Researchers Reverse Time in Quantum Systems for Enhanced Tech

3/25/2026

Summary

Story summary

Researchers at Los Alamos National Laboratory developed quantum control protocols that make time appear to flow backward in quantum systems, as described in Physical Review X, and could enhance technologies such as quantum batteries.
They created a measurement engine that uses feedback to alter quantum system evolution.
Future experiments will test these protocols with superconducting qubits to explore practical applications.
The research is supported by various U.S. scientific organizations.
