When a negative weak value −1 plays the counterpart of a probability 1
New Journal of Physics, 2016 When the weak value of a projector is 1, a quantum system behaves as in that eigenstate with probability 1. By definition, however, the weak value may take an anomalous value lying outside the range of probability like −1.

Quantum entanglement in coupled harmonic oscillator systems: from micro to macro
New Journal of Physics, 2016 We investigate the entanglement dynamics of several models of coupled harmonic oscillators, whereby a number of properties concerning entanglement have been scrutinized, such as how the environment affects entanglement of a system, and death and revival ...

The photon identification loophole in EPRB experiments: computer models with single-wing selection
Open Physics, 2017 Recent Einstein-Podolsky-Rosen-Bohm experiments [M. Giustina et al. Phys. Rev. Lett. 115, 250401 (2015); L. K. Shalm et al. Phys. Rev. Lett. 115, 250402 (2015)] that claim to be loophole free are scrutinized.

Open Physics, 2017 Bell’s stated assumptions in deriving his inequality were sufficient conditions. It is shown that a far simpler condition exists for derivation of the inequality: the mere existence of finite data sets regardless of their statistical or deterministic ...

What the complex joint probabilities observed in weak measurements can tell us about quantum physics
, 2013 Quantum mechanics does not permit joint measurements of non-commuting observables. However, it is possible to measure the weak value of a projection operator, followed by the precise measurement of a different property.

Bayesian quantum frequency estimation in presence of collective dephasing
New Journal of Physics, 2014 We advocate a Bayesian approach to optimal quantum frequency estimation—an important issue for future quantum enhanced atomic clock operation. The approach provides a clear insight into the interplay between decoherence and the extent of prior knowledge ...

True precision limits in quantum metrology
New Journal of Physics, 2015 We show that quantification of the performance of quantum-enhanced measurement schemes based on the concept of quantum Fisher information (QFI) yields results that are asymptotically equivalent to those from the rigorous Bayesian approach, provided ...
