(SG) phase in a quantum optical system. Spin glasses underpin a wide array of
complex topics, including neural networks and combinatorial optimization. A
network of N=8 ultracold gases with pseudospin degrees of freedom are placed
inside a confocal cavity, which mediates controllable sign-changing interactions
between the 8 network nodes. The network evolves into an ordered phase as the
atoms are pumped through a super-radiant phase transition. We holographically
reconstruct the cavity emission to measure the spin states. Repeated measure-
ments of the spin states produce a Parisi-like distribution, indicating that the
system is in an SG phase. This experimental platform opens new avenues for
the study of driven-dissipative quantum systems, the emergence of glassy states
of matter, and physical optimization approaches.
