QuoteSome relationships end loudly, most end quietly. There is no dramatic fight or sudden revelation. Instead, partners gradually stop showing up for each other in small, everyday ways.

The legal divorce, if it comes at all, is simply the final step in a separation that happened long before. "Quiet divorcing," the term given to this slow, mostly invisible retreat from a long-term relationship, has recently gone viral.

Borrowing from the term "quiet quitting," it has caught fire because it names an experience many people recognize but rarely articulate.

QuoteQuantum communication follows a similar idea, but individual photons act as the information carriers. A zero or one is encoded through the direction of the photon's polarization (i.e., their orientation in the horizontal and vertical directions or in a superposition of both states). Because photons behave according to quantum mechanics, their polarization cannot be measured without leaving detectable traces. Any attempt to intercept the message would be exposed.

Teleportation requires the photons to be nearly identical in properties such as timing and color. Producing such photons is hard because they come from separate sources.

At the University of Stuttgart, the researchers successfully teleported the polarization state of a photon from one quantum dot to a photon produced by a second quantum dot. One dot emits a single photon and the other generates an entangled photon pair. "Entangled" means the two photons share a single quantum state even when physically apart. One photon from the pair travels to the second quantum dot and interacts with its photon. When the two overlap, their superposition transfers the information from the original photon to the far-away partner of the entangled pair.

A key element of this achievement was the use of "quantum frequency converters," devices that adjust small frequency mismatches between photons.

QuoteWild chimpanzees have been found to consume the equivalent of a bottle of lager's alcohol a day from eating ripened fruit, scientists say.

They say this is evidence humans may have got our taste for alcohol from common primate ancestors who relied on fermented fruit - a source of sugar and alcohol - for food.

QuoteIn a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at extremely low temperatures, just like ordinary quantum systems. The finding provides strong evidence that black holes possess isolated ground states, a hallmark of quantum mechanical behavior.

Prior calculations showed that black hole entropy might become negative at low temperatures, a result that appeared physically puzzling. In this work, researchers addressed the paradox by incorporating wormhole effects in the two-dimensional Jackiw-Teitelboim (JT) gravity model.

In quantum systems, entropy measures the number of possible microscopic configurations. If a system has an isolated ground state—a unique lowest energy configuration—its entropy should vanish as temperature approaches absolute zero.

QuoteHydrodynamics theory offers quantum physicists with an alternative route for simulating the interactions between particles in large systems. If a system is chaotic, in fact, researchers can assume that the particles will interact in ways that will ensure a state of local thermal equilibrium.

"Quantum systems are fundamentally different from their classical counterparts because their constituent particles can exhibit quantum phenomena like entanglement, which defy everyday intuition," said Wienand. "They are also much harder to calculate, so being able to describe them using FHD could help us understand such systems better and make predictions about them."

QuoteOn the other hand, studying the dynamics of individual microscopic degrees of freedom comprehensively becomes too cumbersome even when considering systems of a moderate number of particles. To describe the interface between these opposite ends of the scale, stochastic field theories are commonly used to characterize the dynamics of complex systems and the effect of the microscopic fluctuations.
