Post-selected Criticality in Measurement-induced Phase Transitions
Dolly Nambi, Kabir Khanna, Andrew Allocca +4
Information-theoretic phase transitions, such as the measurement-induced phase transition (MIPT), characterize the robustness of quantum dynamics to local monitoring and are natura…
Universal monitored dynamics in multimode bosonic systems
Shivam Patel, Catherine McCarthy, Ahana Chakraborty +5
We propose a route to study monitored many-body dynamics in multimode bosonic systems using circuit quantum electrodynamics. In this experimental setting, we construct several boso…
Learning measurement-induced phase transitions using attention
Hyejin Kim, Abhishek Kumar, Yiqing Zhou +3
Measurement-induced phase transitions (MIPTs) epitomize new intellectual pursuits inspired by the advent of quantum hardware and the emergence of discrete and programmable circuit…
Measurement-Induced Entanglement in Conformal Field Theory
Kabir Khanna, Romain Vasseur
Local measurements can radically reshape patterns of many-body entanglement, especially in long-range entangled quantum-critical states. Yet, analytical results addressing the effe…
Flow to Nishimori universality in weakly monitored quantum circuits with qubit loss
Malte Pütz, Romain Vasseur, Andreas W. W. Ludwig +2
In circuit-based quantum state preparation, qubit loss and coherent errors are circuit imperfections that imperil the formation of long-range entanglement beyond a certain threshol…
Decoherence-induced self-dual criticality in topological states of matter
Qingyuan Wang, Romain Vasseur, Simon Trebst +2
Quantum measurements performed on a subsystem of a quantum many-body state can generate entanglement for its remaining constituents. The whole system including the measurement reco…
