DOI: 10.1007/s10701-019-00305-8
Abstract: The Wigner’s friend type of thought experiments manifest the conceptual challenge on how different observers can have consistent descriptions of a quantum measurement event. In this paper, we analyze the extended version of Wigner’s friend… read more here.

DOI: 10.1038/s41598-019-43250-2
Abstract: Quantum measurement is a fundamental cornerstone of experimental quantum computations. The main issues in current quantum measurement strategies are the high number of measurement rounds to determine a global optimal measurement output and the low… read more here.

DOI: 10.1080/00107514.2017.1371231
Abstract: Quantum Measurement. The four authors, one from the UK and three from Finland, do an admirable job of summarising the mathematical prerequisites (of which there are many) of a quantum theory of measurement, and expound… read more here.

DOI: 10.1103/physrevb.105.014421
Abstract: We study a device composed of an optical interferometer integrated with a ferri-magnetic sphere resonator (FSR). Magneto-optic coupling can be employed in such a device to manipulate entanglement between optical pulses that are injected into… read more here.

DOI: 10.1103/physrevd.98.065015
Abstract: It has been suggested that dark matter is a superfluid of particles whose masses are on the rough order of $10^{-22}$ eV. Since the occupation numbers are huge, the state is coherent, and the speeds… read more here.

DOI: 10.1103/physrevlett.118.103601
Abstract: A process which strongly amplifies both quadrature amplitudes of an oscillatory signal necessarily adds noise. Alternatively, if the information in one quadrature is lost in phase-sensitive amplification, it is possible to completely reconstruct the other… read more here.

DOI: 10.1103/physrevlett.124.080401
Abstract: The existence of ideal quantum measurements is one of the fundamental predictions of quantum mechanics. In theory, an ideal measurement projects a quantum state onto the eigenbasis of the measurement observable, while preserving coherences between… read more here.

DOI: 10.1103/physrevlett.128.040404
Abstract: We demonstrate the single-shot confidence estimation for individual quantum measurement outcomes using the continuous measurement theory of the quantum counting process applied to the quantum state identification problem. We experimentally obtain single-shot and average confidences… read more here.

DOI: 10.3390/e22020161
Abstract: The quantum measurement incompatibility is a distinctive feature of quantum mechanics. We investigate the incompatibility of a set of general measurements and classify the incompatibility by the hierarchy of compatibilities of its subsets. By using… read more here.

DOI: 10.3390/e23091197
Abstract: This article reconsiders the concept of physical reality in quantum theory and the concept of quantum measurement, following Bohr, whose analysis of quantum measurement led him to his concept of a (quantum) “phenomenon,” referring to… read more here.
