Exact Master Equation and Non-Markovian Decoherence for Quantum Dot Quantum Computing
Matisse W. Y. Tu, Ming-Tsung Lee, Wei-Min Zhang
In this article, we report the recent progress on decoherence dynamics of electrons in quantum dot quantum computing systems using the exact master equation we derived recently bas…
Non-equilibrium theory of charge qubit decoherence in the quantum point contact measurement
Ming-Tsung Lee, Wei-Min Zhang
A non-equilibrium theory describing the charge qubit dynamics measured by a quantum point contact is developed based on Schwinger-Keldysh's approach. Using the real-time diagram te…
Decoherence induced by electron accumulation in quantum measurement of charge qubits
Ming-Tsung Lee, Wei-Min Zhang
In this paper, we study the quantum decoherence induced by accumulation of electron tunnelings during the quantum measurement of a charge qubit. The charge qubit is a single electr…
Influence of Dynamical Pauli Effect and Dynamical Symmetry Breaking to Quantum Chaos
Ming-Tsung Lee, Wei-Min Zhang, Cheng-Li Wu
In this paper, we study the influence of quantum effects to chaotic dynamics, especially the influence of Pauli effect and dynamical symmetry breaking to chaotic motions. We apply…
