   Sammanfattning : Low-Density Parity-Check (LDPC) codes are linear error-correcting codes used to establish reliable communication between units on a noisy transmission channel in mobile telecommunications. LDPC algorithms detect and recover altered or corrupted message bits using sparse parity-check matrices in order to decipher messages correctly. LÄS MER

4. 3. Impact of Noise on the Accuracy of Amplitude Amplification on the IBM Q Quantum Computer

   Kandidat-uppsats, KTH/Datavetenskap

   Författare :Dilvan Sabir; Edvard All; [2022]
   Nyckelord :;

   Sammanfattning : Quantum computers promise immense speed up compared to even the most advanced supercomputers of today, but environmental noise introduces errors in the former, constituting a significant hurdle for realizing these promises. Quantum error-correcting codes have been suggested as a strategy to alleviate this hurdle, including codes optimized toward computation under specific models of noise. LÄS MER
