However, this does not necessarily mean that a quantum computer will outperform a classical … But all the tasks performed by a classical computer can not be done better with quantum computing. It is simple to use. Abstract In this short document, a definition of what Quantum Cryptography is will be given, and it will be compared to the traditional (or Classical) approaches. Carl J. Williams, in Advances in Computers , 2002 Quantum cryptography offers some potentially enormous advantages over conventional cryptosystems, and may also be the only way to secure communications against the power of quantum computers. Quantum cryptography offers the advantages of ‘unconditional security’ and sniffing detection. Quantum Computing and Cryptography: Analysis, Risks, and Recommendations for Decisionmakers Jake Tibbetts 1 UC Berkeley Introduction Some influential American policymakers, scholars, and analysts are extremely concerned with the effects that quantum computing will have on national security. A post-quantum cryptosystem is one which is not known to be breakable in polynomial time (described above) by a full-scale quantum computer. But Quantum Cryptography has also disad-vantages. Quantum cryptography has become the first commercial application of the principles of quantum information. Quantum cryptography is the only approach to privacy ever proposed that allows two parties (who do not share a long secret key ahead of time) to communicate with provably perfect secrecy under the nose of an eavesdrop-per endowed with unlimited computational power and whose technology is limited by nothing but the fundamental laws of nature. We will present an overview of the recent progress related to the deployment of quantum cryptography to secure real-world networks and point at some challenges. Of course it is completely possible to use the algorithms incorrectly. There have been shown that quantum computer will have all the abilities that a classical computer have and can perform all the tasks of a classical computer. Given the enormous potential power of quantum technology, it should go without saying that those who possess this technology in the future will have a major advantage over those who do not—in the realms of politics, finance, security, and more.
