QUANTUM ERROR CORRECTION COMPREMENTARY PROFESSIONAL
Annual meeting with ordinary general meeting of the DPG and 2009 Spring meeting of the Section AMOP of the professional associations atomic physics, mass spectrometry, molecule physics, quantum optics and photonics combined with professional associations environmental physics as soon as the working groups equal opportunities, energy, information, young DPG, physics and disarmament 73. This gives new and intuitive proofs of both the noisy channel coding theorem and the asymptotic rates of both secret-key distillation and state mergingħ3. By adopting an information-theoretic approach to complementarity, we are able to construct entanglement distillation protocols which straightforwardly seek to distill amplitude and phase correlations without venturing into decoupling. We show that the decoupling-based results can be concretely established in the complementary classical information picture. However, the central results of quantum information theory established recently, such as the achievable rate of quantum communication over a noisy channel, follow a different approach termed decoupling which has a natural origin in the study of quantum cryptography.
Correcting errors afflicting either of these observables is sufficient to restore the quantum information to its original state. Since the breakthrough by Calderbank, Shor, and Steane on the existence of quantum error-correcting codes, an oft-used notion in quantum information theory is that we can treat quantum information essentially as a strange combination of two types of classical information, pertaining to two complementary observables ''amplitude'' and ''phase''.
