Quantum error-correcting codes from algebraic curves
... this may not be the most concise expression for a quantum code (see Gottesman’s thesis [13] for some examples illustrating this). In fact, for a large class of quantum codes called stabilizer codes, another algebraic structure is more useful. Stabilizer codes over F2 were introduced by Gottesman in ...

... Since all classical quantities can be represented by real numbers, which of course satisfy a commutative rule of multiplication, this property looks very strange. Paul Dirac introduced the felicitous names of c–numbers and q– numbers, the former standing for classical numbers, the latter for quantum ...

Creation of entangled states in coupled quantum dots via adiabatic... C. Creatore, R. T. Brierley, R. T. Phillips,
... ARP, then, allows a pulse to be constructed that transfers these pairs into their entangled excited states, without exciting the others. Thus, as shown in Fig. 3, the entanglement of formation per excitation could be very close to one, even within a strongly disordered ensemble. Our approach represe ...

Remarkably, if perfect cloning was permitted, the Heisenberg uncertainty principle could be violated by measuring conjugate observables on many copies of a single quantum system. Consider a cloning machine that duplicates a quantum bit (a 2-state s ...

Quantum Channels - Institut Camille Jordan
... Let us recall the setup of quantum open systems. We are given two quantum systems interacting together, with state space H and K respectively. Our approach is in discrete time only in this section, that is, we shall look at the evolution of the two systems together for a fixed time duration τ . This ...

An Historical and Modern View on Bell`s Inequality
... The realist position is that the particle was at x0 (it should be noted that if this were the case quantum mechanics would be an incomplete theory). The orthodox position is that the particle wasn’t really anywhere. One can also refuse to answer, saying that the question is a metaphysical one; this ...
