Query: Fast computation of spherical phase-space functions of quantum many-body
  states   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 phase spaces for finite-dimensional quantum states of single qudits
or permutationally symmetric states of multiple qubits. We present methods to
efficiently compute the corresponding 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 these phase-space techniques.
