8 Most Common Types of Coherent Control Techniques
Coherent control techniques are used to manipulate the quantum states of a system. These techniques have a wide range of applications in fields such as quantum computing, quantum communication, and quantum cryptography. In this article, we will discuss the 8 most common types of coherent control techniques.
1. Pulse shaping
Pulse shaping is a coherent control technique that involves manipulating the shape of the electromagnetic pulse that interacts with a system. By changing the shape of the pulse, it is possible to control the population of quantum states in the system. Pulse shaping is commonly used in quantum information processing to implement quantum gates.
2. Frequency modulation
Frequency modulation is a coherent control technique that involves changing the frequency of the electromagnetic radiation that interacts with a system. By modulating the frequency, it is possible to control the population of quantum states in the system. Frequency modulation is commonly used in spectroscopy to study the properties of molecules.
3. Phase modulation
Phase modulation is a coherent control technique that involves changing the phase of the electromagnetic radiation that interacts with a system. By modulating the phase, it is possible to control the interference between different quantum states in the system. Phase modulation is commonly used in quantum information processing to implement quantum gates.
4. Coherent population transfer
Coherent population transfer is a coherent control technique that involves transferring the population of a quantum state to another quantum state using electromagnetic radiation. This technique is commonly used in quantum information processing to implement quantum gates.
5. Stimulated Raman adiabatic passage
Stimulated Raman adiabatic passage is a coherent control technique that involves using two electromagnetic pulses to transfer the population of a quantum state to another quantum state. This technique is commonly used in quantum information processing to implement quantum gates.
