- Abstract: We develop a formalism for the robust dynamical decoupling and Hamiltonian
engineering of strongly interacting qudit systems. Specifically, we present a
geometric formalism that significantly simplifies qudit pulse sequence design,
while incorporating the necessary robustness conditions. We experimentally
demonstrate these techniques in a strongly-interacting, disordered ensemble of
spin-1 nitrogen-vacancy centers, achieving over an order of magnitude
improvement in coherence time over existing pulse sequences. We further
describe how our techniques enable the engineering of exotic many-body
phenomena such as quantum many-body scars, and allow enhanced sensitivities for
quantum metrology. These results enable the engineering of a whole new class of
complex qudit Hamiltonians, with wide-reaching applications in dynamical
decoupling, many-body physics and quantum metrology.

We use a generalization of the Majorana representation for Hamiltonians to develop a simple framework that establishes the decoupling properties of each Platonic sequence.
These sequences are universal in their ability to cancel any type of interaction with the environment for single qudits with up to 6 levels.
They are capable of decoupling up to 5-body interactions in an ensemble of interacting qubits with only global pulses.

We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide.

We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

Unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (non-unitary) dynamics.
We introduce a method to deal with these systems based on the calculation of (dissipative) lattice Green's function.
We illustrate the power of this method with several examples of driven-dissipative bosonic chains of increasing complexity.
