    Mar 22, 2024A bath with a negative temperature is a subject of intense debate in recent times. It raises fundamental questions not only on our understanding of negative temperature of a bath in connection with thermodynamics but also on the possibilities of constructing devices using such baths. In this work, we study steady-state quantum thermodynamics involving baths with negative temperatures. A bath ...

    steady-state quantum thermodynamics with negative temperatures. We show that the zeroth and the Clausius state of the second law remain unaltered in the case of baths with negative temperatures. However, the Kelvin-Planck statement of the second law updates in this case to incorporate the following. (i) There is spontaneous

    Mar 22, 2024In this work, we study steady-state quantum thermodynamics involving baths with negative temperatures. A bath with a negative temperature is created synthetically using two baths of positive temperatures and weakly coupling these with a qutrit system. These baths are then coupled to each other via a working system. At steady state, the laws of ...

    Figure 1. A synthetic bath is created using two baths with different temperatures and letting them interact with a qutrit system. In particular, the hot bath (H) with inverse temperature βH is weakly coupled to the energy eigenstates |1〉 and |3〉. The cold bath (C) with inverse temperature βC weakly interacts with the energy eigenstates |2〉 and |3〉. As a result, the populations of the ...

    May 2, 2023At steady-state, the laws of thermodynamics are analyzed. We find that whenever the temperatures of these synthetic baths are identical, there is no heat flow, which reaffirms the zeroth law.

    Transforming the Landscape for programmable Quantum Simulation in Europe. Building on the achievements of the European Quantum Flagship project PASQuanS (2018-2022), PASQuanS2 sets out to further advance and scale up quantum simulation platforms based on atoms and ions, and stimulate a vibrant ecosystem for quantum simulation across Europe.

    Apr 11, 2023Following a two-stage approach, PASQuanS2 is now kicking off its first project phase: the so-called PASQuanS2.1. Running for the next 3.5 years, one of the major objectives of this initial phase is the development of quantum simulators with at least 2,000 atoms and a path towards 10,000 while improving control, stability, and scalability.
