Sorry to go off-topic, it's just that quality and service are both down and prices are way up on the train service that belongs to those cards. (I do have that card in my wallet though, for when I go into the city for hockey games.)

Moscow subway used to be exceptional - I don't think I am biased. Trains came and went every 70-80 seconds (at peak hours) and architecture was striking. I think it was an in your face thing that communists valued on par with the space program. Since my school and student years I have of course travelled the world and had seen quite a few subways; I remember the shock of entering the New York subway for example... Oh man. London, Paris, Sydney, Boston... Naaaaah. Nothing compares to the Moscow subway of the past. Tokyo maybe...? (I don't remember it too well)

I am not sure about now though.

It is me who is sorry for offtopic! :-)
Back to the regularly scheduled ~~drinking~~ programming...

Not my problem.

Non-polynomial system.

As far as I am aware any Boolean process can be resolved to some form of Turing Machine. NP processes such as "look-ahead strategy evaluation in GO would "probably" be more effective with a quantum computer. A possible criterion for such a device would be that it have the capacity to model all possible propagators to a specified final state. This becomes more of a mathematical exercise that is implemented within a quantum device.
Regarding P, NP, Richard Kaye's minesweeper pages are interesting.

Not sure I understand this one...

Concerning cellular, biological processes..nothing is simple. These are self-organizing living systems involving a multitude of simultaneous quantum relativistic processes. Within each molecular process there is a consistency of action, albeit not perfect, based upon some genetic interaction. If one can determine a consistent and simple atomic process underlying a genetic process and making it work as slow as possible, substitute a radioactive marker (choose your isotope), then one can detect and model a specific action. With a quantum computer capable of detecting all possible states simultaneously of such a reaction it should be possible to interact with such a system with a tunable dye laser.

...or this one.

One of my questions is, is there a "jenga-like" quality to the structure of space-time geometry. That is, if all the smallest components are the same, will removing one (or more) of these components cause it to come crashing down.
To expand on the first post, if the first of two linked quantum computers can simultaneously measure in real-time various physical parameters and have the second computer output these numerical measurements relative to a theoretical context, this kind of modelling could possibly lead to a better so-called wave-function of the universe and such a model would be better simulated within a quantum computer.

Ultimately everything must be quantifiable (like Kelvin but not like Eddington). Integer factorization regardless of magnitude should be a pencil and paper process but it isn't. Why is that?
Sorry for the lack of clarity and word choice, I'll work on it.

This is a great forum and I've learned some great coding tricks from some of the contributors. Thank you.

As Scott Aaronson says on his masthead, "Quantum computers are not known to be able to solve NP-complete problems in polynomial time". You need to have special properties in order to take advantage of the quantum speedup.

Quantum computers can't do that. See e.g.

Note, I didn't say a quantum computer could solve an NP type problem (intelligence is used to solve things and computers are tools), I stated that a quantum computer would be more effective [than a boolean architecture] for this specific game.

I'm quite ignorant of a great many things and know the bare rudiments of others. I rarely post because what I have is of little to no value but I do express an opinion now and then. There are some very interesting things taking place these days, Perelman's proof, discovery of a new boson, advances in cyber warfare..squidfarts (see 2600)..etc.
Anyways, a great topic (quantum computers) and I would really like to see such devices become commonplace during my lifetime.
Ciao.

The test of a cosmological model is whether it agrees with experiment. I have provided a model that tests the logic of several theories and models to all "N" greater than two. Shakespear gave "Let bi-gons be bi-gons." The first poly is the trigon followed "bi" the tetragon. In the test given, infinite polys produce infinite cosmologies that can be stripped down to the only things that remain constant to each entropic system. The trigon in Dia. IAM tried. The tetra in Dia. IAM squared. Penta in (you guessed it), IAM pent Dia. etc...to IAM infinite. In an entropic system of N objects exchanging momentum, the quantity of gravitational time lines as potential futures is negative N triangulated =Q.
Some girls mind their P's and Q's. Others watch their M&m's to shape their D&d's (in French of course). See the insert diagram. Some go for the pleasing surface symmetry keeping their gaze on r&R and perhaps A to some scale. None can escape the attraction of U.
Did you think these pretty values come from boys and men who merely use them without any effort put forth in attempting to account for origin or reason? If you can't find or argue your position on who is engaged with whom in this rhetorical dialog, you may accept the invitation of Lady Wisdom and find a place at the feet of Mother Nature's beloved muse and daughter who has offered her teachings as milk for all lost lambs of logic only to have her blood shed and her body consumed in every age and atomic distributional form. Or...
i. Construct a temple on a theoretical foundation.
ii. Sculpt a divinity without predicting a theoretical numerical value.
iii. When the sculpture won't fit in the temple; let a neutrino knock it's head off and crack the foundation. q.v. (CERN OPERA Super Nova)
iv. Install the remainder declaring a fait accompli knowing the results can never be independently repeated, confirmed, repudiated, amended, corrected, argued or contradicted by logic, intuition, form or formula proving it is what you say it is and does what you say it does.
v. Let future generations of eager young "Priests Forever according to the Order of Atlas and Matricide" continue to sacrifice protons and Jews on the altar of what remains of science and intellect.
vi. Lather, rinse, repeat.

...and things awaiting Santa's attention.
OOPS!
I posted in the wrong thread. Someone was asking about muses (see avatar and guess name and what she is doing) and busoms. Knowing my luck I'd get the computer with a stray isotope changing polarity in the matrix that calculates Pi to the "Feynman Point". I'd be happy it's what I asked for, more than anticipated, more than needed for practical purposes, as well as entirely predictable. Completely worthless without a brain.
