Mar 14, 2019 · "So far as we know, quantum computers seem to be theoretically possible, and building them is just a matter of very hard engineering," he said. "We know that if an appropriate quantum computer can be built, it could run Shor's algorithm and other variants that would break most public-key encryption we use today.

A new Computer. Researchers from MIT say that they have developed the world’s first five-atom quantum computer, and they assert that it is capable of cracking today’s traditional encryption Quantum computers might be able to break some of the today’s encryption methods, but not all of them. Compared to the vastly used asymmetric encryption, symmetric encryption algorithms are somewhat safe from the threat of quantum computing. Quantum computers strong enough to crack today’s encryption are at least a decade away, but the market for quantum-safe applications is already developing. Jul 11, 2019 · Blockchain developers don’t need a quantum computer in order to implement a quantum-resistant encryption scheme, and some of these schemes are actually very efficient and economical. That said, in order to ensure that a network is truly quantum-secure, developers would need a way to make sure all users and nodes update their software. Mar 14, 2019 · Quantum computing is nothing short of revolutionary. If you think this is a science fiction subject, take a look at The Quantum Computing Report and check out how global giants such as Intel, Google, IBM and Microsoft are investing heavily in the development of quantum computers. As quantum computing matures, it's going to bring unimaginable increases in computational power along with it -- and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there's still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he's fighting quantum with quantum: designing

## Dec 13, 2018 · RSA is the standard cryptographic algorithm on the Internet. The method is publicly known but extremely hard to crack. It uses two keys for encryption. The public key is open and the client uses it…

George Sidman CEO, TrustWrx, Inc. Quantum computing has become a very hot topic the last few years, promising the kind of speed and compute power that some believe could make encryption obsolete. If true, that would obviously present a clear and present danger to existing security solutions. Many security vendors that use single layer encryption …

### May 18, 2018 · Quantum computers will be able to instantly break the encryption of sensitive data protected by today's strongest security, warns the head of IBM Research.

Quantum computing will change the encryption game, but it is not yet clear how much it will change. It's not clear because we are not yet certain what sorts of problems quantum computers can solve. As mentioned, RSA is dramatically weakened by quantum computing because the factoring of primes can be done in polynomial time using Shor's Algorithm. Modern encryption techniques, unlike the “obscure the message” idea in historical ciphers, rely on some hard mathematical problem. For example, RSA is difficult to break as long as the “RSA problem” (finding [math]e^{th}[/math] roots modulo a larg
