Yoon-Ho Kim: Protecting Entanglement from Decoherence via Weak Measurement and Quantum Measurement Reversal

Yoon-Ho Kim, Pohang University of Science & Technology

Abstract

Decoherence, which causes degradation of entanglement and in some cases entanglement sudden death, is a critical problem in quantum information. Protecting entanglement from decoherence, therefore, is essential in practical realization of quantum computing and quantum communication protocols. In this talk, I will describe our recent work on protecting entanglement from amplitude damping decoherence via weak measurement and quantum measurement reversal.
