Renormalization of magic and quantum phase transition in spin models
The interplay of quantum information theory and condensed matter physics has generated fruitful results, which promote our understanding of quantum phase transition. Magic, as a crucial resource in fault-toler...

Dynamics of atomic magic in the Jaynes–Cummings model
Magic (non-stabilizerness), as a basic quantum resource in the stabilizer formalism of quantum computation, has attracted considerable attention over the last two decades. Its significance and applications lie...

Detecting Magic States via Characteristic Functions
Magic (non-stabilizerness) is a crucial resource for universal fault-tolerant quantum computation in the stabilizer formalism, without which the computation can be classically emulated, as demonstrated by the ...

Faithful Multihop Two-Qubit Transmission Through GHZ-GHZ Channel
Quantum teleportation is an important method for transmitting quantum states between two quantum communication nodes. In this paper, we propose a low-latency quantum communication scheme based on Greenberger-H...

Dynamics of field nonclassicality in the Jaynes–Cummings model
Employing an informational quantifier for nonclassicality of bosonic field based on the Wigner–Yanase skew information, we investigate the dynamics of field nonclassicality in the Jaynes–Cummings model evolvin...

Skew information-based uncertainty relations for quantum channels
The most general quantum measurements in quantum mechanics are described by quantum channels (quantum operations), and intrinsic uncertainties emerge from the state–channel interaction. In this paper, we study...

Quantum criticality from Fisher information
Quantum phase transition is primarily characterized by a qualitative sudden change in the ground state of a quantum system when an external or internal parameter of the Hamiltonian is continuously varied. Inve...
