WebA conjecture is a statement that has not been proved. The mathematician stating the conjecture is only stating that they guess it might be true. But they don’t have a proof. If … WebOct 18, 2024 · 2. I'm starting to study Turing machines, the Church-Turing conjecture and the circuit model. In particular, I'm interested in the proofs of universality that one can find in this context. So far, I have only found the universality proof of the circuit model for boolean functions (i.e., the gates AND, OR and NOT can be used to compute any ...
WebThe complexity of ground states of local Hamiltonians is the quantum analog of the theory of NP-Completeness. It features the two most important open questions in quantum complexity theory: the quantum PCP conjecture and the Area Law for 2D gapped Hamiltonians. Recent progress on the first question has been a direct consequence of the discovery of …
