The entanglement criterion of multiqubits
Hyuk-jae Lee, Sung Dahm Oh, Doyeol Ahn
We present an entanglement criterion for multiqubits by using the quantum correlation tensors which rely on the expectation values of the Pauli operators for a multiqubit state. Ou…

Current and noise expressions for radio-frequency single-electron transistors
Jung Hyun Oh, D. Ahn, S. W. Hwang
We derive self-consistent expressions of current and noise for single-electron transistors driven by time-dependent perturbations. We take into account effects of the electrical en…

Dissipation of quantum information near the event horizon of Schwarzschild black holes
D. Ahn, S. W. Hwang
We found that the Wigner rotation of a particle with spin 1/2, which is unitary in Minkowski spacetime, becomes non-unitary as the particle is falling onto the black hole. This imp…
