Over the past few years,quantum computation based on superconducting circuits has achieved remarkable progress.A milestone occurred in 2019 when Google released Sycamore,a processor with 54 qubits,and claimed quantum supremacy by performing in just 100 s a specific computation which would take a classical supercomputer,as stated by Google’s team,10000 years to complete.[1]In 2021,a strong quantum advantage was demonstrated by Pan and his colleagues from the University of Science and Technology of China,using a quantum processor named Zuchongzhi,which has 66 functional qubits.[2]This year,the record of the number of quantum qubits has been lifted to 127 qubits.[3]Indeed,the number of qubits is limited to a few hundreds due to the finite space of dilution refrigerators,where the superconducting qubits must be placed to be isolated from thermal ***,this number is still several orders of magnitude away from the requirement of quantum error correction,which is essential for general-purpose quantum computers.[4–8].

在粮食储藏上利用氮气的方法已经有30多年的历史,但直到最近经济有效的变压吸附(PSA)和膜分离(MS)制氮设备的出现,才使得该技术在储粮上使用成为可能。本研究首先在25、30和35℃、99%、98%和97%氮气的环境下,对小麦、大麦、燕麦、羽扇豆和油菜籽中的花斑皮蠹、赤拟谷盗、谷蠹和米象成虫和非成虫虫态进行了为期4、3和2周的实验室生物测定。然后在终端用户LakeGrace和CBH(Cooperative BulkHandling)谷物进出口公司Albany出口港码头开展实仓验证,测定小麦、大麦和油菜籽中不同储粮害虫虫种和油菜籽瓢虫和肖叶甲类两种田间害虫的防治效果。同时对处理后的粮食品质进行了测定。实验结果表明,害虫死亡率随着氧气浓度降低、暴露时间和温度的增加而增加,富氮低氧在低温条件下不能100%致死花斑皮蠹幼虫。氮气处理对磷化氢抗性和敏感品系储粮害虫防治效果没有差异。与其他粮种相比,在油菜籽中的防治效果更好。各种粮种的水分含量、蛋白质、含油量、淀粉和籽粒颜色品质指标均未受到影响。成功开发了富氮低氧商业规模应用模式,为磷化氢高抗性害虫治理提供了解决方案,满足市场日益增长对无害虫和无化学残留粮食的需求。

为防治澳大利亚主要仓储害虫,开发富氮气调技术作为熏蒸剂的辅助手段。然而,由于成本问题,一直影响其在行业推广应用。本研究利用中国长顺安达公司的先进膜分离技术,与传统的制氮技术(变压吸附/PSA)进行性能比较,在西澳Kwinana的CBH粮食港,开展实仓应用实验,以解决阻碍其推广的运营和成本问题。为满足澳大利亚严格的标准操作条件,长顺安达专业团队对港口设备进行了升级改造,目标消杀成本设定为0.50澳元/吨粮(磷化氢的高端熏蒸成本)。研究表明,旧的PSA技术的运营成本为2.43澳元/吨粮,该技术在产生和维持控制害虫所需的99%氮气浓度水平方面也显示出操作局限性。相比之下,使用膜技术制氮的成本为0.99澳元/吨粮,其他性能增益还包括运行4.5天内即可产生所需的氮气浓度,且可维持14天以完全控制害虫。
