【科学网】科学家实现太比特级高保真金刚石级数据存储
近日,中国科学技术大学的杜江峰&王亚及其研究团队取得一项新进展。经过不懈努力,他们实现太比特级高保真金刚石级数据存储。相关研究成果已于2024年11月27日在国际知名学术期刊《自然—光子学》上发表。
本文介绍了一种利用荧光空位中心作为稳健存储单元的金刚石存储介质,该介质提供了高达14.8Tbit/cm3的存储密度、200飞秒的短写入时间,以及预估可达数百万年的超长免维护使用寿命。
通过平面和体积成像实现的高速读出展示了超过99%的高保真度,表明该方法满足了数字数据存储的实际需求,并为未来的存储需求提供了有前景的解决方案。
据悉,在数字化信息时代,实现高效且持久的数据存储解决方案至关重要。对于推动实用型数字数据存储技术的持续发展而言,提升存储容量、数据吞吐量、设备寿命以及降低能耗等方面的创新是迫切需求。

Abstract: In the era of digital information, realizing efficient and durable data storage solutions is paramount. Innovations in storage capacity, data throughput, device lifespan and energy consumption are pressing necessities for the continuous progression of practical digital data storage technologies. Here we present a diamond storage medium that exploits fluorescent vacancy centres as robust storage units and provides a high storage density of 14.8Tbit cm-3, a short write time of 200fs and an estimated ultralong maintenance-free lifespan on the scale of millions of years. High-speed readout through plane and volume imaging is demonstrated with a high fidelity exceeding 99%, showing that the approach addresses the practical demands of digital data storage and provides a promising solution for future storage requirements.
