O.K. here's the deal, a friend and I are taking a physics teaching methods course as an elective, as a part of the requirement we were asked to plan and execute (teach) a one hour lab on kinematics ( specifically ballistic movement), the Tracker program and error estimation. We decided on...

Thanks for the help, but in the case of the Darwin term it's given by some constant times a delta function, how am I supposed to get the operator form of this expression? another example is the spin-orbital interaction, it's given by 1/r^3 times some constant time the angular momentum operator...

Given a Hamiltonian in the position representation how do I represent it in operator form? for example I was asked to calculate the expectancy of the Darwin correction to the Hydrogen Hamiltonian given some eigenstate (I think it was |2,1> or something bu that doesn't matter right now), now I...

Thanks for the replies everyone, here's the deal though, I'm working on a system that would need to sit in a remote location and will contain sensitive enough files that we'd rather have it offline, meaning that google drive and one drive aren't really an option. A further explanation of the...

I have a system of 3 PCs all connected to the same router, I need some way to automatically move files from two PCs to the third, how do I even begin to approach this?

I might've not communicated it clearly, but I haven't taken any major projects, I'm taking one this semester and it's a big one, but I cannot include it yet... I'm sure enough of my abilities and I know I can pass an interview, I need to pass HR which do screen by grades seeing that the...

So I'm a fourth year EE & Physics student without a previous work experience and unfortunately with bad grades, currently I'm sitting on a 76 average, the thing is that my first year was rough and that's where most of my bad grades are, which are mostly mathematics courses, otherwise I have...

I've just read an article (link to the discussed paper at the end) talking about a newly proposed Maxwell's demon where they use a quantum measurement to extract energy from the system, which made me think, isn't energy conserved in QM as well (at least in the average sense)? and seeing that a...

I'm answering from my phone so sorry for the lack of formatting, anyway I think you're looking at it from the wrong perspective, in the example of the particle spinning both up and down you are correct to say that if we measure the spin along the up or down direction it will turn up to be either...

If I'm understanding correctly, you're asking why the cat inside the box isn't measured while a cat outside of the box is? you might want to wait for other users as I'm not an expert (understatement of the year...) but the Idea is that measurement is a physical process ,i.e. it's driven by a...

I wonder if anyone can explain how to actually synthesis a quantum circuit, what I mean by this is that given some requirements, I am able to write the matrix form of the circuit needed, but I have no idea how to turn that into a list of gates. For example: Build a circuit that performs the...

I actually know what entanglement is, my main problem is that I'm used to working with operators on the whole system so when I was told that I need to calculate a probability on a subsystem I was taken aback. My thought process is that I should sum over all possible states for the first part of...

just to make sure, if I've got a system of 2 qubits (let's say ## |\psi \rangle = \frac 1 \sqrt(2) (|00\rangle + |11\rangle ) ## ) and I want to check what's the probability of measuring the second qubit to be a ## |0\rangle ## I"ll be checking $$ \langle \psi | \sum_i |i\rangle\langle i|...

This is a rather basic question but I seem to be stuck, given a system made up of two subsystems how do I compute the probability of subsystem B to be in some state (for example I've got |p>=|a>|b> if I measure the second part what's the probability of it being found in state |c>, how am I...

Thanks for the reply! I was going for something similar, thing is my dataset is dynamic which means my maximum will change in real time, I suppose the easy solution is to always output the last 8 bits, am I correct?
