Quantum mechanics over real numbers fully reproduces standard quantum theory
Alan C. Maioli, Evaldo M. F. Curado, Jean-Pierre Gazeau
Standard quantum mechanics employs complex Hilbert spaces, but whether complex numbers are fundamental or merely convenient has long been debated. For decades, real-valued equivale…

The Geometry of Qubit Decoherence: Linear vs. Nonlinear Dynamics in the Bloch Ball
Alan C. Maioli, Evaldo M. F. Curado, Jean-Pierre Gazeau +1
We present two complementary approaches to the GKSL equation for an open qubit. The first, based on linearity, yields solutions illustrated by mixed states trajectories in the Bloc…
