極客產品下午12:55藍移內存有限公司,公司總部在劍橋,一直在令人興奮的事情發生,因為它成立於2016年。它以所謂的“劍橋架構”。這是一種特殊的存儲器,偉大的快速處理的數據量很大。來說它是非常有用的任務,需要大量的計算能力,像人工智能和虛擬現實,因為它可以訪問存儲內存非常快——快一千倍,要精確。現在,藍移正與另一個叫Crypta實驗室有限公司來自牛津的公司。Crypta實驗室想出了一個特殊的工具進行數據加密,叫做量子隨機數生成器(QRNG)。藍移的想法是將使用Crypta實驗室的工具在其“劍橋架構的數據存儲更加安全。彼得·Marosan開始藍移,也是其主要技術人員,說他們的電腦設計已內置強大的安全。但通過與Crypta實驗室合作,他們更多一層保護,使用量子物理學的規則。這意味著存儲器中的數據編碼,隻能由一個特定類型的處理器解碼。 Basically, they’re combining the worlds of quantum computing and regular computer memory technology. Quantum Optics Module Crypta Labs has developed a unique Quantum Optics Module (QOM) as part of their QRNG solution. Blueshift plans to use this within its own tech. Blueshift also got a grant last year to work on a special AI module for computer vision, based on the same ‘Cambridge Architecture’. It includes a part designed by another tech company called Codasip. From Crypta Labs’ side, they’re thrilled to be working with Blueshift. According to Jose Garcia Coello, their chief scientist, a key part of data encryption is random numbers. But many random numbers used today aren’t really random because they’re made by a system. This can make them vulnerable to attacks. That’s why Crypta Labs uses light particles to generate truly random numbers. They’re looking forward to adding this secure tech to Blueshift’s data storage. In short, Blueshift Memory and Crypta Labs are joining forces to make data storage safer and faster, combining their innovative tech in new ways. What is Quantum cryptography? Quantum cryptography is a method of secure communication that leverages the principles of quantum mechanics to protect data. The most well-known application of quantum cryptography is quantum key distribution (QKD), which is a way to share secret keys securely between two parties. QKD operates based on a key property of quantum mechanics: any measurement of a quantum system can disturb the system. In the context of QKD, if an eavesdropper tries to intercept and measure the quantum keys, their action would inevitably cause a disturbance in the system. This disturbance can be detected by the legitimate users, who will know that their secure key has been compromised and can then abandon it. One of the most common QKD protocols is the BB84 protocol, proposed by Charles Bennett and Gilles Brassard in 1984. In this protocol, the sender (often called Alice) sends quantum bits (qubits) to the receiver (often called Bob) using different polarization states of photons, while an eavesdropper (usually named Eve) attempts to measure these qubits. Because of the laws of quantum mechanics, Eve can’t measure the quantum state without disturbing it, which Alice and Bob can detect. If there’s no eavesdropping, Alice and Bob can use this shared key to encrypt and decrypt messages , confident in the knowledge that their communication is secure. This level of security is unachievable with traditional cryptographic methods, making quantum cryptography a highly promising technology for secure communications in an era of ever-increasing cybersecurity threats.
