Quantum computers could crack today’s encrypted messages. That’s a problem

20191023 google quantum computer lab 010
Google plans to make million-qubit quantum computers by 2029 that are much more powerful than this system it showed in 2019. Stephen Shankland/CNET Quantum computers, if they mature enough, will be able to crack much of today's encryption. That'll lay bare private communications, company data and military secrets.Today's quantum computers are far too primitive to do so. But data surreptitiously gathered now could still be sensitive when more powerful quantum computers come online in a few years.The computing industry is well aware of this potential vulnerability. Some companies have embarked on an effort to create, test and adopt new encryption algorithms impervious to quantum computers. Some of...

“Data Island” Problem Can Be Solved by Combining Privacy Computing AI and Blockchain Technology – IT Business Net

Data Island Problem Can Be Solved by Combining Privacy Computing
Platon Now Offers Breakthrough Solutions to Break the “Data Island” and Release the Value Potential Singapore, Singapore–(Newsfile Corp. – May 11, 2021) – During the COVID-19 pandemic, medical networking services developed rapidly, and big data played a key role in the development. In the medical industry, new medical models and cutting-edge research also require a large number of patient data to verify. However, due to the lack of effective privacy protection, data cannot be shared, resulting in the “data island” phenomenon, which has become a big problem to be solved. At the same time, the widespread use of medical big data also triggered the issue of privacy leaks and data abuse, and raised social concerns about data security and privacy protection. These problems exist not only in the medical industry, but also in other...

IBM just solved this quantum computing problem 120 times faster than previously possible

Using a combination of tweaked algorithms, improved control systems and a new quantum service called Qiskit Runtime, IBM researchers have managed to resolve a quantum problem 120 times faster than the previous time they gave it a go. Back in 2017, Big Blue announced that, equipped with a seven-qubit quantum processor, its researchers had successfully simulated the behavior of a small molecule called lithium hydride (LiH). At the time, the operation took 45 days. Now, four years later, the IBM Quantum team has announced that the same problem was solved in only nine hours.  The simulation was run entirely on the cloud, through IBM's Qiskit platform – an open-source library of tools that lets developers around the world create quantum programs and run them on prototype quantum devices that IBM makes available over the...

The new technology can take partial information and produce intelligent inferences, according to new research from Cambridge Quantum Computing. Image: iStockphoto/a-image As artificial intelligence and machine learning algorithms have received attention for making accurate predictions--in everything from judging the outcome of human rights trials to predicting the winner of the Kentucky Derby to identifying cancer--another new technology has now been applied to the task of reasoning: quantum computing. In a new paper, scientists at Cambridge Quantum Computing exhibited how quantum computing, still a nascent field, can be useful in making practical decisions. The aim, according to the head of...
