Nonadiabatic holonomic quantum computers serve as the physical platform for nonadiabatic holonomic quantum *** quantum computation has entered the noisy intermediate-scale era, building accurate intermediate-scale nonadiabatic holonomic quantum computers is clearly necessary. Given that measurements are the sole means of extracting information, they play an indispensable role in nonadiabatic holonomic quantum computers. Accordingly, developing methods to reduce measurement errors in nonadiabatic holonomic quantum computers is of great importance. However, while much attention has been given to the research on nonadiabatic holonomic gates, the research on reducing measurement errors in nonadiabatic holonomic quantum computers is severely lacking. In this study, we propose a measurement error reduction method tailored for intermediate-scale nonadiabatic holonomic quantum computers. The reason we say this is because our method can not only reduce the measurement errors in the computer but also be useful in mitigating errors originating from nonadiabatic holonomic gates. Given these features,our method significantly advances the construction of accurate intermediate-scale nonadiabatic holonomic quantum computers.

A novel elastic metamaterial is proposed with the aim of achieving lowfrequency broad bandgaps and bandgap regulation. The band structure of the proposed metamaterial is calculated based on the Floquet-Bloch theorem, and the boundary modes of each bandgap are analyzed to understand the effects of each component of the unit cell on the bandgap formation. It is found that the metamaterials with a low elastic modulus of ligaments can generate flexural wave bandgaps below 300 Hz. Multi-frequency vibrations can be suppressed through the selective manipulation of bandgaps. The dual-graded design of metamaterials that can significantly improve the bandgap width is proposed based on parametric studies. A new way that can regulate the bandgap is revealed by studying the graded elastic modulus in the substrate. The results demonstrate that the nonlinear gradient of the elastic modulus in the substrate offers better bandgap performance. Based on these analyses, the proposed elastic metamaterials can pave the way for multi-frequency vibration control, low-frequency bandgap broadening, and bandgap tuning.

研究了TiO_(2)含量对Dy_(2)O_(3)-Al_(2)O_(3)-SiO_(2)(DAS)玻璃的结晶行为、微观结构及相组成的影响,并分析了结晶过程中孔洞的形成机理。结果表明,随着TiO_( 2)含量的增加,微晶玻璃的晶化激活能先升高后降低。当TiO_(2)含量为6 wt.%时,DAS微晶玻璃的晶化激活能达到最高,说明其晶化能力最差。TiO_(2)含量变化并未改变该体系微晶玻璃的晶化形式,所有微晶玻璃样品的结晶方式均为表面结晶,且均存在Dy_(2)Si_(2)O_(7)。在TiO_(2)含量为0 wt.%的样品中还观察到球状Al_(2)O_(3)颗粒。当TiO_(2)含量高于6 wt.%的样品中则生成了Al_(2)SiO_(5)。另外,完全晶化的微晶玻璃样品中存在孔洞,孔洞的形成是由于结晶相与玻璃相之间的密度差异。孔洞的形态及分布则受到结晶相的生长速度、结晶相的致密程度与结晶相形态的共同影响。
