Quantum error correction is usually implemented via an active schedule of discrete error syndrome
measurements and adaptive recovery operations which are hardware intensive and prone to
introducing and propagating errors.  In this talk, we will discuss our recent series of experiments
tailoring continuous dissipative processes in superconducting circuit QED to implement autonomous
error correction for qubits encoded in bosonic cavity states. We will focus on two generations of

The nitrogen vacancy (NV) center in diamond exhibits spin-dependent fluorescence and long spin
coherence times under ambient conditions, enabling applications in quantum information processing and
sensing. NV centers near the surface can have strong interactions with external materials and spins, enabling
new forms of nanoscale spectroscopy. However, NV spin coherence degrades within 100 nanometers of the
surface, suggesting that diamond surfaces are plagued with ubiquitous defects. I will describe our recent

I will describe our theory research towards harnessing ultracold matter by programming the systems' behavior in both real space and "synthetic" space. 

For the past two decades harmonically trapped ultracold atomic gases have been used with
great success to study fundamental many-body physics in flexible experimental settings.
However, the resulting gas density inhomogeneity in those traps has made it challenging to
study paradigmatic uniform-system physics (such as critical behavior near phase transitions) or
complex quantum dynamics. The realization of homogeneous quantum gases trapped in optical
boxes has been a milestone in quantum simulation [1]. These textbook systems have proved to
