First Browser-Based Quantum Computer Simulator Released 61

greg65535 (1209048) writes "Following the trend of on-line coding playgrounds like JSFiddle or CodePen, Google researchers unveiled the first browser-based, GPU-powered Quantum Computing Playground. With a typical GPU card you can simulate up to 22 qubits, write, debug, and share your programs, visualize the quantum state in 2D and 3D, see quantum factorization and quantum search in action, and even... execute your code backwards."

    Well let's compare. Geordie Rose spent years and millions of dollars trying (and succeeding) in building a computational device that works on radically different principles than existing computer tech, is actually useful for a lot of real-world tasks, and consumes virtually zero power - a huge feat in itself, even if it's not really a "quantum computer" in the traditional sense of the word. Whereas those people disagreeing with him are all ivory tower academics who have not built and do not plan to build any hardware. The most egregious of which is Scott Aaronson who is known for his delusional rants on everything from neuroscience to fundamental physics. I wonder which one has their head grounded more firmly in reality.

    But seriously though, the fundamental principles of gate-based and adiabatic quantum computing aren't that different; it's more a continuum where on one end you have highly decoherent classical behavior, on the other you have pure quantum behavior, and in the middle you have quantum+noise behavior where tiny entanglements are being generated and decohered on a rapid scale that is too short to do quantum computing but long enough to do adiabatic quantum computing. It's possible that by investing in AQC technology, as the technology matures it will give better and better entanglement and eventually approach a pure quantum computer in capability.

    Hold on a minute. If it's possible to simulate qubits using, at the bottom, bits, and, if qubits and quantum computing allow for performing NP calcs in parametric time (and hence breaking crypto), then haven't we already been able to do all of these things for decades?
