Researchers from Bauman Moscow State Technical University and the A.M. Prokhorov General Physics Institute have unveiled a groundbreaking laser system capable of generating up to 14 ultrashort laser pulses, organized into soliton molecules. These stable structures consist of multiple interacting pulses, and their passage through nonlinear mediums, such as crystals, facilitates the creation of compressed entangled states, essential for quantum computing.
The primary goal of the scientists is to produce a significant number of these soliton molecules for quantum computers. Unlike traditional qubits, which lose coherence as their quantity increases, soliton molecules maintain their entangled state and exhibit resilience to errors, as explained by Ilya Orekhov, an engineer at Bauman University. This technology not only aims to enhance quantum computations but also paves the way for innovative laser systems in various fields, including dermatology.
The laser's energy source is a standard laser diode, which emits light through a ring fiber resonator to form stable molecules. Researchers have successfully regulated the number of molecules, indicating potential for scaling this technology in the future. Orekhov noted that further studies will experimentally validate the ability of these molecules to self-correct noise, enhancing their practicality for quantum computing applications.
