... • A classical wave also spreads out. The more localized the region in which the wave is confined, the more the wave spreads out in time. • Why isn’t that called an “uncertainty principle” and given philosophical hype? • Because nothing is really “uncertain”: the wave is definitely spread out. If you ...

What is quantum communication?
... essential for future applications such as quantum key distribution and quantum networks. The direct distribution of quantum states is limited by unavoidable transmission losses of the channel used to transmit these quantum states. The direct approaches are limited to much less than 500 km, even unde ...

... quasiparticles are quantum superpositions of particle and hole ⇒ do not correspond to definite particle number (justified by appeal to SBU(1)S). This “particle‐hole mixing” is sometimes (misleadingly) regarded as analogous to the mixing of different bands in an insulator by spin‐orbit coupling ...

... The theory of quantum mechanics was developed by Erwin Schrödinger, Werner. According to quantum mechanics, the position and momentum of a particle cannot both be accurately known at the same time. Only its most probable position or momentum can be determined. The most probable distance between the ...

The unique EPR correlation of (x1 - x2) & (p1 + p2) made entangled state very special: the pair comes out from a point on the object plane, under goes two-photon diffraction, and stops at a point on the image plane. The twophoton diffraction provide us sub-wavelength spatial resolution (/). “Is ...
