Decoherence and open quantum systems
... We start with the formulation of quantum states by density operators which will be our objects of interest throughout this work. After the definition of entanglement and the discussion of some special states, we focus on the geometry of different quantum mechanical systems. These geometrical pictur ...

Discrete Approaches to Quantum Gravity in Four Dimensions
... in theoretical physics still remains unsolved. This article contains an overview and a comprehensive bibliography of past efforts to define a consistent theory of quantum gravity in four dimensions via an intermediate discretization. I will only discuss models with some concrete implementation of th ...

Quantum Information with Fermionic Gaussian States - Max
... In this Thesis we study finite-dimensional fermionic Gaussian states and channels. In physics, Gaussian approximation is a frequently used tool for solving many-body problems. Gaussian approximation relies on describing system fully in terms of two-point correlation functions. This means that all th ...

For example, the Quantum Fourier Transform (QFT) [21], a component of Shor’s factorization algorithm [25], requires all-to-all communication. Third, the routing of qubits must be timed to coincide with the arrival of opcodes ...
