Transmitting qudits through larger quantum channels
By a quantum channel is intended [1, 2] a completely positive and trace-precerving linear map Φ : σ(H) → σ(H), where σ(H) is a set of states in a Hilbert space H with dimH = n ≤ +∞. Even for a finite dimension n < +∞ there is a number of difficult problems concerning the construction of optimal transmission of the information through a quantum channel. The infinite dimensional case we are espec...
متن کاملLandau–Zener transitions in qubits controlled by electromagnetic fields
We investigate the influence of a dipole interaction with a classical radiation field on a qubit during a continuous change of a control parameter. In particular, we explore the non-adiabatic transitions that occur when the qubit is swept with linear speed through resonances with the time-dependent interaction. Two classic problems come together in this model: the Landau– Zener (LZ) and the Rab...
متن کاملHigher Spin Hadrons as Relativistic Fields *
I discuss the problem of consistent interactions of higher-spin fields and its relevance to resonance physics.
متن کاملOn the Relativistic Transformation of Electromagnetic Fields
a By investigating the motion of a point charge in an electro-static and in a magnetostatic field, it is shown that the rel-ativistic transformation of electromagnetic fields leads to ambiguous results. The necessity for developing an 'elec-trodynamics for moving matter' is emphasized. Classical electrodynamics, as it is taught today [1], is based on Hertz's formulation [2] of Maxwell's field e...
متن کاملNonequilibrium Dynamics of Relativistic Quantum Fields
The understanding of quantal many-body systems is a challenging task for far-from-equilibrium conditions as appearing in high energy heavy-ion collisions or cosmological problems. It is of relevance to describe ab-initio thermalization by taking into account all quantum aspects of the particles rather than invoking semi-classical approximation schemes from the beginning [1, 2]. We here consider...
