- Abstract: Processing quantum information using quantum three-level systems or qutrits
as the fundamental unit is an alternative to contemporary qubit-based
architectures with the potential to provide significant computational
advantages. We demonstrate a fully programmable two-qutrit quantum processor by
utilizing the third energy eigenstates of two transmons. We develop a
parametric coupler to achieve excellent connectivity in the nine-dimensional
Hilbert space enabling efficient implementations of two-qutrit gates. We
characterize our processor by realizing several algorithms like Deutsch-Jozsa,
Bernstein-Vazirani, and Grover's search. Our efficient ancilla-free protocols
allow us to show that two stages of Grover's amplification can improve the
success rates of an unstructured search with quantum advantage. Our results
pave the way for building fully programmable ternary quantum processors using
transmons as building blocks for a universal quantum computer.
