Coherent information as a mixed-state topological order parameter of fermions
Ze-Min Huang, Luis Colmenarez, Markus Müller +1
Quantum error correction protects quantum information against decoherence provided the noise strength remains below a critical threshold. This threshold marks the critical point fo…
Entanglement in bipartite X-states: Analytical results for the volume of states with positive partial transpose
Yaqing Xy Wang, József Zsolt Bernád
We provide an analytical formula for the volume ratio between bipartite X-states with positive partial transpose and all bipartite X-states. The result applies to arbitrary $m \tim…
Universal pulses for superconducting qudit ladder gates
Boxi Li, F. A. Cárdenas-López, Adrian Lupascu +1
Qudits, generalizations of qubits to multi-level quantum systems, offer enhanced computational efficiency by encoding more information per lattice cell, avoiding costly swap operat…
Fundamental thresholds for computational and erasure errors via the coherent information
Luis Colmenarez, Seyong Kim, Markus Müller
Quantum error correcting (QEC) codes protect quantum information against environmental noise. Computational errors caused by the environment change the quantum state within the qub…
Digital-Analog Simulations of Schrödinger Cat States in the Dicke-Ising Model
Dmitriy S. Shapiro, Yannik Weber, Tim Bode +2
The Dicke-Ising model, one of the few paradigmatic models of matter-light interaction, exhibits a superradiant quantum phase transition above a critical coupling strength. However,…
Roughening dynamics of interfaces in the two-dimensional quantum Ising model
Wladislaw Krinitsin, Niklas Tausendpfund, Matteo Rizzi +2
The properties of interfaces are key to understand the physics of matter. However, the study of quantum interface dynamics has remained an outstanding challenge. Here, we use large…
