Discovery of two-dimensional topological insulator such as Bi bilayer initiates challenges in exploring exotic quantum states in low dimensions. We demonstrate a promising way to realize the Kane-Mele-type quantum spin Hall (QSH) phase and the quantum anomalous Hall (QAH) phase in chemically-modified Bi and Sb bilayers using first-principles calculations. We show that single Bi and Sb bilayers ...

In this paper we investigate the effect of dephasing on proposed quantum gates for the solid-state Kane quantum computing architecture. Using a simple model of the decoherence, we find that the typical error in a CNOT gate is 8.3 × 10. We also compute the fidelities of Z, X, Swap, and Controlled Z operations under a variety of dephasing rates. We show that these numerical results are comparable...

Sarah Kane, who is a very prominent representative of in-yer-face theatre, raises her rebellious voice against social problems in an unprecedented way through plays, and the subordination women society one fundamental issues that playwright ponders on. She masterfully draws attention audience to patriarchal subjugation by employing violence plays. The present study examines Blasted (1995) Clean...
