In the presence of global conservation laws holding on the joint meter-target system, the Wigner-Araki-Yanase theorem and its generalizations predict a lower bound on the measurement’s error (Ozawa’s bound). While practically negligible for macroscopic meters, it becomes relevant for microscopic ones. Here, we propose a simple interferometric setup, arguably within reach of present technology, in which a flying particle (a microscopic quantum meter) is used to measure a qubit by interacting with it in one arm of the interferometer. In this scenario, the globally conserved quantity is the total energy of particle and qubit. We show how the measurement error is linked to the nonstationary nature of the measured observable and the finite duration of the target-meter interaction while Ozawa’s bound only depends on the momentum uncertainty of the meter’s wave packet. When considering short wave packets with respect to the evolution time of the qubit, we show that is strictly tied to the position-momentum uncertainty of the meter’s wave packet and only when employing Gaussian wave packets. On the contrary, long wave packets of any shape lead to . In addition to their fundamental relevance, our findings have important practical consequences for optimal resource management in quantum technologies.","description":"A (target) quantum system is often measured through observations performed on a second (meter) system to which the target is coupled.

Conventional QCDSR analyses are based on assumptions such as quark-hadron duality and continuum models, which introduce a degree of systematic uncertainty. The inverse matrix method circumvents these assumptions by reformulating the problem as an inverse integral equation and expanding the unknown spectral density using orthogonal Laguerre polynomials. This method allows for a direct determination of spectral densities, thereby enhancing the precision of predictions regarding resonance masses and decay constants. By employing this methodology with regard to light-flavor diquarks ($sq$ and $ud$), it is possible to extract the associated masses and decay constants. The results indicate that the masses of diquarks with quantum numbers $J^P = 0^+$ and $J^P = 0^-$ are nearly degenerate.

When this system is expressed in terms of multiple components it can be used to explore the impact of a phase transition from a hadronic state to a quark plasma state with a complex clustering structure. The clustering can take the form of colored diquarks or triquarks and bound colorless meson, baryon, or hyperon states at the phase transition boundary. The resulting multicomponent EoS system is nonconvex which can give rise to nonclassical BZT phase changing shock waves. Using the BZT shock wave condition we find constraints on the quark density and examine how this changes the compactness and tidal deformability of the compact core. These results are then combined with the TOV equations to find the changes in the mass-radius relationship.

Our analysis is based on a hybrid equation of state with a phase transition from hypernuclear matter to color-superconducting quark matter, where both phases are described within a relativistic density functional approach. By varying the vector and diquark couplings of quark matter, we obtain different hybrid star sequences with varying extension of the quark matter core, ensuring consistency with astrophysical constraints from mass, radius and tidal deformability measurements. We demonstrate the impact of an increasing rotational frequency on the maximum gravitational mass, the central energy density of compact stars, the rise of the quasi-radial oscillations and non-axisymmetric instabilities. We demonstrate that for the most favorable parameter sets with a strong vector coupling, hybrid star configurations with color-superconducting quark matter core can describe the fastest spinning and heaviest galactic pulsar J0952-0607, while it is out of reach for the purely hadronic hypernuclear star configuration. We also revise the previously proposed empirical relation between the Kepler frequency, gravitational mass, and radius of non-rotating neutron stars, obtained based on the assumption that all neutron stars, up to the heaviest, are hadronic.

We directly relate the monodromy data of the radial Teukolsky equation to the parameter $\\\\nu$ and provide a numerical scheme for calculating $\\\\nu$ based on monodromy. With this method we evaluate $\\\\nu$ in different regions of parameter space and analyze the numerical stability of this approach. We also highlight how, through $\\\\nu$, monodromy data are linked to scattering amplitudes for generic (linear) perturbations of Kerr spacetime.","description":"The Teukolsky equation describes perturbations of Kerr spacetime and is central to the study of rotating black holes and gravitational waves.

The radio wave observation\'s 21-cm absorption signal can be explained as either anomalous baryon cooling or anomalous cosmic microwave background photon heating. Shortly after the axions or axion-like particles (ALPs) thermalize among themselves and form a Bose-Einstein condensate, the cold dark matter ALPs make thermal contact with baryons, cooling them. ALPs are thought to be the source of some new evidence for dark matter, as the baryon temperature at cosmic dawn was lower than predicted based on presumptions. The detection of baryon acoustic oscillations is found to be consistent with baryon cooling by dark matter ALPs. Simultaneously, under the influence of the primordial black hole and/or intergalactic magnetic fields, the dark radiation composed of ALPs can resonantly transform into photons, significantly heating up the radiation in the frequency range relevant to the 21-cm tests.

Furthermore, the underlying structure of known exotic states remains an unresolved fundamental issue in hadron physics, which is currently being addressed by hadron physics community. It is well known that electromagnetic characteristics can serve as a distinguishing feature for states whose internal structures are complex and not yet fully understood. The aim of this study is to determine the magnetic moments of vector hidden-charm tetraquark states by making use of QCD light-cone sum rules. In order to achieve this objective, the states mentioned above are considered in terms of the diquark-antidiquark structure. Subsequently, a comprehensive examination is conducted, with four distinct interpolating currents being given particular consideration, as these have the potential to couple with the aforementioned states. It has been observed that there are considerable discrepancies between the magnetic moment results extracted employing different diquark-antidiquark structures. Such a prediction may be interpreted as the possibility of more than one tetraquark with the identical quantum numbers and similar quark constituents, but with different magnetic moments. The numerical predictions yielded have led to the conclusion that the magnetic moments of the vector hidden-charm tetraquark states are capable of projecting the inner structure of these states, which may then be used to determine their quark-gluon structure and quantum numbers.

And what advantages does quantum computing offer to the advancement of nanotechnology? Therefore, this work analyzes how the advance of quantum computing has been influenced by nanotechnology and vice versa, and how quantum computing affects nanotechnology itself. In this way, this article clarifies the paths at which nanotechnology and quantum computing are connected on the route to future technologies in society. In conclusion, we found out that nanotechnology is crucial for the advancement of QC due to the quantumness stands in the nanometric size and the QC-based industry relies on the solid physics state nanoassembly, while on the other hand, QC significantly increases the performance of nanotransistors, imprint better sensibility features on nanosensors, among other things.","description":"The review of progress in quantum computing (QC) is very pertinent nowadays.
