The problem of demonstrating entanglement is central to quantum information processing applications. Resorting to standard entanglement witnesses requires one to perfectly trust the implementation of the measurements to be performed on the entangled state, which may be an unjustified assumption. Inspired by the recent work of F. Buscemi [Phys. Rev. Lett. 108, 200401 (2012)], we introduce the co...

Dimension witnesses allow one to test the dimension of an unknown physical system in a device-independent manner, that is, without placing assumptions about the functioning of the devices used in the experiment. Here we present simple and general dimension witnesses for quantum systems of arbitrary Hilbert space dimension. Our approach is deeply connected to the problem of quantum state discrim...

In England and Wales, in accordance with the adversarial principle of orality, witnesses in criminal proceedings are generally required to give evidence ‘live’ in open court. It is, nevertheless, now widely accepted that this obligation can place onerous demands on witnesses and militates against receipt of the best evidence potentially available in some cases. For victims of rape, the process ...

The purpose of this qualitative research is to explore the perceptions Polish judges and prosecutors regarding role psychologist expert witnesses in evaluation eyewitness testimony. Two main questions were formulated: What are criteria for selecting participate interviews then formulate opinions? do expect from their evaluations testimony? In-depth conducted involving (N = 31) 30), both male 35...

Lee Elder Jehovah’s Witnesses read with interest the case study by Sniecinski et al. (1) concerning advances in treating patients who refuse certain products made from blood. Some Jehovah’s Witnesses fit this profile. Accordingly, we are grateful to medical science for advances facilitating safe perioperative care for patients with this preference. Sniecinski et al. (1) report the cases of two ...

testimony is one of the most important reasons that legislator has accounted for proving the litigation and it is of special importance. witness is the most important pillar of testimony. due to great and special influence of testimony to prove or disprove the litigations, it is necessary to qualify the witness. one of the most important qualifications of the witness is his justice. justice is ...

Nuclear copies of mitochondrial DNA (mtDNA) have contaminated PCR-based mitochondrial studies of over 64 different animal species. Since the last review of these nuclear mitochondrial pseudogenes (Numts) in animals, Numts have been found in 53 of the species studied. The recent evidence suggests that Numts are not equally abundant in all species, for example they are more common in plants than ...

The class QMA plays a fundamental role in quantum complexity theory and it has found surprising connections to condensed matter physics and in particular in the study of the minimum energy of quantum systems. In this paper, we further investigate the class QMA and its related class QCMA by asking what makes quantum witnesses potentially more powerful than classical ones. We provide a definition...
