Characterizing quantum coherence

Physical Review A, 1992
For a system with canonical variables x and p, [x,p]=ih, we associate with each density operator p an x coherence δx and a p coherence δp which specify, respectively, the characteristic distance and momentum range over which the underlying quantum-mechanical nature of the ensemble cannot be neglected.

Role of Quantum Coherence in Kinetic Uncertainty Relations.

Physical Review Letters
The kinetic uncertainty relation (KUR) bounds the signal-to-noise ratio of stochastic currents in terms of the number of transitions per unit time, known as the dynamical activity.

Testing macroscopic quantum coherence

Il Nuovo Cimento B, 1995
The compatibiity of Macrorealism and Quantum Mechanics is discussed in the light of some recent experimental proposals based on non-invasive measurements realized via SQUID techniques that aim at evidentiating violation of a class of Bell-like inequalities.

Multiple Quantum Coherence Spectroscopy

The Journal of Physical Chemistry A, 2009
Multiple quantum coherences provide a powerful approach for studies of complex systems because increasing the number of quantum states in a quantum mechanical superposition state increases the selectivity of a spectroscopic measurement. We show that frequency domain multiple quantum coherence multidimensional spectroscopy can create these superposition

Classical versus quantum coherence

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2002
Quantum dots are structures engineered to have desirable quantum-mechanical properties. Much of their potential usefulness stems from the ability to design such structures so that their passive properties can be exploited. However, there are many plans to use dots as the basis of a more active quantum engineering, in which the detailed quantum states ...

Operational advantage of basis-independent quantum coherence

Europhysics letters, 2019
In the quantitative theory of quantum coherence, the amount of coherence is defined as the distance between the given state to the closest incoherent state.
