Another constructive approach is based on adiabtic ideas.
Written by two of the world's leading researchers in the field, this is a systematic introduction to the fundamental principles of coherent control. Description. Written by two of the world's leading researchers in the field, this is a systematic introduction to the fundamental principles of coherent control, and to.
The most well studied method is Stimulated raman adiabatic passage STIRAP [22] which employs an auxiliary state to achieve complete state-to-state population transfer. One of the most prolific generic pulse shapes is a chirped pulse a pulse with a varying frequency in time.
Optimal control as applied in coherent control seeks the optimal control field for steering a quantum system to its objective. The time dependent control Hamiltonian has the typical form:. A new objective functional is defined. Finding a solution requires an iterative approach. Different algorithms have been applied for obtaining the control field such as the Krotov method.
A local in time alternative method has been developed, [26] where at each time step the field is calculated to direct the state to the target. A related method has been called tracking [27].
Coherent control has been applied to unimolecular chemical reactions controlling the final outcome [28]. Coherent control has been applied to bimolecular chemical reactions. Coherent control has been applied to biological photoisomerization of Retinal.
Coherent control has been applied in the field of nuclear magnetic resonance NMR. Coherent control has been applied in the field of ultracold matter for photoassociation [34] and for laser cooling of internal degrees of freedom. Applications of coherent control to quantum information processing [37] [38]. An important issue is the spectral selectivity of two photon coherent control.
Coherent control has been applied in attosecond physics. As one of the cornerstones for enabling quantum technologies, optimal quantum control keeps evolving and expanding into areas as diverse as quantum-enhanced sensing, manipulation of single spins, photons, or atoms, optical spectroscopy, photochemistry, magnetic resonance spectroscopy as well as medical imaging , quantum information processing and quantum simulation.
