boltzmann grid implementation suggestion from search engine

 yep for a moment i thought how can one implement a boltzmann grid then searched in search engine google and among ideas this one seemed implementable:


Superconducting Quantum Flux Parametrons (QFPs) can implement Boltzmann grid logic—a stochastic artificial neural network—by acting as probabilistic neurons where the direction of a circulating current (
) represents the binary state (
, or "0"/"1"). These devices are highly suitable for Boltzmann machines due to their low-power consumption and adiabatic switching capabilities, allowing for stochastic operation through thermal fluctuations at cryogenic temperatures.
Core Concepts for Implementation
  • QFP as a Stochastic Neuron: A QFP consists of an inner loop and a main loop with Josephson junctions. An excitation current (
    ) causes the potential of the QFP to change from a single-well to a double-well. The state of the neuron is decided by which of the two energy-stable states the flux falls into, which can be influenced by thermal noise, acting as a stochastic binary model.
  • Boltzmann Grid Logic Structure: The system connects QFPs in a grid pattern. The "energy" of the network is defined by coupling weights (
    ) between neurons (
    ) and external biases (
    ) applied to neurons.
  • Magnetic Coupling (Synapses): Weights are implemented by magnetically coupling the main loops of adjacent QFPs. A coupling current or transformer structure controls the weight, determining whether neighboring QFPs prefer to align or misalign their magnetic flux.
Steps to Implement Boltzmann Grid Logic with QFPs
  1. Circuit Design (QFP Neurons): Design QFP cells using superconducting materials (e.g., Niobium) and Josephson Junctions (JJs). A common design includes an inner loop (
    ) and a main loop (
    ).
  2. Define Synaptic Weights (Coupling): Connect the main loops of QFP nodes using mutual inductances (
    ) to represent synaptic weights (
    ). The mutual inductance determines how one neuron's state influences another's.
  3. Embed Logic Operations: Specific logic operations (like NOR, OR, AND) are embedded by configuring the magnetic couplings (
    ) and bias currents (
    ) to set specific energy-stable states. For example, a NOR gate can be designed using three coupled QFPs.
  4. Excitation Strategy (Adiabatic Bias): Apply an AC adiabatic bias current (
    ) to the QFP to allow it to switch slowly enough that it can absorb heat and operate in a thermal-equilibrium manner, providing stochastic functionality.
  5. State Optimization (Training): Utilize maximum likelihood estimation (MLE) to optimize the bias currents (
    ) to compensate for unintended external noise and manufacturing variations, ensuring the hardware maps correctly to the mathematical Boltzmann machine model.
Advantages
  • Extreme Energy Efficiency: QFPs operate below the Landauer limit of energy dissipation.
  • High Scalability: Due to low power, a large number of QFP nodes can be packed together to form dense grid structures.
  • Stochasticity: The intrinsic double-well potential allows the QFP to function as a naturally stochastic neuron

 


---i think one can then define some programmable complexity where multiple layers or boltzmann grids are connected to each other to engineer program latticization. e.g.  surely hull design concept could been engineerable based on tested theorems by this.


so in physics lab to develop, i would need to test multiverse ideas to invent warp with such above grids.   


e.g. hull that leviates -> i think it would be the easiest to implement engineering thingy there with such method.  i mean compared to faster than light or such concepts of engineering atilgan tech challenges.

disgusting terrsts of foreign gypsies foreign terrorst grp/cult

hey later recently if not misdetection due to ptsd, the insanely maniac sociopath psycho terror cell of gypsies foreign terrst grp attempted very disgusting stage 8 type type1/type 2 terror types.   in the metaphoric novel -> the criminal space ship would do deceit and would forcefully kidnap people to its spaceship and force them to work there with saying they themselves assigned signed for working in the space ship and they are members to. this gypsie foreign terrst grp attempts same method but metaphoric version. they use force of fraud (scripted theahtric monologuye fraud method )in trying to kidnap people  to its criminal cartel this attacker foreign terrst grp. e.g. if they forcefully try to make a member they do fraud method of shouting slanders to the person slander type they forcefully try to convert to with such monologue fraud method.  (which of course they never succeed anyn atttempt of neither type 1 nor type 2 terror types)  they could of course...

 hmm i think quantum error correcting news i saw seems correct as because you can possibly reduce the measurment effect's side effect to equation with reducing its factor out.  i dont think there is something like decoherence at all i mean of course a qubit could decohere but its default existnece is actually in its universe thread superposition. its that when it decoheres its the moment its thread is on an alternate thread.  and but the original thread also exists.  so reason why alternate thread is because due to possibly entropy principles. but again, you can assure that does happen very low frequently with setting up additional bits around   qubits thats strengthen its thread condition that you compute in such thread version still. so error correction means making the compute happening thread stay in same thread. and thats possible to strengthen it mathematically (aka error correction by design of thread stability of compute universe) yep as soon as...

so today's thoughts: -> yep guh's wishful thinking alike be that, most possibly it were a coincidence but  guh daydreamt that she has chance of finding a job at army although had not graduated from army college before. (army allocates people from its colleges) but still when seeing an army person in a place, I daydreamt of finding a job at army here whilst I hadnt graduated any from army college.  if that happens it would have been totally amazing/awesome! (yep possibly guh would have worked at aliens burau at army and multiverse tech r&d at our army)  how cool it would have been to wear army uniform! :) lets check if terrorst attempts terror crime attacks to guh afterwards:)  i dont think so.  :)  so if there is chance of finding a job at our army, guh very wishes to apply to(actually i investigated also  before to see that it requires graduated from military college which i hadnt). but i also know that it requires finishing military college....
