935, Austrian physicist Erwin SchrГ¶dinger was looking at a concept called a 'superposition.' Superposition is when two waves meet and overlap and interact, which can lead to different results based on the circumstances. The thought experiment captured the general imagination, with scientists today still working to answer its challenges. Quantum mechanics often has difficulty breaking through to the general public, which is where the importance of ' SchrГ¶dinger's Cat' lies.

Now researchers have built the experiment on the quantum level using qubits.

However, quantum scientists have long seen the thought experiment as a challenge.'SchrГ¶dinger's Cat' was originally meant to mock quantum theory.
