Quantum tunneling is a quantum mechanical effect in which particles have a finite probability of crossing an energy barrier, such as the energy needed to break a bond with another particle, even when that quantum particle’s energy is less than the energy barrier. Because matter is both particle...
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。事情只有在我们拉开...
a quantum effect so unintuitive that einstein dubbed it “spooky action at a distance.” when two qubits in a superposition are entangled, certain operations on one have instant effects on the other, a process that helps quantum algorithms be more powerful than conventional ones. what's ...
Thus, a kind of historical background of the recent ontic breakthrough is given. The brealthrough itself is presented in Part II.doi:10.48550/arXiv.1409.3851Fedor HerbutEprint ArxivF. Herbut, "On Historical Background to the Ontic Breakthrough.I Polemic Defense of Quantum Reality", arXiv:...
Regardless, he notes that working at a single-photon level without losing information qualifies the nuclear frequency comb protocol as a quantum memory, 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 ...
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 ...

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...
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...
