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…
