Operator quantum error correction for continuous dynamics
Ognyan Oreshkov, Daniel A. Lidar, Todd A. Brun
We study the conditions under which a subsystem code is correctable in the presence of noise that results from continuous dynamics. We consider the case of Markovian dynamics as we…
Optimal Dynamical Decoherence Control of a Qubit
Goren Gordon, Gershon Kurizki, Daniel A. Lidar
A theory of dynamical control by modulation for optimal decoherence reduction is developed. It is based on the non-Markovian Euler-Lagrange equation for the energy-constrained fiel…

Rigorous Bounds on the Performance of a Hybrid Dynamical Decoupling-Quantum Computing Scheme
K. Khodjasteh, D. A. Lidar
We study dynamical decoupling in a multi-qubit setting, where it is combined with quantum logic gates. This is illustrated in terms of computation using Heisenberg interactions onl…
Distance Bounds on Quantum Dynamics
D. A. Lidar, P. Zanardi, K. Khodjasteh
We derive rigorous upper bounds on the distance between quantum states in an open system setting, in terms of the operator norm between the Hamiltonians describing their evolution.…
Encoding One Logical Qubit Into Six Physical Qubits
Bilal Shaw, Mark M. Wilde, Ognyan Oreshkov +2
We discuss two methods to encode one qubit into six physical qubits. Each of our two examples corrects an arbitrary single-qubit error. Our first example is a degenerate six-qubit…
