Simulating single-spin dynamics on an IBM five-qubit chip
In this paper we show how the IBM superconducting chips can be a powerful
tool for teaching foundations of quantum mechanics for undergraduate students
(for graduates as well, in some cases). To this end, we briefly discuss about
the main elements of the IBM Quantum Experience platform necessary to
understand this paper, i.e., how to implement operations and single-qubit
measurements. We experimentally study the dynamics of single spin systems
interacting with static and time-dependent magnetic fields. First, we study the
resonant behavior of a single spin coupled to a time-dependent rotating
magnetic field. To end, we study the Larmor precession phenomenon. In both
cases we show the theoretical and real experimental implementation. This
article could be useful in introductory courses on quantum mechanics and
nuclear magnetic resonance foundations, for example.
