Abstract: We define an ensemble of random Clifford quantum circuits whose output state undergoes an entanglement phase transition between two volume-law phases as a function of measurement rate. Our setup maps exactly the output state to the ground space of a spin glass model. We identify the entanglement phases using an order parameter that is accessible on a quantum chip. We locate the transition point and evaluate a critical exponent, revealing spin glass criticality. Our work establishes an exact statistical mechanics theory of an entanglement phase transition.

Probing quantum floating phases in Rydberg atom arrays [61.242961328078245]
We experimentally observe the emergence of the quantum floating phase in 92 neutral-atom qubits. The site-resolved measurement reveals the formation of domain walls within the commensurate ordered phase. As the experimental system sizes increase, we show that the wave vectors approach a continuum of values incommensurate with the lattice.

Foliated order parameter in a fracton phase transition [0.0]
We study phase transition in the X-cube model in the presence of a non-linear perturbation. We show there is a first order quantum phase transition from a type I fracton phase to a magnetized phase. We introduce a non-local order parameter in the form of a foliated operator which can characterize the above phase transition.

Dissipative Floquet Dynamics: from Steady State to Measurement Induced Criticality in Trapped-ion Chains [0.0]
Quantum systems evolving unitarily and subject to quantum measurements exhibit various types of non-equilibrium phase transitions. Dissipative phase transitions in steady states of time-independent Liouvillians and measurement induced phase transitions are two primary examples. We show that a dissipative phase transition between a ferromagnetic ordered phase and a paramagnetic disordered phase emerges for long-range systems.
