Geometric phase distributions for open quantum systems.
In an open system, the geometric phase should be described by a distribution. We show that a geometric phase distribution for open system dynamics is in general ambiguous, but the imposition of reasonable physical constraints on the environment and its coupling with the system yields a unique geometric phase distribution that applies even for mixed states, nonunitary dynamics, and noncyclic evo...
متن کاملHybrid topological-spin qubit systems for two-qubit-spin gates
We investigate a hybrid quantum system involving spin qubits, based on the spins of electrons confined in quantum dots, and topological qubits, based on Majorana fermions. In such a system, gated control of the charge on the quantum dots allows transfer of quantum information between the spin and topological qubits, and the topological system can be used to facilitate transfer of spin qubits be...
متن کاملQuantum information transfer between topological and spin qubit systems.
We propose a method to coherently transfer quantum information, and to create entanglement, between topological qubits and conventional spin qubits. Our suggestion uses gated control to transfer an electron (spin qubit) between a quantum dot and edge Majorana modes in adjacent topological superconductors. Because of the spin polarization of the Majorana modes, the electron transfer translates s...
متن کاملOn Discrete Quasiprobability Distributions
Due to the recent development of hardware facilities, the description of the state and evolution of the wave processes has also evolved. In addition to the configuration space description and Fourier analysis, it has now become possible to use the Quasiprobability distributions that describe the state of the wave process in phase space of the corresponding mechanical system. By wave process we ...
متن کاملDensity Operators and Quasiprobability Distributions
The problem of expanding a density operator p in forms that simplify the evaluation of important classes of quantum-mechanical expectation values is studied. The weight function P(n) of the P representation, the Wigner distribution W(o), and the function (n ~ p ~o), where ~n) is a coherent state, are discussed from a unified point of view. Each of these quasiprobability distributions is examine...
