About this deal

Actually electrical engineers do use complex numbers to talk about electrical pulses. So yes you could use electrical impulses to talk about complex numbers. It’s true that the usual formulation of the uncertainty principle involves a peculiarity of the Schrödinger equation—namely, that position and momentum are conjugate observables—but I prefer the more abstract formulation, which applies to any pair of conjugate observables, in Hilbert spaces of any dimension (the finite case probably being the clearest). And in the latter case, yes, it’s just a logical consequence of the basic axioms of QM, the ones that talk about amplitudes. Unless instead it’s base 3 due to radix economy. Who knows, maybe that’s something an alien civilization might actually care about. 😛

A pure state is not measurable, because the global phase cannot be measured, The global phase is absent for the description by the density matrix, and it turns out that the density matrix is indeed measurable (in a suitable sense). On the topic of experimental demonstration of quantum supremacy, in your initial paper on Boson Sampling with Alex, you proved that BS being efficiently solvable by a classical computer implies that the polynomial hierarchy collapses to the third level. Is there any hope for reducing the collapse level further? It seems like the primary barrier is that the universal hashing scheme gives rise to BPP ppnl and Sniffnoy: I always assumed the alien nerd would be calculate the billionth integer in the continued fraction expansion of pi. ( http://oeis.org/A001203) to each state of a QM system, there exists a corresponding state of the environment that it is immersed in”.

This book uses QM in normal handwaving mode. By information, the author means his definition of dynamic information, which is something like information(flow) per time. Higher energy is normally associated with shorter times. What is good about this book is that it really discusses the time dynamics, which is otherwise often neglected. I wonder what the Kolmogorov complexity size of that QM description would be, not including the seed? As to me, I don’t accept the position that randomness exists in a metaphysical sense. This point of our difference is philosophical in nature; in fact even you yourself said “ontologicaly.” But QM is not a philosophical theory—it is not a branch of or theory in ontology (or metaphysics) any more than it is not a branch of theology. QM is a theory of physics. Don’t club the two together. Another aspect of Quantum Computation that’s difficult to relate to, particularly for software engineers, is how quantum algorithms are developed. Students might like to create their characters in the paint program (such as Paint or Tux Paint). Students should draw their characters in a number of poses. This allows for more realistic movements, such as walking. Students can import digital photographs (Scratch and PowerPoint® both allow users to import images from elsewhere.) MAIN ACTIVITIES

In general, the description of objects (including humans and robots) by quantum mechanics depends on who is describing them, from whose observational viewpoint the description takes place. That agent, the observer, plays a special role in the description. In rather generic situations (often caricatured as the Wigner’s friend thought experiment), two observers may use very different wave functions in the same situation. A key point is that the collapse of the wave function is always a subjective event.

It’s not really the fact of linear operators (i.e. linearly evolving amplitudes) which gives QM its peculiar character. The peculiarity of QM lies in the necessity of measurement, and the collapse postulate which an act of measurement involves. In other words, the peculiarity of QM lies in the “quantum jumps.” Schrodinger was unhappy only with this part of QM; and it is only this part that makes QM as we know it, incomplete. ppnl #66: The trouble with that intuition arises when you consider an example like the singlet state, |00>+|11>. Staring at that state, it seems obvious that there are two “branches”: one with two copies of 0 and the other with two copies of 1. Right? The problem is, the exact same state can be rewritten as To the second: to define “isolated system,” you should first define a tensor product Hilbert space; then a system is isolated if it lives in one tensor factor and its Hamiltonian acts only on that factor.
