Robust Universal Photon Blockade in a Bimodal Jaynes-Cummings Model via Kerr Nonlinearity
Guohao Chang, Hunduz Halemjan, Shangyun Liu +2
Universal photon blockade in a two-mode Jaynes-Cummings model incorporating third-order Kerr nonlinearity is demonstrated with a single two-level atom coupled to a waveguide microc…
Error Resilience of Fracton Codes and Near Saturation of Code-Capacity Threshold in Three Dimensions
Giovanni Canossa, Lode Pollet, Miguel A. Martin-Delgado +2
Fracton codes have been intensively studied as novel topological states of matter, yet their fault-tolerant properties remain largely unexplored. Here, we investigate the optimal t…
Quantum simulation in the entanglement picture
D. -S. Wang, X. Xu, Y. -D. Liu
The notion of ``picture'' is fundamental in quantum mechanics. In this work, a new picture, which we call entanglement picture, is proposed based on the novel channel-state duality…
Quantum Energy Teleportation under Equilibrium and Nonequilibrium Environments
Xiaokun Yan, Kun Zhang, Jin Wang
Quantum energy teleportation (QET), implemented via local operations and classical communication, enables carrier-free energy transfer by exploiting quantum resources. While QET ha…
The power of quantum catalytic local operations
Patryk Lipka-Bartosik, Jessica Bavaresco, Nicolas Brunner +1
A key result in entanglement theory is that the addition of a catalyst dramatically enlarges the set of possible state transformations via local operations and classical communicat…
Phenomenological Noise Models and Optimal Thresholds of the 3D Toric Code
Ji-Ze Xu, Yin Zhong, Miguel A. Martin-Delgado +2
Three-dimensional (3D) topological codes offer the advantage of supporting fault-tolerant implementations of non-Clifford gates, yet their performance against realistic noise remai…
