Researchers extend quantum amplification to Floquet systems

Detection of weak signals is a crucial step in the verification of physics hypotheses and making breakthroughs in cutting-edge and fundamental physics research. However, if the signals are too weak to measure, they need enhancement. One attractive way to amplify the signals is quantum amplification. The state-of-the-art quantum amplification techniques still have some limitations because they rely on the inherent discrete state transitions of atoms and molecules and therefore lack tunability, us...
