Flag fault-tolerant error correction for cyclic CSS codes
(University of Waterloo, 2018-06-20)Fault-tolerant quantum error correction (FTEC) protocol is one of the most important components for a fault-tolerant simulation of a quantum circuit. It helps prevent error accumulation during the process which may cause ... -
Flags and Error Weight Parities: A Development of Fault-tolerant Quantum Computation with Few Ancillas
(University of Waterloo, 2021-10-13)In quantum computation, errors in a quantum circuit arising from its interaction with the environment is one of the biggest obstacles to building large-scale quantum computers. One way to deal with such errors is using ... -
Noisy Embezzlement of Entanglement and Applications to Entanglement Dilution
(University of Waterloo, 2019-05-23)In this thesis we present the concept of embezzlement of entanglement, its properties, efficiency, possible generalizations and propose the linear programming characterization of this phenomenon. Then, we focus on the noisy ... -
Quantum Blind Data Compression and Structure of Quantum Operations Approximately Preserving Quantum States
(University of Waterloo, 2021-07-29)In this thesis, we investigate a variation of quantum information processing tasks, blind data compression, and we analyze an approximation of a structure of a set of quantum states closely related to the task, which is ... -
Quantum state purification
(University of Waterloo, 2016-08-29)Quantum state purification is a process in which decoherence is partially reversed by using multiple copies of the input states that have been subject to the same decoherence effect. This thesis focuses on purifying the ...
