Their verdict is clear: no classical macroscopic theory can truly describe reality. The work also provides further proof that a particle can be in a superposition of two states associated with different locations – even when these locations are centimetres apart. Correlation strengths The LGI is ...
Scientists at the MPL have now indicated a particularly efficient way in which photons can be entangled with acoustic phonons: While the two quanta travel along the same photonic structures, the phonons move at a much slower speed. The underlying effect is the optical nonlinear effect known as B...
which is a first for X-ray energies. The next steps planned by the team include on-demand release of the stored photon wave packets, which could lead to the realization of the entanglement between different hard X-ray photons —
Causality is key to our experience of reality: dropping a glass, for example,causesit to smash, so it can’t smash before it’s dropped. But in the quantum world those rules don’t necessarily apply, and scientists have now demonstrated how that weirdness can be harnessed to charge a quan...
The laser trick that could put an ultraprecise optical clock on a chip Researchers have made a key breakthrough in how light is used to control time signals from the world’s most precise clocks. The technique marks a crucial step in bringing this technology into everyday life. Mengxi Tan...
This is a reality constructed with the help of theoretic concepts; it is not something that you may simply “observe.” Xenophanes (ca. 500 BC) already pointed out similar ideas (Wikipedia). The concept of quantum state is central to the quantum-physical view. Basically, there is no need ...
methods has been used against them. Bad actors could secretly steal sensitive data without its owners knowing. That unpleasant reality has moved so-calledpost-quantum cryptographyto the top of many organizations' plans for quantum computing. Many are developing or looking to buyquantum-resistant ...
Gravitational waves carry information about far away phenomena which astronomers can use to form a better picture of the universe. Over the past few years,
Bear in mind that electrons are among the commonest and most basic building blocks of reality and yet here's Bohr saying that only by looking,do we actually conjure their position into existence.我们与量子世界之间似乎隔着一道帷幕,而在帷幕的后面,没有确定的实在,只有可能的实在。事情只有在我们拉...
By using pure gravity rather than exotic matter, their new model challenges previous theories and brings us closer to understanding the true nature of spacetime. This breakthrough not only simplifies the conditions forblack holeformation but also aligns with the fundamental laws of thermodynamics. Th...
