It’s not who we are — it’s who we are online that counts. This is a vital ideology of online video marketing promotion. In most cases, this software also protects that list from hackers, both on the local computer and over network connections. Research on misinformation and false beliefs has a long history in the psychology literature but it is only since 2017 that other fields such as computer science have started robust empirical research projects in this area. 2017), Fréchet Audio Distance Kilgour et al. In Sec. III, we turn to quantum thermodynamics and recall the set of passive states (extending the non-increasing probability vectors) together with the notion of passivity-preserving quantum operations and incoherent (and strictly incoherent) quantum operations, which are necessary for the rest to follow. The rest of the paper is organized as follows: in Sec. We conclude in Sec. In Sec. IV, we define relative passivity, namely the condition that a state is passive relative to another passive state. In Sec. V, we come back to our central question, namely the thermodynamics of work extraction. The importance of work extraction cannot be overemphasized in quantum thermodynamics.

We also characterize the passivity-preserving – and, conversely, the activity-breaking – quantum operations in terms of their Kraus decomposition. Moreover, as an example of passivity-preserving operations, we introduce what we call activity-breaking operations (ABOs) in analogy with entanglement-breaking operations. We show that any activity-breaking operation can be written as some measure and prepare channel. In particular, for a specific class of pure active states, we show that the relation we name Hoffman majorization provides a necessary and sufficient condition for state interconversion. We provide the necessary and sufficient condition for the transformation of a specific class of active pure states under RPPOs, which makes the connection with Hoffman majorization and gives it a thermodynamical meaning. II, we introduce the classical preliminaries, in particular the concept of Hoffman majorization which induces a partial order on the set of non-increasing probability vectors. ≻ is a pre order called majorization. Interestingly, for transformations of pure qubit states under strictly incoherent RPPOs, the necessary and sufficient condition based on Hoffman majorization remains true also simply for passivity-preserving operations. Hoffman majorization is a partial order defined on the set of non-increasing positive-element vectors Hoffman (1969), and thus we find here its quantum thermodynamical meaning. The partial order that we define on the set of passive states is naturally expressed in terms of virtual temperatures and therefore, we suggestively refer to it as “being virtually cooler than”.

After characterizing the convex set of virtually cooler states than a given passive state, we then consider the class of quantum operations that preserve this partial order. These should be useful to better understand the nature of the resource consisting in not being “virtually cooler than” in a thermodynamical scenario. This leads us to define the notion of a “virtually cooler” quantum state. However, such a notion of comparison is absent for passive states, which hinders the treatment of passive-environment maps going beyond thermal maps. We then introduce the notion of relative passivity-preserving operations (RPPOs) and illustrate it with an example. We call such operations as relative passivity-preserving operations and denote them as RPPOs. We then consider the question of state transformations under strictly incoherent RPPOs. If you are concerned about your competition, then just dispel those thoughts from your brain right away. POSTSUBSCRIPT are the same, then the state is necessarily a thermal state.

ABOs are defined as the operations that map any input state into the set of passive states. As a starting point, we thus introduce here a partial order on the set of passive states that allows for comparison based on their thermodynamic merits. This partial order is a stochastic order that is connected to the concept of “virtual temperature” of a quantum system Brunner et al. Given a single quantum system, two different thermal states of the system can be compared and distinguished based on their temperatures. The Competition and Markets Authority (CMA) is to be given new powers to enforce the rules by directly imposing financial penalties and awarding compensation, rather than forcing complainants to go through the courts. Considering again work extraction, we show that the ergotropy is simply achievable via passivity-preserving operations for a given class of pure active qubit states. As a consequence of this condition, 우리카지노 we also show that the maximal work extraction from a given class of pure active states, which is equal to ergotropy, is achievable with strictly incoherent RPPOs. But there are various thermodynamical contexts where one is interested in work extraction and state transformations of a quantum system interacting with its environment, which may be inaccessible to an observer in general and deviate from a thermal bath.
