Blueshift Memory Ltd. , a Cambridge-based firm, has been doing exciting things since its inception in 2016. They are known for something called ‘Cambridge Architecture’. This is a special type of memory storage that is great for handling large amounts of data quickly. It’s very useful for tasks that need a lot of computing power, like artificial intelligence or virtual reality, because it can access stored memory at breakneck speed — a thousand times faster, to be exact.
Now, Blueshift is partnering with another company called Crypta Labs Ltd. from Oxford. Crypta Labs has created a special tool to make data encryption stronger, which is called a Quantum Random Number Generator (QRNG). The idea is that Blueshift will use Crypta Labs’ tool within ‘Cambridge Architecture’ to make storing its data more secure.
Peter Marusan, who started Blueshift and is also its chief technical officer, said their computer design already has strong security built into it. But by working with Crypta Labs, they’re adding an extra layer of protection that uses the rules of quantum physics. This means that the data in the storage memory is encrypted and can only be decrypted by a certain type of processor. Basically, they’re combining the realms of quantum computing with ordinary computer memory technology.
Quantum Optics Unit
Crypta Labs has developed the unique Quantum Optics Module (QOM) as part of their QRNG solution. Blueshift plans to use this in its own technology.
Blueshift was also awarded a grant last year to work on a special unit for computer vision artificial intelligence, based on the same Cambridge Architecture. It includes part of the design of another tech company called Codasip.
On the Crypta Labs side, they are delighted to work with Blueshift. According to Jose Garcia Coelho, their chief scientist, an essential part of data encryption is the random numbers. But many of the random numbers used today are not really random because they are generated by a system. This can make them vulnerable to attacks. This is why Crypta Labs uses particles of light to generate truly random numbers. They are looking forward to adding this secure Blueshift data storage technology.
In short, Blueshift Memory and Crypta Labs are joining forces to make data storage safer and faster, combining their innovative technology in new ways.
What is quantum cryptography?
Quantum cryptography is a secure communication method that reinforces the principles of quantum mechanics to protect data. The most well-known application of quantum cryptography is quantum key distribution (QKD), which is a method of securely sharing secret keys between two parties.
QKD operates on the basis of a fundamental property of quantum mechanics: any measurement of a quantum system can perturb the system. In the context of QKD, if an eavesdropper tries to intercept and measure quantum keys, its action will inevitably cause system disruption. This disruption can be detected by legitimate users, who will know that their security key has been compromised and can then give it away.
One of the most popular QKD protocols is the BB84 protocol, proposed by Charles Bennett and Gilles Brassard in 1984. In this protocol, a sender (often called Alice) sends quantum bits (qubits) to a receiver (often called Bob) using different polarization states. photons, while an eavesdropper (usually called Eve) tries to measure these qubits.
Because of the laws of quantum mechanics, Eve cannot measure a quantum state without disturbing it, which Alice and Bob can detect. If there is 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 cannot be achieved using traditional cryptographic methods, which makes quantum cryptography a very promising technology for secure communications in an era of ever-increasing cybersecurity threats.
