Abstract: Fibonacci anyons provide the simplest possible model of non-Abelian fusion rules: [1] x [1] = [0] + [1]. We propose a conformal field theory construction of topological quantum registers based on Fibonacci anyons realized as quasiparticle excitations in the Z_3 parafermion fractional quantum Hall state. To this end, the results of Ardonne and Schoutens for the correlation function of n = 4 Fibonacci fields are extended to the case of arbitrary n (and 3 r electrons). Special attention is paid to the braiding properties of the obtained correlators. We explain in details the construction of a monodromy representation of the Artin braid group acting on n-point conformal blocks of Fibonacci anyons. For low n (up to n = 8), the matrices of braid group generators are displayed explicitly. A simple recursion formula makes it possible to extend without efforts the construction to any n. Finally, we construct N qubit computational spaces in terms of conformal blocks of 2N + 2 Fibonacci anyons.

Binet-Fibonacci Calculus and N = 2 Supersymmetric Golden Quantum Oscillator [0.0]
Binet-Fibonacci calculus, as $varphi varphi'$ - two base quantum calculus, relates Fibonacci derivative with Binet formula of Fibonacci number operator. Here we generalize this model to supersymmetric number operator and corresponding Binet formula for supersymmetric Fibonacci operator $cal F_cal N$.

We propose Fold2Seq, a novel framework for designing protein sequences conditioned on a specific target fold. We show improved or comparable performance of Fold2Seq in terms of speed, coverage, and reliability for sequence design. The unique advantages of fold-based Fold2Seq, in comparison to a structure-based deep model and RosettaDesign, become more evident on three additional real-world challenges.

Quantum Coin Flipping, Qubit Measurement and Generalized Fibonacci Numbers [0.0]
The problem of Hadamard quantum coin measurement in $n$ trials is formulated in terms of Fibonacci sequences for duplicated states, Tribonacci numbers for triplicated states and $N$-Bonacci numbers for arbitrary $N$-plicated states. For generic qubit coin, the formulas are expressed by Fibonacci and more general, $N$-Bonaccis in qubit probabilities.
