Quantum guitar: Scientists decode 90-year-old mystery of damped harmonic oscillator

SMRTR summary

Physicists have solved a long-standing quantum mechanics puzzle by creating the first exact solution for a damped quantum harmonic oscillator. The breakthrough explains how atoms lose energy while maintaining Heisenberg's uncertainty principle. Researchers discovered atoms settle into a "multimode squeezed vacuum" state that preserves quantum rules while allowing energy dissipation. This advancement could lead to ultra-precise measurements beyond the standard quantum limit, potentially creating sensors capable of detecting subatomic movements.
