Journal of Physics A: Mathematical and Theoretical, 2012 To visualize a higher dimensional object it is convenient to consider its two-dimensional cross-sections. The set of quantum states for a three level system has eight dimensions. We supplement a recent paper by Goyal et al by considering the set of all possible two-dimensional cross-sections of the qutrit.

Stationary Phase Method in Discrete Wigner Functions and Classical Simulation of Quantum Circuits [PDF]
Quantum, 2021 One of the lowest-order corrections to Gaussian quantum mechanics in infinite-dimensional Hilbert spaces are Airy functions: a uniformization of the stationary phase method applied in the path integral perspective.

Laser Physics, 2007 For two types of qutrits specified by the dynamical symmetry SU(3) and SU(2), we consider the difference in entanglement caused by the lack of quantum observables in the latter case. In particular, we show that the SU(2) qutrits can have specific separable entanglement caused by quantum correlations of intrinsic degrees of freedom in a single party ...

Fast and simple scheme for generating NOON states of photons in circuit QED [PDF]
, 2014 The generation, manipulation and fundamental understanding of entanglement lies at very heart of quantum mechanics. Among various types of entangled states, the NOON states are a kind of special quantum entangled states with two orthogonal component ...
