Scientists from MIT Make Breakthrough in Quantum Technologies
Scientists from the Massachusetts Institute of Technology (MIT) made a breakthrough in the field of quantum technologies, first demonstrating control over a quantum accident. The study focused on the unique feature of quantum physics known as the “fluctuation in vacuum” (source).
Previously, fluctuations in vacuum allowed scientists to generate random numbers. The results of the MIT study were published in the journal Science (source). The article was prepared by Charles Roques-Carmes and Yannick Salamin, associated employees of MIT, along with MIRIN SOLJAčić, John Joannopoulos, and their colleagues.
Quantum Calculations from a New Angle
While traditional computers follow established rules and algorithms, probabilistic calculations offer a different approach. These systems use the inherent randomness of certain processes to perform calculations, providing a range of possible outcomes rather than a single deterministic answer. However, controlling probability distributions associated with a quantum accident has been a challenge in practical implementations.
The MIT team’s study suggests a possible solution. By introducing a weak laser “displacement” into an optical parametric generator – a system that naturally generates random numbers – scientists demonstrated control over a “displaced” quantum accident. Charles Roques-Carmes stated, “Our discovery of a controlled quantum accident allows us to revise old concepts in quantum optics and opens new possibilities in probabilistic calculations and ultra-fluid feelings.”
Prospects for the Future
Yannick Salamin emphasized the expectation that this technology will advance in the coming years, enabling the creation of high-speed photon probabilistic bits and expanding the range of applications. Professor Mit Marin Soljačić added, “By controlling fluctuations in vacuum, we push the boundaries of capabilities in quantum probabilistic calculations.”
