  Previous theoretical and experimental research has shown that current NISQ
devices constitute powerful platforms for analogue quantum simulation. With the
exquisite level of control offered by state-of-the-art quantum computers, we
show that one can go further and implement a wide class of Floquet
Hamiltonians, or timedependent Hamiltonians in general. We then implement a
single-qubit version of these models in the IBM Quantum Experience and
experimentally realize a temporal version of the Bernevig-Hughes-Zhang Chern
insulator. From our data we can infer the presence of a topological transition,
thus realizing an earlier proposal of topological frequency conversion by
Martin, Refael, and Halperin. Our study highlights promises and limitations
when studying many-body systems through multi-frequency driving of quantum
computers.
