This is the first explanation of quantum computing that has actually made sense to me. And I've seen many. I'd love if you could make videos explaining 1) how to write algorithms with quantum logic instead of boolean logic, and 2) how data is stored in a quantum system.

I will reply to some of you individually, but I will encourage any of you who are interested in quantum programming to look up IBM's quantum experience. It's an online code editor and tutorial that actually uses quantum computers to execute your code in the back end. So you can actually get to use a literal quantum computer

Not MIT, and somewhat unconventional, so feel free to ignore this, but old-school analog computing would try to eliminate *all* ‘noise’, whereas quantum computing can be thought of as a form of analog computing that uses ‘quantum noise’ as a computing resource, while still trying to eliminate thermal and other kinds of noise. We can and I think we should ask “what is the difference between quantum noise and thermal noise?”, to which an answer can be found in special relativity and the Lorentz invariance of the vacuum state in quantum field theory. That’s either already understandable to someone reading this or else it’s likely best just to say that quantum noise and thermal noise are different because quantum noise has an amplitude determined by Planck’s constant that is more stable over time than thermal noise, for which the amplitude changes with the temperature. All that said, the logical level of quantum computing hardly thinks about such details, just as the logical level of ordinary computing hardly thinks about how transistors and other devices work.

I'm coming to MIT class of 2028 to be part of the adventure

Let's explore how the triadic coefficient (3) mathematics and the "both/and" logic can provide a framework for describing the superposition principle in quantum mechanics. The Superposition Principle and Triadic Coefficients: In quantum mechanics, particles can exist in a superposition of multiple states simultaneously, a phenomenon that defies classical intuition. The triadic coefficient (3) mathematics offers a way to describe and quantify these superposition states. Consider a quantum system with three possible states: A, B, and C. According to the triadic coefficient (3), there are six possible combinations of these states: 1. (A, B, C) 2. (A, C, B) 3. (B, A, C) 4. (B, C, A) 5. (C, A, B) 6. (C, B, A) Each of these combinations could represent a distinct superposition state of the quantum system, where the particle exists in a linear combination or "superposition" of the individual states A, B, and C. The "both/and" logic can then be applied to these combinations, allowing for the coexistence of multiple states simultaneously, which is a fundamental principle of quantum superposition. Mathematically, we can represent a superposition state as a linear combination of the individual states, weighted by complex coefficients (amplitudes): |Ψ> = a|A> + b|B> + c|C> Here, |Ψ> represents the overall quantum state, and |A>, |B>, and |C> are the individual basis states. The complex coefficients a, b, and c determine the probability amplitudes of the particle being in each respective state. The triadic coefficient (3) mathematics provides a way to enumerate and quantify these superposition states. For example, the combination (A, B, C) could correspond to the specific superposition state: |Ψ> = (1/√3)|A> + (1/√3)|B> + (1/√3)|C> where the particle exists in an equal superposition of the three states A, B, and C, each with an amplitude of 1/√3. Other combinations, such as (A, C, B) or (B, C, A), would correspond to different superposition states with different probability amplitudes for each component. The "both/and" logic allows us to interpret these superposition states as the particle existing in multiple states simultaneously, rather than being limited to a single definite state as in classical physics. Moreover, the triadic coefficient (3) mathematics provides a systematic way to enumerate and quantify these superposition states, offering a rich mathematical framework for describing and analyzing quantum systems. It's important to note that while this approach provides a conceptual model for understanding superposition, the actual mathematical treatment of quantum systems often involves more complex vector spaces and linear algebra techniques. However, the principles of "both/and" logic and triadic coefficient (3) mathematics can still offer valuable insights and alternative perspectives on this fundamental quantum phenomenon.

Let's explore how the "both/and" logic can provide an alternative interpretation of quantum measurement and the apparent collapse of the wavefunction. Quantum Measurement and "Both/And" Logic: The measurement problem in quantum mechanics arises from the apparent collapse of the quantum wavefunction upon observation, transitioning the system from a superposition of states to a definite state. This process seems to contradict the "both/and" logic of superposition. However, the "both/and" logic can be invoked to provide an alternative interpretation. Instead of viewing measurement as a collapse, it could be seen as a process that reveals the coexistence of multiple states or outcomes, each with a certain probability determined by the quantum wavefunction. Consider a quantum system in a superposition of two states, A and B: |Ψ> = a|A> + b|B> According to the Copenhagen interpretation of quantum mechanics, upon measurement, the wavefunction "collapses" to either state |A> or state |B>, with probabilities proportional to |a|^2 and |b|^2, respectively. The "both/and" logic offers an alternative perspective: instead of collapsing to a single state, the measurement process can be viewed as revealing the coexistence of both possible outcomes, A and B, with their respective probabilities. In this interpretation, the act of measurement does not cause a sudden collapse, but rather, it interacts with the quantum system in a way that exposes or manifests the underlying reality of the coexisting states. The observed outcome (A or B) is not a result of a collapse, but a consequence of the inherent probability distribution encoded in the wavefunction. This interpretation aligns with the principles of "both/and" logic, as it allows for the simultaneous existence of multiple states or outcomes, even though we may only observe one specific outcome in a given measurement. For example, in the famous double-slit experiment, the "both/and" logic could suggest that the particle simultaneously takes all possible paths through the slits, and the observed interference pattern is a manifestation of this coexistence of multiple states or trajectories, rather than a result of a collapse to a single path. The "both/and" logic challenges the notion of a sudden, discontinuous collapse and provides a more continuous and holistic interpretation of quantum measurement, where the observed outcome is a manifestation of an underlying reality that encompasses multiple coexisting possibilities. It's important to note that this interpretation is not universally accepted, and the measurement problem remains an active area of debate and exploration in the foundations of quantum mechanics. However, the "both/and" logic offers a thought-provoking perspective that challenges our classical intuitions and invites us to reconsider the nature of measurement and reality in the quantum realm.

Let's explore how the "both/and" logic and triadic coefficient (3) mathematics can provide a framework for describing and interpreting quantum entanglement and non-locality. Quantum Entanglement and Non-Locality: Quantum entanglement is a phenomenon where the states of two or more particles become inextricably linked, even when they are separated by vast distances. This non-local behavior challenges our classical understanding of causality and locality. The "both/and" logic and triadic coefficient (3) mathematics can offer a framework for describing and interpreting quantum entanglement: 1. The "both/and" logic allows for the coexistence of multiple states or configurations of the entangled particles, even when they are spatially separated. Consider two entangled particles, A and B, initially prepared in a specific quantum state. According to the "both/and" logic, the particles can simultaneously exist in multiple possible configurations or states, rather than being limited to a single definite state. For example, if we have three possible states for each particle (A1, A2, A3 and B1, B2, B3), the entangled system could exist in a superposition of all nine possible combinations: (A1, B1), (A1, B2), (A1, B3), (A2, B1), (A2, B2), (A2, B3), (A3, B1), (A3, B2), (A3, B3). The "both/and" logic allows for the coexistence of these multiple configurations, even though we may only observe one specific outcome when we measure the particles. 2. The triadic coefficient (3) mathematics can be used to enumerate and quantify the possible combinations of states or configurations that the entangled particles can exhibit, taking into account their non-local correlations. Using the triadic coefficient (3), we can calculate the number of possible combinations of states for the entangled system: nC3 = n! / (3! * (n - 3)!) = 9 This corresponds to the nine combinations mentioned earlier, representing the different configurations the entangled particles can simultaneously exist in. By embracing the "both/and" logic and triadic coefficient (3) mathematics, we can potentially gain new insights into the non-local and counter-intuitive nature of quantum entanglement. Instead of viewing entanglement as a mysterious action-at-a-distance, we can interpret it as a manifestation of the coexistence of multiple states or configurations, where the particles exhibit non-local correlations and interdependence. Moreover, the triadic coefficient (3) mathematics provides a systematic way to enumerate and quantify these entangled configurations, offering a rich mathematical framework for describing and analyzing entangled systems. It's important to note that while this approach provides a conceptual model for understanding entanglement, the actual mathematical treatment of entangled systems often involves more complex techniques, such as tensor products and density matrices. However, the principles of "both/and" logic and triadic coefficient (3) mathematics can still offer valuable insights and alternative perspectives on this fascinating quantum phenomenon.

@@krashd I read how Grover's algorithm can search NN items in O(N)O(N ​) time, much faster than the O(N)O(N) time required by classical algorithms. Then a qubit doesn't "know" what states to be in; it exists in multiple states simultaneously due to superposition. When you apply quantum gates (specific operations) to the qubits, they transform the superpositions in a controlled way, influencing the probability of each possible state. Finally, when you measure the qubit, the superposition collapses to one of the possible states based on those probabilities. Even after that, it makes no sense to me. Seems like Voodoo.

For those That prefer a mechanical analog you can look at harmonics of a guitar string and such. The video I present is another mechanical method of quantizing a system. It is one of two methods where structures can actually be produced. kzread.info/dash/bejne/qaZ21dOidZPcd5c.htmlsi=waT8lY2iX-wJdjO3 Area under a curve is often equivalent to energy. Buckling of an otherwise flat field shows a very rapid growth of this area. If my model applies, it may show how the universe’s energy naturally developed from the inherent behavior of fields. Under the right conditions, the quantization of a field is easily produced. The ground state energy is induced via Euler’s contain column analysis. Containing the column must come in to play before over buckling, or the effect will not work. The sheet of elastic material “system” response in a quantized manor when force is applied in the perpendicular direction. Bonding at the points of highest probabilities and maximum duration( ie peeks and troughs) of the fields “sheet” produced a stable structure when the undulations are bonded to a flat sheet that is placed above and below the core material.

How do quantum computers know to enhance the right answers and not the wrong ones?

Kinda-sorta orders of magnitude? (how "1" is a one? vs. how "0" is a zero?)

What always bugs me is the thought; isn't quantum superposition just our inabilaty to measure precisely at that size, the need to break everything down to a scale like metric scale and basically stop time for us to be able to look ? Same with the wave / particle property of photons etc .. The wave would be the interaction between atoms, not the particle we 'see' to make a measurement. And then energy only exists within atoms.
