Incoherent control of locally controllable quantum systems [PDF]
The Journal of Chemical Physics, 2008 An incoherent control scheme for state control of locally controllable quantum systems is proposed. This scheme includes three steps: (1) amplitude amplification of the initial state by a suitable unitary transformation, (2) projective measurement of the amplified state, and (3) final optimization by a unitary controlled transformation.

Competitive Public Procurement during COVID-19: The Unique Political and Policy Experience of the United States [PDF]
European Journal of Public Procurement Markets, 2021 COVID-19 appeared during one of the most turbulent political environments in U.S. history. This research documents how political polarization during a presidential election year coincided with an incoherent national policy and procurement response to the

Controllable nonlinear propagation of partially incoherent Airy beams
Optics Express, 2023 The self-accelerating beams such as the Airy beam show great potentials in many applications including optical manipulation, imaging and communication. However, their superior features during linear propagation could be easily corrupted by optical nonlinearity or spatial incoherence individually.

Quantum Reports, 2023 Quantum systems with dynamical symmetries have conserved quantities that are preserved under coherent control. Therefore, such systems cannot be completely controlled by means of only coherent control.

Selective excitation of subwavelength atomic clouds
Physical Review Research, 2021 A dense cloud of atoms with randomly changing positions exhibits coherent and incoherent scattering. We show that an atomic cloud of subwavelength dimensions can be modeled as a single scatterer where both coherent and incoherent components of the ...
