We study the detection of continuous-variable entanglement, for which most existing methods designed so far require a full specification devices, and we present protocols entanglement in scenario where measurement devices are completely uncharacterized. first generalize, to continuous variable regime, seminal results by Buscemi [Phys. Rev. Lett. 108, 200401 (2012)] Branciard et al. 110, 060405 ...

Continuous-variable measurement-based quantum computation on cluster states has in recent years shown great potential for scalable, universal, and fault-tolerant when combined with the Gottesman-Kitaev-Preskill (GKP) code error correction. However, no complete architecture exists that includes everything from cluster-state generation finite squeezing to gate implementations realistic noise In t...

Latent variable models are common in the social sciences to measure ideal points of U.S. Senators, countries’ “level of democracy” or the relationships between latent attitudes and values across countries, for instance. Because differences in measurement parameters can be confounded with substantively interesting differences, measurement invariance or “equivalence” is a prerequisite for cross-g...

An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...
