Introduction to loop quantum gravity
... The quantum nature of three of the four forces, electromagnetism, weak and strong interactions, suggest that gravitational force too should have quantum properties at Planck scales. Loop quantum gravity (LQG) is an attempt to quantise gravity in a non-perturbative and background independent way. Thi ...

Quantum Picture of the Josephson Junction
... Unlike the Harmonic Oscillator Potential, the energy spaces of the wash board potential are not equal. This is a significant quality of this system that makes it a candidate for qubit, as discussed later. The potential in my calculation and the eigenfunctions for the 4 lowest states are shown in Fig ...

Determinant formulas for the reflection equation algebra
... The twist procedure outlined in the previous section induces an isomorphism of centers, so that the center of the REA of rank N is generated also by N elements, p̃1 , . . . , p̃N , which are (different, ad-invariant) quantum analogs of the above coefficients. In particular, p̃1 will be a quantum ana ...

Kochen-Specker Theorem and Games
... One of the statements one would hear pretty early in any quantum mechanics course is that for quantum particles there are properties which do not have definite values. For example, if we measure |+i in standard basis, the best we can do to describe the outcome is to say, that with probability 1/2 we ...

Average-Case Quantum Query Complexity
... biggest gap known between quantum and classical worst-case complexities for total functions. (In contrast, for partial Boolean functions the gap can be much bigger [9, 18].) A recent result is that the gap between D(f ) and Q(f ) is at most polynomial for every total f : D(f ) 2 O(Q(f )6 ) [3]. This ...

Time dilation: Lorentz contraction
... Alice sees the same events from the speeding train. By the time the light has travelled 10 km, Alice moved a bit towards B and the light of B reaches her before A. Since also for Alice, the speed of light from AD is the same as that of BD she will conclude that strike B happened before strike A. Now ...

Weak value amplification: a view from quantum estimation theory
... Weak value amplification (WVA)1 is a concept that has been used under a great variety of experimental conditions2–8 to reveal tiny changes of a variable of interest. In all those cases, a priori sensitivity limits were not due to the quantum nature of the light used (photon statistics), but instead ...
