Google<\/a> has achieved an experimental milestone of scaling a logical qubit, demonstrating for the first time that it's possible to reduce errors by increasing the number of qubits, its CEO Sundar Pichai<\/a> has said.

In
quantum computing<\/a>, a qubit is a basic unit of quantum<\/a> information that can take on richer states that extend beyond just 0 and 1.

\"Our breakthrough represents a significant shift in how we operate quantum computers. Instead of working on the physical qubits on our quantum processor one by one, we are treating a group of them as one logical qubit,\" said Pichai.

As a result, a logical qubit that Google made from 49 physical qubits was able to outperform one it made from 17 qubits, according to the research published in the journal Nature.

Google's quantum computers work by manipulating qubits in an orchestrated fashion that it calls quantum algorithms.

The challenge is that qubits are so sensitive that even stray light can cause calculation errors -- and the problem worsens as quantum computers grow.

\"This has significant consequences, since the best quantum algorithms that we know for running useful applications require the error rates of our qubits to be far lower than we have today. To bridge this gap, we will need
quantum error correction<\/a>,\" Pichai explained.

Quantum error<\/a> correction protects information by encoding it across multiple physical qubits to form a \"logical qubit,\" and is believed to be the only way to produce a large-scale quantum computer with error rates low enough for useful calculations.

\"Instead of computing on the individual qubits themselves, we will then compute on logical qubits. By encoding larger numbers of physical qubits on our quantum processor into one logical qubit, we hope to reduce the error rates to enable useful quantum algorithms,\" said Pichai.

Three years ago, Google quantum computers were the first to demonstrate a computational task in which they outperformed the fastest supercomputers.

Someday, said Pichai, quantum computers will be used to identify molecules for new medicines, create fertilisers using less energy, design more efficient sustainable technologies from batteries to nuclear fusion reactors, and produce physics research that will lead to advances we can't yet imagine.

\"That's why we're working on eventually making quantum hardware, tools and applications available to customers and partners, including through
Google Cloud<\/a>, so that they can harness the power of quantum in new and exciting ways,\" Pichai noted.<\/body>","next_sibling":[{"msid":98267502,"title":"Airtel 5G crosses 10 million unique users","entity_type":"ARTICLE","link":"\/news\/airtel-5g-crosses-10-million-unique-users\/98267502","category_name":null,"category_name_seo":"telecomnews"}],"related_content":[{"msid":"98266659","title":"Layoffs avoided 'much worse' issues, Sundar Pichai tells Google employees","entity_type":"IMAGES","seopath":"tech\/technology\/google-achieves-quantum-error-correction-milestone-sundar-pichai\/layoffs-avoided-much-worse-issues-sundar-pichai-tells-google-employees","category_name":"Google achieves quantum error correction milestone: Sundar Pichai","synopsis":false,"thumb":"https:\/\/etimg.etb2bimg.com\/thumb\/img-size-104010\/98266659.cms?width=150&height=112","link":"\/image\/tech\/technology\/google-achieves-quantum-error-correction-milestone-sundar-pichai\/layoffs-avoided-much-worse-issues-sundar-pichai-tells-google-employees\/98266659"}],"msid":98268343,"entity_type":"ARTICLE","title":"Google achieves quantum error correction milestone: Sundar Pichai","synopsis":"In quantum computing, a qubit is a basic unit of quantum information that can take on richer states that extend beyond just 0 and 1.","titleseo":"telecomnews\/google-achieves-quantum-error-correction-milestone-sundar-pichai","status":"ACTIVE","authors":[],"Alttitle":{"minfo":""},"artag":"IANS","artdate":"2023-02-27 12:46:29","lastupd":"2023-02-27 12:47:28","breadcrumbTags":["Google","quantum","quantum error","quantum computing","google cloud","Sundar Pichai","quantum error correction","Google ceo","internet"],"secinfo":{"seolocation":"telecomnews\/google-achieves-quantum-error-correction-milestone-sundar-pichai"}}" data-authors="[" "]" data-category-name="" data-category_id="" data-date="2023-02-27" data-index="article_1">

谷歌实现量子纠错的里程碑:Sundar Pichai

在量子计算,一个量子位的量子信息的基本单位,可以在富裕国家扩展不仅仅是0和1。

谷歌取得了一个实验性的里程碑的扩展逻辑量子位,首次证明可以减少错误通过增加量子位的数量,其首席执行官Sundar Pichai有说。

量子计算,一个量子位的基本单位量子信息可以在富裕国家扩展不仅仅是0和1。

“我们突破重大转变了我们如何操作量子计算机。而不是在物理量子比特量子处理器上一个接一个,我们将其中一组作为一个逻辑量子位,“Pichai说。

因此,逻辑量子位,谷歌由49个物理量子位可以超越一个由17个量子位,根据这项研究发表在《自然》杂志上。

谷歌通过操纵量子位的量子计算机工作策划时尚,它调用量子算法。

量子位的挑战是如此敏感,即使是杂散光会导致计算错误,问题恶化随着量子计算机的发展。

“这具有重大影响,因为最好的量子算法,我们知道有用的应用程序需要运行量子位的错误率远远低于我们今天。弥合这一差距,我们需要量子纠错”,Pichai解释说。

量子错误修正保护信息通过编码跨多个物理量子位形成一个“逻辑量子位,”和被认为是产生大规模的量子计算机的唯一方法错误率低足够有用的计算。

”而不是个别量子位元的计算,我们将计算逻辑量子位。通过编码大量的物理量子比特量子处理器为一个逻辑量子位,我们希望减少错误率,使有用的量子算法,“Pichai说。

三年前,谷歌量子计算机是第一个来演示一个计算任务,他们比最快的超级计算机。

Pichai说,总有一天,量子计算机将被用于确定新的药物分子,创建化肥使用更少的能源,设计更高效的可持续技术从电池到核聚变反应堆,并产生物理研究,将导致进步我们还无法想象。

“这就是为什么我们正在努力最终使得量子硬件,工具和应用程序提供给客户和合作伙伴,包括通过谷歌云,这样他们就可以利用量子在新的和令人兴奋的方面,”Pichai说。
