We analyze two ways to obtain distinguishability measures between quantum maps by employing the square root of the quantum Jensen-Shannon divergence, which forms a true distance in the space of density operators. The arising measures are the transmission distance between quantum channels and the entropic channel divergence. We investigate their mathematical properties and discuss their physical meaning. Additionally, we establish a chain rule for the entropic channel divergence, which implies the amortization collapse, a relevant result with potential applications in the field of discrimination of quantum channels and converse bounds. Finally, we analyze the distinguishability between two given Pauli channels and study exemplary Hamiltonian dynamics under decoherence.

This study presents a novel multi-heat recovery design integrated with a modified gas turbine power plant featuring a biogas-fueled oxyfuel combustion process and a CO 2 capture unit. The proposed method utilizes a multi-stage parallel-series heat recovery approach, integrating a closed Brayton cycle with a modified organic flash cycle alongside a supercritical CO 2 plant paired with a heating provider and an organic flash cycle. Engineering equation solver software is employed to model the suggested configuration, allowing for analyzing its thermodynamic, sustainability, and financial performance metrics. Additionally, an artificial intelligence-aided optimization process is implemented, utilizing artificial neural networks, NSGA-II methodology, and LINMAP decision-making techniques. The optimization focuses on exergy efficiency and payback period as the objective functions. Results indicate an improvement in exergy efficiency by 5.22 percentage points over the baseline model, achieving a value of 42.15%. The payback period has also been reduced by 9.31%, demonstrating a value of 2.63 years. Under optimal conditions, the system can produce an electrical output of 1402 kW and a heating load of 206.7 kW. Furthermore, calculations demonstrate a CO 2 capture potential of 0.278 kg/s, a sustainability index of 1.73, a total net present value of 18.48 M$, and a total unit production cost of 34.83 $/GJ.

Exploring the relations between coexisting, cooperative, or competing types of ordering is a key to identify and harness the mechanisms governing the mutual interactions between them and to utilize their combined properties. We have experimentally explored the response of the charge density wave (CDW) to various antiferromagnetic, metamagnetic, and field-aligned ferromagnetic states that constitute the magnetic phase diagram of TmNiC2. The high-resolution x-ray diffraction experiment employing synchrotron radiation at low temperature and high magnetic field allowed one to follow the superstructure satellite reflections, being a sensitive probe of CDW. This investigation not only reveals direct evidence that the charge density wave avoids even a partial suppression in the antiferromagnetic ground state, but also proves that this state coexists, without any visible signatures of weakening, in the entire dome of the magnetically ordered phases, including the field-aligned ferromagnetic state. The calculations of the electronic and phonon structures support the experiment, revealing that the dominant contribution to the CDW transition stems from momentum-dependent electron-phonon coupling. We conclude that this mechanism prevents the CDW from vanishing, although the nesting conditions within the magnetically ordered phases deteriorate.

The Global Cosmic-ray Observatory (GCOS) is a proposed large-scale observatory for studying ultra-high-energy cosmic particles, including ultra-high-energy cosmic rays (UHECRs), photons, and neutrinos. Its primary goal is to characterise the properties of the highest-energy particles in Nature with unprecedented accuracy, and to identify their elusive sources. With an aperture at least a ten-fold larger than existing observatories, this next-generation facility should start operating after 2030, when present-day detectors will gradually cease their activities. Here we briefly review the scientific case motivating GCOS. We present the status of the project, preliminary ideas for its design, and some estimates of its capabilities. © Copyright owned by the author(s) under the terms of the Creative Commons.

We characterise a class of environmental noises that decrease coherent properties of quantum channels by introducing and analysing the properties of dephasing superchannels. These are defined as superchannels that affect only non-classical properties of a quantum channel E, i.e., they leave invariant the transition probabilities induced by E in the distinguished basis. We prove that such superchannels ΞC form a particular subclass of Schur-product supermaps that act on the Jamiol lkowski state J(E) of a channel E via a Schur product, J0 = J ◦ C. We also find physical realizations of general ΞC through a pre- and post-processing employing dephasing channels with memory, and show that memory plays a non-trivial role for quantum systems of dimension d > 2. Moreover, we prove that coherence generating power of a general quantum channel is a monotone under dephasing superchannels. Finally, we analyse the effect dephasing noise can have on a quantum channel E by investigating the number of distinguishable channels that E can be mapped to by a family of dephasing superchannels. More precisely, we upper bound this number in terms of hypothesis testing channel divergence between E and its fully dephased version, and also relate it to the robustness of coherence of E.

This work aimed to investigate the steam oxidation resistance of additively manufactured Alloy 400 by the Laser Power Bed Fusion (LPBF) with different densities together with the hot extruded Alloy 400 at 650 – 750 oC for 500 h, EBSD/SEM/EDS analyses were carried out. The lowest mass gain was attributed to the hot extruded Alloy 400 at both temperatures. All the samples showed a high susceptibility to internal oxidation at 650 oC, at 750 °C a thick oxide scale rich in Cu and Ni was formed. The exposed samples showed no scale spallation and detachment of the oxide scale. © 2023, The Authors. All rights reserved.

The accurate simulation of additional interactions at the ATLAS experiment for the analysis of proton–proton collisions delivered by the Large Hadron Collider presents a significant challenge to the computing resources. During the LHC Run 2 (2015–2018), there were up to 70 inelastic interactions per bunch crossing, which need to be accounted for in Monte Carlo (MC) production. In this document, a new method to account for these additional interactions in the simulation chain is described. Instead of sampling the inelastic interactions and adding their energy deposits to a hard-scatter interaction one-by-one, the inelastic interactions are presampled, independent of the hard scatter, and stored as combined events. Consequently, for each hard-scatter interaction, only one such presampled event needs to be added as part of the simulation chain. For the Run 2 simulation chain, with an average of 35 interactions per bunch crossing, this new method provides a substantial reduction in MC production CPU needs of around 20%, while reproducing the properties of the reconstructed quantities relevant for physics analyses with good accuracy. © 2022, The Author(s).

A search for nonresonant Higgs boson pair production in the bb¯bb¯ final state is presented. The analysis uses 126 fb-1 of pp collision data at √s = 13 TeV collected with the ATLAS detector at the Large Hadron Collider, and targets both the gluon-gluon fusion and vector-boson fusion production modes. No evidence of the signal is found and the observed (expected) upper limit on the cross-section for nonresonant Higgs boson pair production is determined to be 5.4 (8.1) times the Standard Model predicted cross-section at 95% confidence level. Constraints are placed on modifiers to the HHH and HHVV couplings. The observed (expected) 2σ constraints on the HHH coupling modifier, κλ, are determined to be [-3.5, 11.3] ([-5.4, 11.4]), while the corresponding constraints for the HHVV coupling modifier, κ2V, are [-0.0, 2.1] ([-0.1, 2.1]). In addition, constraints on relevant coefficients are derived in the context of the Standard Model effective field theory and Higgs effective field theory, and upper limits on the HH production cross-section are placed in seven Higgs effective field theory benchmark scenarios. © 2023, CC BY.

Periodically driven quantum systems exhibit a diverse set of phenomena but are more challenging to simulate than their equilibrium counterparts. Here, we introduce the Quantum High-Frequency Floquet Simulation (QHiFFS) algorithm as a method to simulate fast-driven quantum systems on quantum hardware. Central to QHiFFS is the concept of a kick operator which transforms the system into a basis where the dynamics is governed by a time-independent effective Hamiltonian. This allows prior methods for time-independent simulation to be lifted to simulate Floquet systems. We use the periodically driven biaxial next-nearest neighbor Ising (BNNNI) model, a natural test bed for quantum frustrated magnetism and criticality, as a case study to illustrate our algorithm. We implemented a 20-qubit simulation of the driven two-dimensional BNNNI model on Quantinuum’s trapped ion quantum computer. Our error analysis shows that QHiFFS exhibits not only a cubic advantage in driving frequency ω but also a linear advantage in simulation time t compared to Trotterization. © 2023, CC BY-NC-ND.
