Surpassing Quantum Noise Limits with Nonlinear Amplification

Ya-Long Ren, Rong-Teng Cao, Sheng-Li Ma +4

Linear quantum amplifiers are indispensable tools for quantum technologies, yet their performance is fundamentally limited by quantum noise, precluding any signal-to-noise ratio (S…

Geometric Optimization of Quantum Control with Minimum Cost

Chengming Tan, Yuhao Cai, Jinyi Zhang +3

We investigate the optimization of quantum control from a differential geometric perspective. In our approach, optimal control minimizes the cost associated with evolving a quantum…
