Quantum Control of Open Systems
Quantum systems are delicate. Unlike classical systems, they can exist in superpositions, entangle with other particles, and show interference patterns. But these beautiful quantum effects are easily disrupted by interactions….
Quantum Parameter Estimation
In both classical and quantum physics, we often want to estimate unknown parameters that describe physical systems. For example: Estimating such parameters is essential in science and engineering — particularly….
Quantum Non-Demolition Measurements
In classical physics, measuring something doesn’t change it. You can check the temperature of water or the position of a car without disturbing them. But in quantum mechanics, measurement is….
Quantum State Control Techniques
In quantum mechanics, a quantum state represents the full information about a physical system. Controlling these states with precision is essential to all areas of quantum technologies—whether it’s computing, sensing,….
