In the movie 201
"When we think of the future, we are faced with a huge set of opportunities," explains Professor Mil Gue of NTU in Singapore, who led the development of the quantum algorithm underlying the prototype. For example, even if we have only two choices from every minute, in less than half an hour there are 14 million possible feathers, and less than a day – the number of atoms in the universe. . However, he and his research team realized that the quantum computer could explore all possible perspectives by placing them in a quantum superposition – like the famous Schrödinger cat, which is both alive and dead at the same time.
joined efforts with an experimental team led by Professor Jeff Pride of the University of Griffith. Together, the team implemented a specially designed photon quantum information processor, in which potential future results of the decision-making process are represented by the arrangement of photons – quantum particles of light. They then showed that the state of the quantum device is a superposition of several potential fuzziness probes, weighted for their probability of occurrence.
"The functioning of this device is inspired by the Nobel Prize winner Richard Feynman," says Dr. Jane Thompson, a member of the Singapore team. "When Feynman began to study quantum physics, he realized that when a particle travels from point A to point B, it does not necessarily follow one path, but simultaneously crosses all possible paths that connect dots.
The machine has already demonstrated one application – measuring how far our bias towards a particular choice is currently affecting the future. "Our approach is to synthesize a quantum superposition of all possible fevers for each bias." explains Farzad Gafari, a member of the experimental team: "By interfering with these superpositions with each other, we can completely avoid individual viewing of each possible future. In fact, many modern AI (artificial intelligence) algorithms are studied, seeing how small changes in their behavior can lead to different future results, so our techniques can allow a more efficient study of the effect of their actions with quantum AI.
The team notes that their current prototype simulates no more than 16 feathers at the same time. Tzipi scale without limits. "That's what makes this exciting field," – says aspiration. "This is reminiscent of the classic computer & # 39; computers in the 1960s. Just as few could have imagined much of the use of classical computers in the 1960s, we still have not much to do with what quantum computers can do. Each opening of the new program provides a further impetus for their technological development. "
