Physicists Built Quantum Machine Which Could See All Possible Futures
Do you remember that scene in the Avengers: Infinity War, when Dr. Strange looks into the future to see how the heroes could defeat Thanos? Forget about this. A group of physicists from Australia and Singapore has created a much more productive solution.
Imagine that before leaving the house in the morning, you sit down in the corridor for a moment, close your eyes and imagine all possible options that could happen with you in the next few minutes.
The researchers at Griffith University in Australia and Nanyang Institute of Technology in Singapore claim that they have managed to create a functioning quantum computer that is able to generate a superposition of all possible future options.
That’s not about the ability to predict someone’s future. The computer is able to provide all the options for the future that it itself can survive. Currently, the device can support two superpositions for 16 different probabilities.
Mile Gu, the physicist at Nanyang Institute of Technology in Singapore, is the main developer of the quantum algorithm that is the key for the computer.
One issue is important, whether we speak about future “predictions”: the possible future options grow exponentially as we look farther into the future.
If we have only two conditional probabilities to choose within one minute, in half an hour there will be 14 million variations of the future. And in a day, the number of probabilities can exceed the number of atoms in the Universe.
The quantum computer is able to analyze all these probabilities. Using quantum superposition, the machine can simultaneously review a much larger number of options than traditional computers.
The scientists created a photonic quantum information processor. Potential options for the future (the results of a choice) are displayed by the arrangement of photons in this machine.
Experiments have shown that the superposition of the quantum device is a display of multiple variants of the future, evaluated according to the degree of probability of occurrence.
The quantum computer uses much less memory than traditional computers for calculation, having a great advantage in computation power.
The authors of the research suggest that such quantum systems can help artificial intelligence to learn much faster than it does today, and thus prompt the era of quantum computers.
The scientists believe that we cannot even imagine all the implementation areas of quantum computers in the future.
Geoff Pryde, the researcher at Griffith University, tells, that current situation reminds him of the era of the birth of classic computers in the 1960s. At that time, only a few people could have imagined in which areas computers would be used in the future. As now we cannot even imagine the possibilities and prospects of quantum computers.
The team is inspired by the Nobel Laureate Richard Feynman, which is famous for the theory of quantum electrodynamics. He discovered, that when a particle travels from point A to point B – there is not only a single pat, but a particle simultaneously transverses all possible paths connecting the points.
And what do you think about all this?
