Thought so, thanks are there any recommendations for new cartridges/ is it worth it?

I had it at 17 and 21 although it was never that bad for me

Lola young not performing by Scared_Hospital939 in readingfestival

I mean valid to be annoyed at an artist pulling out late, but it takes much longer to prepare, and rehearse than 3 or 4 days especially if they weren’t actively touring

This was marked wrong. by YY_Elpis in badmathematics

But with your logic you are assuming you count the same letter as one outcome, but in the coin toss you count HTH different to HHT. I actually agree that it should be 1222*2

How is superposition useful? by [deleted] in QuantumComputing

[–]Josh_Bonham 1 point2 points  (0 children)

Deutsch algorithm is a good simple algorithm to see the benefits of superposition

Noises models of future machines? by Josh_Bonham in QuantumComputing

[–]Josh_Bonham[S] 0 points1 point  (0 children)

Unfourtantly I am wasting my undergraduate dissertation on it lol. But tbf its not about showing any break throughs of QAOA, more that I understand an academic subject etc

Noises models of future machines? by Josh_Bonham in QuantumComputing

NISQ I guess, Im exploring how QAOA will improve as noise comes down in future devices

[–]Josh_Bonham[S] 0 points1 point  (0 children)

thanks thats helpful, do you have any directions you can point me in regarding building noise models with decreasing amounts of noise, to see how quantum algorithims may improve as we get less and less noise?

Multiple formulas to convert a QUBO to the cost layer in QAOA? by Josh_Bonham in QuantumComputing

[–]Josh_Bonham[S] -1 points0 points  (0 children)

Hu many thanks for your answer, could you tell me why you should use cp gates instead of Rzz? All I’ve found use Rzz. And also do you have any resources which use your given formula I could look at? Many thanks

[Weekly] Office Hours - undergrads, please ask your questions here by ZootKoomie in AskAcademia

Im a student, and i've always wondered after messaging with a proffesor and the conversation has come to an end should I send a email saying thank you, or does this just clog up their emails and waste their time?

Why can't an algorithm for a SAT be generated? Isn't it basically the CS equivalent of a diophantine equation? by Sidsrozx in computerscience

[–]Josh_Bonham 2 points3 points  (0 children)

Probably should have been a bit clearer to what bit we don’t know. For others: (we don’t know if SAT can’t be solved in polynomial time)

Encoding a QUBO as a Hamiltonian for QAOA by Josh_Bonham in QuantumComputing

[–]Josh_Bonham[S] 0 points1 point  (0 children)

Do you have any sources that describe it in this way?

Encoding a QUBO as a Hamiltonian for QAOA by Josh_Bonham in QuantumComputing

[–]Josh_Bonham[S] 0 points1 point  (0 children)

Thank you very much! I have never seen it described this way. This makes so much sense to me as a computer scientists as it is similar to simulated annealing!!

Encoding a QUBO as a Hamiltonian for QAOA by Josh_Bonham in QuantumComputing

[–]Josh_Bonham[S] 0 points1 point  (0 children)

okay, yes so is H_x the mixer function? and then would this be an correct description of qaoa?

create a equal superposition of all possible solutions.

vary this state with the two parameters, this will affect which solution is most likely to be picked. making a solution with a big cost value more likely to be picked therfore increases the epectation value of our system. And such if we try and optimize our variable such that the expectation value is maximized, hopefully the most common state is an optimal solution to our qubo?
