Quantum Simulations [Physics, Chemistry, Biology, Organisms, Materials...]

"The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that's an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer." - David Deutsch

"To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole." - David Deutsch

Digital Simulations

A Digital Quantum Simulator is an envisioned quantum device that can be programmed to efficiently simulate any other local system. It has an integrated Classical Host Computer. And works by implementing and executing Quantum Gates & Quantum Circuits.

Analog Simulations

Special purpose, analog quantum simulators designed to solve specific problems, such as how room-temperature superconductors work or how a particular protein folds.

We can create a simple physical system that obeys the same laws of motion as the system I’m trying to model—mixing nitrogen, oxygen, and hydrogen in a tank, for example. What goes on inside the tank is a real-world computation that tells me something about atmospheric turbulence under certain conditions.

It is the same with an analog quantum simulator—I use one controllable physical system to simulate another. For example, successfully simulating a superconductor with such a device would reveal the quantum mechanics of high-temperature superconductivity. That could lead to the manufacture of non-brittle superconducting materials for many uses, including building less-fragile quantum circuits.Hopefully, we can learn how to build a robust universal digital computer by experimenting with analog simulators.

Efficiency, Scale, Precision & Accuracy

For most problems we can get either precision, accuracy, efficiency or scale, for some problems we can get two, three or all four.

Simulating The God's Algorithm

"The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy, but the ones that contain the deepest explanations." - David Deutsch

"The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests." - David Deutsch

"Our best theories are not only truer than common sense, they make more sense than common sense." - David Deutsch

"A theory of reality must not only explain reality, but also knowledge about that reality because knowing reality is part of reality." ― Ashish Dalela, Quantum Meaning: A Semantic Interpretation of Quantum Theory

"Physical reality does not require that we be pleased with its mechanism." ― Kevin Michel, Moving Through Parallel Worlds To Achieve Your Dreams

"The universe has secrets just waiting to be unveiled." ― Gerald W. Scanlon
