The post A Grounded Look At The Issues appeared on BitcoinEthereumNews.com.

I won’t pretend to deeply understand quantum physics, or quantum computing specifically, I don’t, but I grasp enough to know that the theory underlying it is sound.  For certain classes of parallelizeable computations, the physical properties of quantum computers’ qubits allow searching for correct answers in very large search spaces exponentially more efficiently than classical computers. We have proven mathematical algorithms for these faster computations for a number of different computational problems, and there are many more that don’t yet have proven algorithms.  The question is whether it is practical to achieve from an engineering perspective, i.e. can we actually build machines that are efficient, reliable, and powerful enough to actually take advantage of quantum theory in a way that is useful at solving real problems?  That’s why I went to the Quantum Bitcoin Summit at the Bitcoin Presidio in San Francisco.  The small day and a half summit was attended by experts in both the quantum computing industry as well as Bitcoin developers. There were presentations on the current state of quantum computing, the specific risks to Bitcoin we would have to deal with after the development of a practical quantum computer, potential solutions we have to post-quantum cryptography, as well as debates over how to handle different aspects of the problem.  The State Of Things There are four different architectures being developed by the different companies working on quantum computing projects. Neutral atoms, trapped ions, superconducting circuits, and photonics. All of these different physical platforms present themselves with different trade offs in terms of computational speed, stability, and scalability of the underlying physical architecture.  Most of the research for these different platforms has chiefly focused on one issue up to this point: error correction. The entire concept of quantum computing is based on the qubit, the quantum version…
