This course will be offered starting from Sep 2021 as a Book Course (LTAT.00.015). We have found numerically an error threshold that is slightly lower for this combination of error sources than if there is no coherence in the errors. Quantum Error Correction & Fault-Tolerant Quantum Computing. ![]() QUANTUM ERROR CORRECTION SEMINAR CODEWe investigated the combined effects of coherent errors and readout errors on the surface code, using a recently introduced mapping of the surface code to Majorana fermions. Errors arising from entanglement with the environment can be investigated efficiently for the surface code, however, so-called coherent errors (resulting from 1/f noise) are harder to model. Besides computation and communication, quantum error correction can also improve the performance of quantum sensing and quantum simulation. Abstract: Quantum error correction is a powerful method for protecting a quantum system from the damaging effects of noise. Title: Quantum Error Correction for Sensing and Simulation. Professor Liang Jiang, University of Chicago Hosted by Dr. The most promising quantum error correction scheme to date, the Surface Code, uses the entanglement in topological ordered states to distribute/hide logical qubits in several physical qubits. The basic principle of quantum error correction (QEC) is to encode information into the long-range correlations of entangled quantum many-body states in. Optics and Quantum Electronics Seminar Series. Quantum error correction is a crucial step to building useful quantum computers, needed to maintain precision in deep computations in spite of having faulty components - as long as the error rate is below a threshold value. ![]() Group Seminar at MPQ in the Herbert-Walther-Lecture Hall and via zoom The surface code, for instance, can make use of the minimum-weight perfect-matching decoding algorithm to pair the defects that are measured by its stabilizers due to its underlying charge parity conservationsymmetry. Janos Asboth, Budapest University for Technology and Economics Likewise, the design of a decoding algorithm depends on the underlying physics of the quantum error-correcting code that it needs to decode. ![]()
