Reduced fidelity in topological quantum phase transitions
... to a TQPT, which involves a global rearrangement of nonlocal quantum correlations 关1兴. However, this intuition turns out to be wrong. As we show in this Rapid Communication, several TQPTs are accurately signaled by a singularity in the second-order derivative of the reduced fidelity. Moreover, the s ...

Quantum Mechanics Made Simple: Lecture Notes
... The latest twist to the interpretation in quantum mechanics is the parallel universe view that explains the multitude of outcomes of the prediction of quantum mechanics. All outcomes are possible, but with each outcome occurring in different universes that exist in parallel with respect to each othe ...

... Figure 5. The ground-state configurations of various multielectron atoms, calculated using a Bohr-like model. For both the n = 1 and n = 2 shells, the electron locations (red dots) found from that simplistic model agree closely with the maximum charge densities obtained from standard quantum-theory ...

We are now ready to leave the playpen, and see how randomness fits into the structure of physics at the most funda ...

The most common choice is a two-dimensional (or, in case of spherical quantum dots, three-dimensional) harmonic oscillator potential, since the solutions for the one-particle p ...

... The typical classical single-bit error is the bit-flip: 0 ↔ 1. If we assume a simple error model (the binary symmetric channel) in which bit flips errors occur on each bit independently with probablility p per unit time, we expect a bit to be corrupted after O(1/p) steps. (In general, we assume p ≪ ...
