Abstract:
The present disclosure relates to a method comprising: providing a quantum register comprising a set of qubits defining a quantum system. The states of a computational basis of the quantum system may be represented by an ordered set of consecutive nonnegative integer numbers, referred to as a set of indexes. A random variable may be determined in accordance with a predefined classical-quantum format, wherein the random variable is valued in a finite domain of classical values such that each value of the domain is derived from a respective index of the set of indexes through an affine relationship, the affine relationship being defined by a scaling factor and an offset factor. The set of qubits may be encoded such that the probability of measuring a state of the quantum system in the computational basis is the probability of observing the domain value associated with the index representing said measured state when sampling the random variable.

Abstract:
The object of the invention is a method for extracting, with high yield, phycobiliproteins from cyanobacterial and/or algal biomass, obtaining extracts in water or aqueous solutions characterised by high pigment concentration and a purity degree equal to or greater than the food/cosmetic grade (P≥2). The method is based on a process characterised by a step of breaking down the cyanobacterial/algal cells by ultrasonication in an aqueous solution of ammonium sulphate, and simultaneous extraction of water-soluble compounds other than phycobiliproteins, followed by an extraction step of the phycobiliproteins using water or aqueous solutions.
