Realization of Nonadiabatic Quantum Computation via Reconstructing Geometric Phases in Non-Hermitian Systems

Nonadiabatic geometric quantum computation (NGQC) depending on the geometric phases has been developed as one excellent proposal for quantum control for fast and robust against control errors. However, previous NGQC protocols could not be strongly resilient against the noise from decay of bare states of a realistic system equivalently described by a non-Hermitian Hamiltonian. Here we propose a scheme to realize NGQC in non-Hermitian quantum systems. We show that the reconstructed purely nonadiabatic geometric phase can be specified as the real part of complex Aharonov-Anandan phase which corresponds to the complex solid angle swept by single-loop and non-unitary evolution of the system. Based on the phase, a universal set of geometric gates can be realized with a high fidelity. Moreover, we demonstrate that nonadiabatic process does not lead to the loss of fidelity from decaying

The Application of Augmented Reality Technology for the Anesthesiology Major

Anesthesiology is an important subject for in-depth research in the fields of clinical anesthesia, critical care medicine, first-aid and resuscitation, and pain treatment. As an important branch of clinical medicine, it has strong practicality and applicability. It has the commonality of clinical medicine and the specialty of anesthesiology. Carrying out anesthesiology practice teaching using augmented reality (AR) to simulate the experimental environment and scene simulation is of great significance to promoting the development of anesthesia practice teaching. This article mainly introduces the augmented reality technology. It not only analyzes the main forms of augmented reality technology in anesthesiology, but also explores the application of augmented reality technology for anesthesiology in the new era

Expression of monocyte chemotactic protein-3 mRNA in rat vascular smooth muscle cells and in carotid artery after balloon angioplasty

AbstractMonocyte chemotactic protein-3 (MCP-3) is a CC chemokine that functions in chemoattraction and activation of monocytes, T lymphocytes, eosinophils, basophils, natural killer cells and dendritic cells. The activation of the target cells by MCP-3 is via specific chemokine receptors CCR2 and CCR3, of which CCR2 is shared with MCP-1. MCP-1 and CCR2 have been implicated in vascular diseases including atherosclerosis and restenosis, that are known to be involved in inflammation (accumulation of T lymphocytes and monocytes) and smooth muscle cell (SMC) activation (proliferation, migration and matrix deposition). To investigate a potential role of MCP-3 in vascular injury, the present work examined its mRNA expression in rat aortic SMCs stimulated with various inflammatory stimuli including LPS, TNF-α, IL-1β, IFN-γ and TGF-β. A time- and concentration-dependant induction of MCP-3 mRNA in SMCs was observed by means of Northern analysis. A strikingly similar expression profile was observed for MCP-3 and MCP-1 mRNA in SMCs. Furthermore, MCP-3 mRNA expression was induced in rat carotid artery after balloon angioplasty. A significant induction in MCP-3 mRNA was observed in the carotid artery at 6 h (41-fold increase over control, P<0.001), 1 day (13-fold increase, P<0.001) and 3 days (6-fold increase, P<0.01) after balloon angioplasty as quantitated by reverse transcription and polymerase chain reaction. These data provide evidence for the cytokine-induced expression of MCP-3 in SMCs and in carotid artery after balloon angioplasty, suggesting a potential role of MCP-3 in the pathogenesis of restenosis and atherosclerosis
