The article talks about the importance of quantum coherence in the development of quantum computers. Quantum coherence allows qubits to maintain their quantum state for longer periods of time, resulting in increased processing capacity and more complex calculations. Researchers from China and Israel propose that the increase in kinetic inductance in superconducting circuits is due to quantum interference effects induced by impurities in the material. On the other hand, researchers from the University of Seville and the University of Bristol have discovered a mechanism that explains the periodic movement of air bubbles in water, a phenomenon mentioned by Leonardo da Vinci in the 15th century.

In this work, a two-level quantum dot inside of a cavity with a non-linear Kerr-type medium and a single mode of the electromagnetic field quantized was considered. The master equation was constructed taking into account dissipative processes, with the non-linear Kerr term, and it was numerically solved for the stationary state, taking into account the temperature. On the basis of these results, observable aspects of the state of the light were calculated, such as the average number of photons and the spectrum of photoluminescence, and the quantum-classical characteristics of the state of the light were determined by means of the calculation of the coherence functions of the second-order photons.

The article titled "Verifying Quantum Mechanics at the Energy Frontier" highlights the importance of continuing to test the validity of quantum mechanics at increasingly higher energy scales. It is mentioned that one of the most characteristic predictions of quantum mechanics is entanglement, a phenomenon in which two or more particles lose their independence and can only be described as an interdependent whole. So far, the entanglement between elementary particles with three possible spin states, called qutrits, has not been experimentally measured. However, it is estimated that existing data from the Large Hadron Collider (LHC) would allow for the experimental establishment of entanglement between elementary qutrits. Additionally, the article mentions that quantum coherence, the ability to maintain superposition and quantum interference in a system, is crucial for the development of quantum computers. A longer coherence time implies greater scalability and processing capacity, as well as a reduction in calculation errors. Therefore, increasing quantum coherence time is crucial for the advancement of quantum computing and its adoption in various industrial and scientific applications. [Extracted from the article]
