Entanglement in single-particle systems
... to call these the electronic states of the atom. Consequently, the groundstate of a hydrogen atom is a tensor product of the groundstate of the free centre of mass (i.e. a plane wave of zero momentum) and the groundstate of the relative particle (i.e. the spherical 1s orbital). There is no entanglem ...

Quantum networks in the presence of D B
... We now concentrate on a periodic tiling with the hexagonal symmetry, called T3 (Fig 5a). This is a periodic hexagonal structure with three sites per a unit cell, one sixfold coordinated and two threefold coordinated. It is also an example of a twodimensional regular bipartite lattice containing node ...

Quantum error-correcting codes from algebraic curves
... We next discuss how quantum codes guard against errors. Unlike the classical case, it is not immediately obvious that this is even possible. More pointedly, classical codes protect information by adding redundancy with ...

Quantum phenomena in gravitational field - AEgIS

The experiments with antiatoms (see [8,9] and references therein) are even more interesting in view of testing WEP, because the theories striving to unify gravity and quantum mechanics (such as super-symmetric string theories) tend to sug ...

How to Construct Quantum Random Functions
... Goldreich, Goldwasser, and Micali show how to build a pseudorandom function PRF from any length-doubling pseudorandom generator G. This construction is known as the GGM construction. Pseudorandom generators can, in turn, be built from any one-way function, as shown by Håstad et al. [HILL99]. The se ...

Chapter 4 The Two Slit Experiment
... we have to expect that P12 (x) = P1 (x) + P2 (x), but this not what is observed. It appears that we must abandon the idea that the particles go through one slit or the other. But if we want to retain the mental picture of electrons as particles, we must conclude that the electrons pass through both ...

6 Product Operators

This operator is exceptionally important as its eigenvalues and eigenfunctions are the "energy levels" of the system, and it is transitions between these energy levels which are detected in spectroscopy. To u ...

Quantum Measurement and Control
... We now consider measurement of a classical system. With a perfect measurement of X, the observer would simply find out its value, say x . The system state would then be a state of complete knowledge about this variable. For discrete variables this is represented by the Kronecker δ-function ℘(x) = ...
