On quantum error-correction by classical feedback in discrete time - Gregoratti, Werner - 2004 () Citation Context ...y the author in the 80’s [3, 4, 5] has been recently applied in many contexts including state preparation [6, 7, 8], purification [9, 10], risk-sensitive control ...
The purpose of quantum error correction (QEC) is to counteract the natural tendency of a complex system to decohere. This cooperative process, which requires participation of multiple quantum and classical components, creates a special type of dissipation that removes the entropy caused by the ...
In this work, we address this challenge by combining the paradigms of dissipative quantum error correction and trapped-ion quantum information processing to a scheme for quantum error-corrected metrology. Standard error-correcting schemes entail classical apparatuses to perform measurements and feedback ope...

We implement a full QEC protocol by using real-time feedback to encode, monitor naturally occurring errors, decode and correct. As measured by full process tomography, without any post-selection, the corrected qubit lifetime is 320 microseconds, which is longer than the lifetime of any of ...
