Spacetime-matter entanglementInformation completenessQuantum entanglement dynamicsTrinityIt was known long ago that quantum theory and general relativity, two pillars of modern physics, are in sharp conflict in their foundations. Their fundamental inconsistencies render a consistent theory of quantum gravity ...
Oxford physicist and mathematician Roger Penrose says that space and time themselves are secondary constructs that emerge out of a deeper level of reality. Both Quantum physics, where the future is unknown, andrecent experiments verifying quantum entanglement, where particles instantaneously communicate ove...
[offtopic] 啱啱過咗嘅星期日舉行咗特首選舉,對於有好多市民擁護嘅薯片輸咗,好多人包括泛民好失望,我淨係想講democracy is never about electing the most popular candidate/policy; it is about the system behind *量子力學入面有樣嘢叫量子糾纏(quantum entanglement),就咁睇好似同相對論講冇嘢包括訊息嘅傳遞可...
Quantum entanglementCosmic string spacetimeMassless scalar fieldWe examine the entanglement behaviors for two static atoms coupled to a massless scalar field in the cosmic string spacetime. The entanglement measure is calculated for different cases for two atoms initially prepared in the Werner state. It...
The original thought was that quantum entanglement—which links particles no matter how far they are separated—was the most important factor: the more entangled particles on the boundary are, the smoother the spacetime within the bulk. “But just considering the degree of entanglement on the bo...
In the fully Lorentzian case, it would be interesting to determine whether this only reproduces the extremal surface at the edge of the entanglement wedge, or also its null boundaries. At least extremal area surfaces are expected to play a role of special importance in quantum gravity for ...
But at a basic level, the idea was to prove that a quantum theory could entirely describe spacetime, which would mean that spacetime comes from some aspect (or aspects) of the quantum world. For a while, physicists toyed with the idea that the aspect in question was quantum entanglement—...
frequency regime owing to dispersion, it is well known that the curved spacetime phenomenology persists for these excitations24,26,35. Altogether, the above properties suggest that an extensive draining vortex of He II is a feasible candidate for simulations of a quantum field theory in curved ...
