It would appear QD company's may have huge leverage over the block chain field....

Much of blockchain’s allure arises from its security benefits. The tech allows a ledger of transactions to be distributed between a large network of computers. No single user can break into and change the ledger. This makes it both public and secure.

But combined with another emerging (and much hyped) technology, quantum computing, blockchain’s seemingly immutable ledgers would be under threat.

Like blockchain, quantum computing has been making progress and headlines too.

The number of quantum computing companies and researchers continues to grow. And while there is a lot of focus on hardware, many are looking into the software as well.

Cryptography is a commonly debated topic because quantum computing poses a threat to traditional forms of computer security, most notably public key cryptography, which undergirds most online communications and most current blockchain technology.

But first, how does computer security work today?

Public key cryptography uses a pair of keys to encrypt information: a public key which can be shared widely and a private key known only to the key’s owner. Anyone can encrypt a message using the intended receiver’s public key, but only the receiver can decrypt the message using her private key. The more difficult it is to determine a private key from its corresponding public key, the more secure the system.
