Scientists have experimentally remedied quantum uncertainty, achieving an accuracy previously considered impossible according to Heisenberg’s principle.
Physical in Australia and the United Kingdom have demonstrated a way to remodel quantum uncertainty, surrounding one of the most famous restrictions of physics: Heisenberg’s principle of uncertainty.
O, published on September 24 at Science Advances, can pave the way ultrasensible sensors With applications in navigation, medicine and astronomy.
First formulated in 1927, the principle of uncertainty It states that it is impossible to know certain pairs of properties – such as the position and moment of a particle – with unlimited accuracy at the same time. The more precisely one is measured, the less precisely the other can be known.
A team of physicists, led by Tingrei Tan of the Nano Institute of the University of Sydney, showed that this Compensation can be restructured. “Think of uncertainty like air in a balloon,” explained Tan. “You can’t get rid of it without bursting the balloon, but you can fit it into places that don’t interest you. That’s what we did.”
By transferring uncertainty to rude and less useful information, researchers have obtained more accurate measurements of the small details that matter. Compared it to a Clock with only one pointer: The time pointer provides approximate minutes, but with a good context, while the minute pointer provides precise minutes but without hours. Your approach essentially combines the benefits of both, explains the.
The first experimental demonstration was carried out using imprisonedparticles that vibrate like a quantum pendulum. By preparing them in “grill states”, originally designed for the correction of quantum errors, the team measured the position and moment with precision beyond the so-called standard quantum limit.
“We have not broken the principle of Heisenberg,” said co -author Dr. Ben Baragiola of Rmit University. “Instead, We optimize quantum mechanicsexchanging global information for an unprecedented sensitivity to small changes. ”
The implications are comprehensive. Improved quantum sensors could guide submarines or spaceships In environments where GPS fails, improving biological and medical images, detecting gravitational fluctuations and investigating fundamental physics. “Just as atomic watches have transformed navigation and telecommunications, quantum sensors can make totally new industries viable,” said Christophe Valahu, the first author of the study.
