Although claimed for a many electron system, some of the (nonradiative and nonretarded) QED energy expressions (i.e., Eqs. (92), (95), and (107)) in Ref.1 are found to hold only for the special case of two electrons. In particular, except for the diagrams considered before (see Figs. (3a) to (3h)), the socalled three-electron-two-photon diagram2 shown in Fig. (3i) should also be included for th...

Computational Approaches of Relativistic Models in Quantum Chemistry

This chapter is a review of some methods used for the computation of relativistic atomic and molecular models based on the Dirac equation. In the linear case, we brieey describe nite basis set approaches, including ones that are generated numerically , perturbation theory and eeective Hamiltonians procedures, direct variational methods based on nonlinear transformations, min-max formulations an...

Relativistic quantum coin tossing

A relativistic quantum information exchange protocol is proposed allowing two distant users to realize “coin tossing” procedure. The protocol is based on the point that in relativistic quantum theory reliable distinguishing between the two orthogonal states generally requires a finite time depending on the structure of these states. PACS numbers: 03.67.-a, 03.65.Bz, 42.50Dv The coin tossing pro...

Relativistic Quantum Bit Commitment

A new relativistic quantum protocol is proposed allowing to implement the bit commitment scheme. The protocol is based on the idea that in the relativistic case the field propagation to the region of space accessible to measurement requires, contrary to the non-relativistic case, a finite non-zero time which depends on the structure of the particular state of the field. In principle, the secret...
