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…
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…
Robustness of operator quantum error correction with respect to initialization errors
Ognyan Oreshkov
In the theory of operator quantum error correction (OQEC), the notion of correctability is defined under the assumption that states are perfectly initialized inside a particular su…
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…
Continuous quantum error correction for non-Markovian decoherence
Ognyan Oreshkov, Todd A. Brun
We study the effect of continuous quantum error correction in the case where each qubit in a codeword is subject to a general Hamiltonian interaction with an independent bath. We f…
