Spectral properties and coding transitions of Haar-random quantum codes
Grace M. Sommers, J. Alexander Jacoby, Zack Weinstein +2
A quantum error-correcting code with a nonzero error threshold undergoes a mixed-state phase transition when the error rate reaches that threshold. We explore this phase transition…

Measurement-induced phase transitions in systems with diffusive dynamics
Hyunsoo Ha, Akshat Pandey, Sarang Gopalakrishnan +1
The competition between scrambling and projective measurements can lead to measurement-induced entanglement phase transitions (MIPT). In this work, we show that the universality cl…

Spectral gaps of local quantum channels in the weak-dissipation limit
J. Alexander Jacoby, David A. Huse, Sarang Gopalakrishnan
We consider the dynamics of generic chaotic quantum many-body systems with no conservation laws, subject to weak bulk dissipation. It was recently observed [T. Mori, arXiv:2311.103…
