Phase diagram of the three-dimensional subsystem toric code
Yaodong Li, C. W. von Keyserlingk, Guanyu Zhu +1
Subsystem quantum error-correcting codes typically involve measuring a sequence of non-commuting parity check operators. They can sometimes exhibit greater fault-tolerance than con…
Continuous symmetry breaking in adaptive quantum dynamics

Adaptive quantum circuits, in which unitary operations, measurements, and feedback are used to steer quantum many-body systems, provide an exciting opportunity to generate new dyna…
Operator relaxation and the optimal depth of classical shadows
Matteo Ippoliti, Yaodong Li, Tibor Rakovszky +1
Classical shadows are a powerful method for learning many properties of quantum states in a sample-efficient manner, by making use of randomized measurements. Here we study the sam…

We investigate the prospects of employing the linear cross-entropy to experimentally access measurement-induced phase transitions (MIPT) without requiring any postselection of quan…

Yaodong Li, Romain Vasseur, Matthew P. A. Fisher +1
We introduce an exact mapping of Clifford (stabilizer) random tensor networks (RTNs) and monitored quantum circuits, onto a statistical mechanics model. With Haar unitaries, the fu…
Decodable hybrid dynamics of open quantum systems with Z_2 symmetry
Yaodong Li, Matthew P. A. Fisher
We explore a class of "open" quantum circuit models with local decoherence ("noise") and local projective measurements, each respecting a global Z_2 symmetry. The model supports a…

Monitored quantum dynamics reveal quantum state trajectories which exhibit a rich phenomenology of entanglement structures, including a transition from a weakly-monitored volume la…
Entanglement Negativity at Measurement-Induced Criticality

We study stabilizer quantum error correcting codes (QECC) generated under hybrid dynamics of local Clifford unitaries and local Pauli measurements in one dimension. Building upon 1…
Emergent conformal symmetry in non-unitary random dynamics of free fermions

We present random quantum circuit models for non-unitary quantum dynamics of free fermions in one spatial dimension. Numerical simulations reveal that the dynamics tends towards st…

We establish the emergence of a conformal field theory (CFT) in a (1+1)-dimensional hybrid quantum circuit right at the measurement-driven entanglement transition by revealing spac…
Non-Kitaev spin liquids in Kitaev materials
