Quasiprobability distributions associated to quantum states play the same role as the probability distribution functions in classical statistical physics, but with a key difference that quantum counterparts can take negative values for some states. Due to this fact, all states are divided into classes, the first one comprised of the "classical states", whose quasiprobability distributions are...
Quantum computing performance depends on the properties of the underlying physical qubits. The depth of an algorithm is limited by the decoherence of the qubits. In this respect the design of algorithms that quantify the decoherence of qubits is particularly of interest. In order to fit the data qubit models are necessary. We present the performance of our SU2 C++ package for polymorphically...
The physical concept of elementary and composite systems forms the pillar on which our understanding of quantum phenomena stands. The present talk aims to discuss a complementary character of the description of elementary and composite finite-dimensional quantum systems within the modern phase-space formulation of quantum mechanics.
We will give a generic method of constructing the...
The paper simulates the process of the entanglement states transferring along a chain of tryptophans a) into cell's microtubule, b) connected by dipole-dipole interaction. In the work the conditions under which the migration of the entanglement states in the microtubule is possible are obtained.
The results of the work allow us to talk about the signal function of microtubule tryptophans...

When considering quantum systems in phase space, the Wigner function is used as a function of quasidensity of probabilities. Finding the Wigner function is related to the calculation of the Fourier transform from a certain composition of wave functions of the corresponding quantum system. As a rule, knowledge of the Wigner function is not the ultimate goal, and calculations of mean values of...
