物理学家实现量子比特计算突破 诸平 a. Experimental SC circuit of device I with qubits and couplers in a square geometry. The light-grey dashed rectangles represent dimers that constitute the chain with intracoupling Ja, intercoupling Je and small cross-coupling Jx. b. Schematic (upper ...
量化高维量子态的新测量提供了量子未来的一瞥 诸平 The micro-ring resonator, shown here as a closed loop, generated high-dimensional photon pairs. Researchers examined these photons by manipulating the phases of different frequencies, or colors, of light and mixing frequencies, as shown ...
物理学家探索了蜂巢状材料的“惊人”变形特性 诸平 By exposing a honeycomb-like material with a specific kind of magnetic field, yellow arrow, researchers can create order among the loop currents, light blue, within that material. Electrons, in green, can then pass through the material muc ...
核聚变研究的一个主要问题的新解决方案 诸平 Fig. 1 Left: Cross section of the separatrix of the high (solid) and low (dashed)lHFS→LFStime points.lHFS→LFSis the length of a field line spanning from the LFS to the HFS midplane. A poloidal projection oflHFS→LF ...
天大人造超强蚕丝比蜘蛛丝强 70% 诸平 Fig. 1 Spider silk is strong, but it is hard to farm. New research reveals how silk naturally produced by silkworms can be made 70% stronger than spider silks. Fig. 2 Stress-strain curves of representative artificial and natural silks. ...
