Hello Professor, my question is how can we formulate the Lagrangian ? Here, we have just checked that our guess is verified and another question is that why we include Ic in that equation?
@quantum_computing
@quantum_computing Ай бұрын
Yes, it is usually based on intellectual guess (to get the K.E. and P.E. parts). Lagrangian is not unique. There are also some procedures you can follow for complicated circuits (see this paper arxiv.org/pdf/1610.03438). For Ic, it is the critical current of a JJ. We are doing KCL and thus its current (= Ic sin(phase)) needs to be included. Thanks!

But what I am unsure of is if the calibration kits come from probe station manufacturers or VNA manufacturers. I can see you are using a Keysight with a Lakeshore probe station; my guess will be that the same calibration kit works for any VNA on the same probe station.

A lot of guys commented here from each of you I wanna know and specially from professor also that up to now what I observed/analysed that currently there is all most way less to negligible application of this new theoretical framework which is quantum computing. But yes I have seen some places where quantum inspired algorithms which actually runs on classical hardware is practically useful and also industry is using but it's also very limited because of the design of this theoretical framework or may be some what different but again it's not completely quantum because it's does not runs on Quantum computer just using it's fancy and well designed mathematics. And again there is also one more concern performance which is not even better than classical in some cases which this field claim to be better.I am just skeptical, just try to question so that I feel motivated in this field and also if possible going to motivate some one even if it's just getting backlash because of all these things. Means I just want to know opinions from you people what you found insightful and interesting and as well in which specific area of research you people are to exploit the usage of this technology.

There are still a lot of issues to be solved. But at this moment, they are not impossible to be solved. Therefore, it is still promising. One cannot always predict what will happen to a technology. In the 1950s, silicon was not as promising as vacuum tubes or even germanium. But turns out it was the winner. What I tell my students is that there are a lot of intersections between traditional EE and QC. You can try to learn both at the same time.

I liked the explanation, but how does a nonlinear oscillator exhibit atom(artificial) characteristics? While we can observe the energy states of an atom and its model, how does a nonlinear oscillator physically demonstrate the same phenomena, such as electron excitation or the absorption and emission of photons?
@quantum_computing
@quantum_computing Ай бұрын
I probably cannot explain this well. But the nonlinearity comes from the Hamiltonian. For atoms, its Hamiltonian does not remember that of a simple harmonic oscillator and thus it has uneven spacings. The nonlinearity in JJ also makes the oscillator no longer remember an SHO as if it doesn't follow Hooke's law anymore (with non-linear dependence on displacement).

Considering the technology node..ReRAM is now at 28 nm, which would be much bigger than the access transistor itself in the crossbar. Moreover won't using an access transistor for each memristor increase the static power consumption and also increase in area ?...As I see these accelerators are made to function as a supplement to the main CPU in die.

Generally what type of transistors are used for the 1T1R configuration ?....I see NVIDIA transitioning from FinFET to GAA etc.. Is there any data on which transistor (MOS, BJT ,FinFET ,GAA etc..) works best with the memristor, as a selector?
@quantum_computing
@quantum_computing Ай бұрын
That depends on the technology it uses to implement the array. Usually, it is not BJT. Most of the publications are planar MOSFET e.g. 28nm. Definitely, they can use FinFET and GAA. Probably no one has tried GAA yet as it is too advanced to integrate with ReRAM at this moment. I am not sure. But in the future, for a high level of integration, yes, GAA is good.

hi, can I have solution manual to the problems of ex of this book? A solution book is given in your github repo, but sometimes I am getting confused with few solution. For eg, in ques 8.2, we have to find projection operators of eigen states of sigmaz. Eigen states of sigmaz are (1,0) and (0,1) column vectors. So projections should be row(1,0)*column(1,0) and another similar for (0,1). But solution shows multiplying sigmaz with itself. Again sigmaz is a matrix, not a vector. I dont know why this was used inside bra ket notation. This is just one eg, there are many other as well.

i see from the diode accessed crossbar structure that the input voltage (from the wordline) is applied to the diode, but in the left bottom example at 17:04, I can see that the voltage is being applied at the ReRAM terminal, why is that so ?
@quantum_computing
@quantum_computing 2 ай бұрын
The analysis in the bottom left gives the same result whether we put 5V to the left or to the right because only the potential drop across them matters as the anode and cathode of the ReRAM were not identified. So I was not rigorously trying to map to the circuit on the right. I also forgot if we had mentioned that the wordline needs to have 5V in the right figure. But you can be more rigorous and should get the same result.

at 8:16 why and how is the voltage across the diode 2.1 V ?
@quantum_computing
@quantum_computing 2 ай бұрын
I put 2.1V first because I assume the diode is almost off at 2V but turned on after 2V. Therefore, it will have a potential drop of about 2.1V (just a guessed number). It cannot be smaller than 2V because at that time the diode is off so it will take most of the voltage. It cannot be much more than 2.1V because it is turned on so it cannot take much more voltage by KVL.

You mentioned that aligning the spin with the magnetic field would yield a higher energy. But H = - µ·B --> µ = γS --> H = -γS·B, as B is defined downwards --> B = -B_0 k̂ Therefore, H = -γ (S· (-B_0 k̂ )) = γ · B_0 · S_z = γ · B_0 · (ℏ/2) · σ_z This would give that the spin up state would be higher in energy with eigenvalues of + (𝛾B_0) (ℏ/2), while the spin down state has energy of - (𝛾B_0) (ℏ/2). Did I go wrong somewhere? If yes, please let me know. Thank you for the great video by the way!
@quantum_computing
@quantum_computing 2 ай бұрын
I try not to take the risk of misunderstanding your equations so I will only explain what I meant. If the spin is in the direction of the magnetic field, its magnetic moment is in the opposite direction (so gamma is negative in your equations). That's why you get a positive H in your first equation. And it has a higher energy. Does that make sense now? Thanks!
