When we are beginning a new project, we will need to create a new memory. You can also import memories that clients or other translators provide. Even if you already have a TM of your own you should always ask
The interactive look and feel of a corporate website could help shape positive perceptions about the organization if the site includes a likable design and features that engage the target audience, especially job seekers, according to Penn State media researchers.
We pose the fundamental question of communication properties of primitivesirrespectively of their implementation. To illustrate the idea we introduce theconcept of entanglement-swapping boxes, i.e. we consider any quantum operationswhich perform entanglement swapping, not necessarily via simple quantumteleportation. We ask a
The original Schrodinger's paper is translated and annotated in honour of the70-th anniversary of his Uncertainty Relation [published also in: Bulg. Journalof Physics,vol.26,no.5/6 (1999) pp.193-203]. In the annotation it is shown thatthe Uncertainty Relation can be written in a complete
Superconducting qubits behave as artificial two-level atoms and are used toinvestigate fundamental quantum phenomena. In this context, the study ofmulti-photon excitations occupies a central role. Moreover, couplingsuperconducting qubits to on-chip microwave resonators has given rise to thefield of circuit QED.
We explicitly construct the states that are invariant under the action of thegeneralized squeezing operator $\exp{(z{a^{\dagger}}^k-z^*a^k)}$ with integer$k \geq 3$. There are $k$ such states for a given value of $k$. We show that inthe number representation the states behave
The optimal $N$ qubit states featuring highest sensitivity to smallmisalignment of cartesian reference frames are found using the QuantumCram\'{e}r-Rao bound. It is shown that the optimal states are supported on thesymmetric subspace and hence are mathematically equivalent to a single
The optical quantum computer is one of the few experimental systems to havedemonstrated small scale quantum information processing. Making use of cavityquantum electrodynamics approaches to operator measurements, we detail anoptical network for the deterministic preparation of arbitrarily largetwo-dimensional cluster states.
We propose a new model for description of electrons beam dynamics in FreeElectron Laser (FEL) undulator, based on the method of linear time-dependentinvariants of quantum-mechanical charge particle. The magnetic field hasperiodic structure along the undulator. For this problem, described bytime-dependent
Entanglement of multipartite systems is studied based on exchange symmetryunder the permutation group S_N. It is shown that anti-symmetric (fermionic)states are necessarily globally entangled, while symmetric (bosonic) states areeither globally entangled or fully separable and possess essentially identicalstates in all
We report on a complete free-space field implementation of a modified Ekert91protocol for quantum key distribution using entangled photon pairs. For eachphoton pair we perform a random choice between key generation and a Bellinequality. The amount of violation is used
We study the possibility of testing local realistic theory (LRT), envisionedimplicitly by Einstein, Podolsky and Rosen in 1935, based on the Bellinequality for the correlations in the decay modes of entangled K or B-mesons.It is shown that such a test
The Affleck-Kennedy-Lieb-Tasaki (AKLT) spin interacting model can be definedon an arbitrary graph. We explain the construction of the AKLT Hamiltonian.Given certain conditions, the ground state is unique and known as theValence-Bond-Solid (VBS) state. It can be used in measurement-based quantumcomputation
In a previous paper, we showed that many important quantuminformation-theoretic phenomena, including the no-cloning and no-broadcastingtheorems, are in fact generic in all non-classical probabilistic theories. Anexception is teleportation, which most such theories do not support. In thispaper, we investigate which
We explore and develop the mathematics of the two multi-level ions. Inparticular, we describe some new features of quantum entanglement in twothree-level trapped ions confined in a one-dimensional harmonic potential,allowing the instantaneous position of the center-of-mass motion of the ions
Report Buyer, the online destination for business intelligence for major industry sectors, has added a new report showing that the global sales of food additives were estimated at well in excess of $25billion in value terms during 2007.
