Dice Cubes: Quantum-Based Networked Performance with CubeHarmonic

This paper explores the intersection of quantum computing and the Internet of Musical Things, a topic that hitherto has received little attention from scholars. The CubeHarmonic (CH) is a musical instrument based on the Rubik's cube. Here, we consider the case of three remote performers of CH that exchange over the network minimal information, as a string of probability amplitudes of performing specific rotations. The state of possible rotations are modeled as quantum states, and the actual decided moves as results of a quantum measurement. We propose a quantum circuit to help maximize the musical variety that can be obtained by three remote CH performers.
