The Spin Density Matrix II: Application to a system of two quantum dots
Sharif D. Kunikeev, Daniel A. Lidar
This work is a sequel to our work "The Spin Density Matrix I: General Theory and Exact Master Equations" (eprint arXiv:0708.0644 [cond-mat]). Here we compare pure- and pseudo-spin…
The Spin Density Matrix I: General Theory and Exact Master Equations
Sharif D. Kunikeev, Daniel A. Lidar
We consider a scenario where interacting electrons confined in quantum dots (QDs) are either too close to be resolved, or we do not wish to apply measurements that resolve them. Th…
Linear Quantum Error Correction
A. Shabani, D. A. Lidar
We develop a generalized theory of quantum error correction (QEC) that applies to any linear map, in particular maps that are not completely positive (CP). This theory describes en…
Non-Markovian dynamics of a qubit coupled to an Ising spin bath
Hari Krovi, Ognyan Oreshkov, Mikhail Ryazanov +1
We study the analytically solvable Ising model of a single qubit system coupled to a spin bath. The purpose of this study is to analyze and elucidate the performance of Markovian a…
Towards Fault Tolerant Adiabatic Quantum Computation
Daniel A. Lidar
I show how to protect adiabatic quantum computation (AQC) against decoherence and certain control errors, using a hybrid methodology involving dynamical decoupling, subsystem and s…
Entanglement, fidelity and topological entropy in a quantum phase transition to topological order
A. Hamma, W. Zhang, S. Haas +1
We present a numerical study of a quantum phase transition from a spin-polarized to a topologically ordered phase in a system of spin-1/2 particles on a torus. We demonstrate that…
