Generalized parity measurements

Measurements play an important role in quantum computing (QC), by either providing the nonlinearity required for two-qubit gates (linear optics QC), or by implementing a quantum algorithm using single-qubit measurements on a highly entangled initial state (cluster state QC). Parity measurements can be used as building blocks for preparing arbitrary stabilizer states, and, together with 1-qubit gates are universal for quantum computing. Here we generalize parity gates by using a higher dimensional (qudit) ancilla. This enables us to go beyond the stabilizer/graph state formalism and prepare other types of multi-particle entangled states. The generalized parity module introduced here can prepare in one-shot, heralded by the outcome of the ancilla, a large class of entangled states, including GHZ_n, W_n, Dicke states D_{n,k}, and, more generally, certain sums of Dicke states, like G_n states used in secret sharing. For W_n states it provides an exponential gain compared to linear optics based methods.Comment: 7 pages, 1 fig; updated to the published versio

The impact of the new civil code on the associative forms without legal entity in the agricultural field

The legal system of the forms of deployment of the activities in the agricultural domain is regulated by Law no. 36/1991 on agricultural establishments and other forms of association in the agricultural field, amended by Government Emergency Ordinance No. 125/2006 starting with 26.05.2007. Once with the entrance into force of the Law no. 287/2009, completed and amended by Law no. 71/2011 (the New Romanian Civil Code), republished (O.G. no. 505/15.07.2011), interferes the implicit amendment of the legal system of the forms of association in the agricultural field. Traditionally, the activities in the agricultural filed have been considered a part of the civil field, yet, once with the transition from the dualist to the monist system in the Romanian national regulation, the delimitation is no longer relevant. Agricultural exploitations, regardless their dimension, can be organized either under the form of establishments with legal entity (in such manner they are enlisted by the Law no. 31/1990, republished), or the form of establishments without legal entity (respectively the limited partnership or the association of participation regulated by the New Civil Code), irrespective of, at least at the inferior level of agricultural surfaces held, by the form regulated by the GEO OUG no. 44/2008 (respectively those of the entrepreneur natural person, whose activity is conducted under the form o self-employed person, sole proprietorship or a family partnership). From the perspective of the amendments brought by the Fiscal Code, it can be outlined a decreasing tendency of the options for the classic forms of association, with legal entity, in favor of other partnerships, which taxation system id is less constrictive

MAXIMIZING THE VALUE OF LINKEDIN FOR EMPLOYER BRANDING AND REPUTATION MANAGEMENT OF SMALL BUSINESSES

This paper explores the importance of employer branding and reputation management for businesses. It focuses on small business owners'perceptions of LinkedIn as a tool for building and managing their employer brand and reputation. To highlight this, the authors conducted semi-structured in-depth interviews to identify the challenges small business owners face in using LinkedIn effectively for employer branding and reputation management, to explore best practices and strategies for leveraging LinkedIn, to enhance employer brand and reputation and last but not least, to identify the benefits of employee advocacy on LinkedIn for small businesses
