Coherent control of motional quanta for a 3-qubit encoding in neutral 171Yb

In this presentation you will see an architecture for encoding three qubits within the optical "clock" transition, nuclear spin, and motional degrees of freedom of ytterbium-171 atoms in optical tweezers. This architecture extends the two-qubit "ququart" encoding from previous work to give greater hardware efficiency for the purposes of quantum computation and simulation. We present a set of native implementations of several one-, two-, and three-qubit gates that can be performed within the "quoct" space of a single atom, three- and four-qubit Rydberg gates between atoms, and a state measurement protocol leveraging coherent control of motional quanta both inside and outside the computational basis. We demonstrate the advantages of this encoding with an implementation of a quantum chromodynamics simulation in 1+1D for a single flavor of quark in the axial gauge.
