      abstract     = {Quantum devices are preparing increasingly more complex
                      entangled quantum states. How can one effectively study
                      these states in light of their increasing dimensions? Phase
                      spaces such as Wigner functions provide a suitable
                      framework. We focus on spherical phase spaces for
                      finite-dimensional quantum states of single qudits or
                      permutationally symmetric states of multiple qubits. We
                      present methods to efficiently compute the correspond- ing
                      spherical phase-space functions which are at least an order
                      of magnitude faster than traditional methods. Quantum
                      many-body states in much larger dimensions can now be
                      effectively studied by experimentalists and theorists using
                      spherical phase-space techniques.},
