20.500.12556/RUL-172852 Developing and analyzing the defect-based surface codes using optimization algorithms Fault tolerance is crucial for enabling large-scale quantum computations, with surface codes emerging as prominent error correction techniques due to their high error threshold and reliance on nearest-neighbor interactions. Despite the advantages of surface codes, they demand a substantial number of qubits to encode a single logical qubit, making them resource-intensive. Two primary approaches exist to encode multiple logical qubits: patch-based and defect-based. This study focuses on the latter approach, which involves creating holes in the surface code for logical qubit encoding. With the defect-based approach, we need to account for trade-offs between the number of logical qubits and the logical error rates, so we employ an optimization algorithm to evaluate the maximum number of logical qubits for a given error rate. Through a series of experiments, we assess the limitations of the defect-based approach and investigate the impact of various hole types on logical qubit encoding. genetic algorithms logical error rates logical qubits quantum computing quantum error correction simulated annealing surface codes genetski algoritmi stopnje logičnih napak logični kubiti kvantno računanje kvantna korekcija napak simulirano žarjenje površinske kode true false true Angleški jezik Slovenski jezik Članek v reviji 2025-09-11 14:27:32 2025-09-11 14:27:33 2025-10-25 04:09:00 0000-00-00 00:00:00 2025 0 0 23 str. iss. 2, art. 25 Vol. 7 Jun. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004 2624-960X 10.3390/quantum7020025 239228931 RAZ_Sayedsalehi_Samira_2025.pdf RAZ_Sayedsalehi_Samira_2025.pdf 1 615C1129FE220681BBA550BDB236BDBB e42116b74c12f70f2d33d2a90eb8561f0e924d8e3803b73ea6563d52c54e2b5d 2127dc16-8f0b-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=216968 https://www.mdpi.com/2624-960X/7/2/25 1 880117d6-8f0a-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=216967 Fakulteta za računalništvo in informatiko 0 0 0
