What does an observed quantum system reveal to its observer ? [PDF]
, 2000 The evolution of a quantum system under observation becomes retarded or even impeded. We review this ``quantum Zeno effect'' in the light of the criticism that has been raised upon a previous attempt to demonstrate it, of later reexaminations of both the

Second sound with ultracold atoms: a brief review
AAPPS Bulletin, 2022 We briefly review the research on second sound in ultracold atomic physics, with emphasis on strongly interacting unitary Fermi gases with infinitely large s-wave scattering length.

Observing different quantum trajectories in cavity QED [PDF]
, 2011 The experimental observation of quantum jumps is an example of single open quantum systems that, when monitored, evolve in terms of stochastic trajectories conditioned on measurements results.

Interacting Quantum Observables
, 2008 We formalise the constructive content of an essential feature of quantum mechanics: the interaction of complementary quantum observables, and information flow mediated by them. Using a general categorical formulation, we show that pairs of mutually unbiased quantum observables form bialgebra-like structures.

Observation of Quantum Spin Noise in a 1D Light-Atoms Quantum Interface
Physical Review X, 2018 We observe collective quantum spin states of an ensemble of atoms in a one-dimensional light-atom interface. Strings of hundreds of cesium atoms trapped in the evanescent field of a tapered nanofiber are prepared in a coherent spin state, a superposition

Analyzing WMAP Observation by Quantum Gravity
, 2007 The angular power spectra of cosmic microwave background are analyzed under the light of the evolutional scenario of the universe based on the renormalizable quantum theory of gravity in four dimensions.

Loop Quantum Gravity and Observations [PDF]
, 2017 Quantum gravity has long been thought to be completely decoupled from experiments or observations. Although it is true that smoking guns are still missing, there are now serious hopes that quantum gravity phenomena might be tested. We review here some possible ways to observe loop quantum gravity effects either in the framework of cosmology or in ...

Continuous Non-Demolition Observation, Quantum Filtering and Optimal Estimation
, 1991 A quantum stochastic model for an open dynamical system (quantum receiver) and output multi-channel of observation with an additive nonvacuum quantum noise is given.

Kybernetes, 2005 PurposeAs any attempts at explaining quantum theory in terms of simple, local “cause‐and‐effect” models have remained unsatisfactory, approaches from the perspectives of systems theory seem called for, which is rich in a variety of more complex understandings of causality.Design/methodology/approachThis paper presents one option for such approaches ...
