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/s41534-025-01069-y
Abstract: We generalize the projection–based quantum measurement–driven k–SAT algorithm of Benjamin, Zhao, and Fitzsimons1 to arbitrary strength quantum measurements, including the limit of continuous monitoring. In doing so, we clarify that this algorithm is a particular… 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.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.
