AbstractIn this paper we re-investigate the core of Schrödinger’s “cat paradox”. We argue that one has to distinguish clearly between superpositions of macroscopic cat states |☺〉 + |☹〉 and superpositions of entangled states |☺, ↑〉 + |☹, ↓〉 which comprise both the state of the cat (☺=alive, ☹=dead) and the radioactive substance (↑=not decayed, ↓=decayed). It is shown, that in the case of the cat experiment recourse to decoherence or other mechanisms is not necessary in order to explain the absence of macroscopic superpositions. Additionally, we present modified versions of two quantum optical experiments as experimenta crucis. Applied rigorously, quantum mechanical formalism reduces the problem to a mere pseudo-paradox.

Quantum Mechanical Formalism

We develop a generalized quantum mechanical formalism based on the nilpotent commuting variables (η-variables). In the nonrelativistic case such formalism provides natural realization of a two-level system (qubit). Using the space of η-wavefunctions, η-Hilbert space and generalized Schrödinger equation we study properties of pure multiqubit systems and also properties of some composed, hybrid models: fermion–qubit, boson–qubit. The fermion–qubit system can be truly supersymmetric, with both SUSY partners having identical spectra. It is a novel feature that SUSY transformations relate here only nilpotent object. The η-eigenfunctions of the Hamiltonian for the qubit–qubit system give the set of Bloch vectors as a natural basis.

Mott Scattering

SynopsisIt is shown that, from an operational point of view, the production and detection of spin-polarised electrons by Mott scattering is equivalent to the performance of a Stern-Gerlach type experiment with heavy spin-one-half particles. The argument is based on standard quantum mechanical formalism using density matrices and Stokes vectors for the description of polarised assemblies of particles.

Quantum Mechanical Formalism

We calculate the broadening and shift of two lines (4121 Å and 4437 Å) for neutral helium in a plasma. To obtain the effect of the electron collisions the quantum-mechanical formalism developed by Bassalo and Cattani is used. Our theoretical predictions are compared with the experimental results of Wulff and of Bötticher, Roder, and Wobig and with the semi-classical estimates of Griem, Baranger, Kolb, and Oertel.

Quantum Mechanical Formalism

In this paper we apply the quantum mechanical formalism developed by Bassalo and Cattani to calculate the broadening and shift produced by electronic collisions of the43s → 23p line of helium in a plasma. The effect of the ions is also taken into account. Our theoretical predictions are compared with the experimental results of Bötticher et al. and with the semiclassical estimates of Griem et al.
