Suppose you were given \sum_{i=0}^{2^n}\left| i\right>\left| f(i)\right>, is there something you can do so that when you measure in the computational basis, you have a large chance of getting a particular desired \left| i\right>\left| f(i)\right>?

hi everyone, I have recently started studying abvout control engineering, but am not getting a grasp on the basic idea behind controls. All the textbooks say that the output should track the input ideally , but why is it so? i.e if i give a step input to a system, the response should ideally...

Is there a device that can read the positions of pixels on a monitor, may be just 6 key positions and give a real time output?

can anyone tell me how to solve for the voltage output in a generator and all the variables needed to solve it. What if I only have the RPM can I solve it? thanks

Several people (I think Arivero was one) have shown an interest in data on recent string publication and the question of how properly to interpret it----which basically comes down to whether you can predict. In sampling the string publication rate, we've never used this exact set of keywords. I...

Homework Statement I am asked to plan a practical to determine the power output of a solar cell, i.e how much light energy is converted toe electrical energy per second. Now I thought(obviously) to just connect voltmeter across it with an ammeter and use PVI, however thinking about it, I don't...

Im having some trouble interpreting the MCNP output file, more specificaly table 140 that describes reaction rates. The problem of course is that the acctual reaction rates isn't written but rather things like total colissions, collions*weight, weight lost to capture etc. How do I convert...

Hi, I need with the following question. Argon gas expands in an adiabatic turbine from 3MPa and 750 C to .2 MPa at a rate of 5 kg/s. Neglect KE and PE effects. Find maximum power output. I know I need to first find the temperature of state two and then use that to solve for h2 (I have...

Obviously life on Earth must get energy from the Sun. But MOST of the Suns energy must be radiating out into space, pretty much "wasted" from our perspective. So, my question is, about how much energy do you figure the sun produces per second? What sort of things on Earth could be powered...

A causal LTI filter has the frequency response H(jw) shown in the graph. For each of these input signals, determine the filtered output signal y(t). 1) x(t)=exp(jt) 2) x(t)=(sin(wt))u(t) 3) X(jw)= 1 / ((jw)(6+jw)) 4) X(jw)= 1 / (2+jw) I don't understand what I have to do to find...

What I need is that when a certain key (on a keypad) is pressed it would output a corresponding binary number. I have completed this with an HC11 in assembly language. My professor says that the HC11 is over kill and that a micro pic would do this for little money. I am new to micro pics and...
