This seminar presents a theoretical framework that identifies when a hybrid approach provides an advantage, together with two experiments on IBM transmon processors that validate the theory. The theory derives closed-form expressions for the entanglement fidelities of competing protocols, along with a sharp criterion for hybrid advantage. The first experiment combines logical DD with an error-detecting code to produce entangled logical states with fidelities exceeding those of the corresponding unprotected physical states. The second implements a surface-code memory on heavy-hex hardware, where gap-aware DD yields basis-resolved improvements as the code is scaled from distance 3 to anisotropic distances (3,5) and (5,3). Together, these results demonstrate that carefully integrating dynamical decoupling with quantum error correction can outperform either technique alone, providing new insights into the design of scalable fault-tolerant quantum computing systems. ![](https://www.quantum-machines.co/wp-content/themes/baseline/dist/images/seminar-form/bg-section.webp)## Register Now Live Seminar | 26 August 2026 | 07:00 PM GMT+3 ## More to explore [ ![](https://www.quantum-machines.co/wp-content/uploads/2026/06/QM_0626_1680x434_Dr.-Ilai-Schwartz_seminar-InnerHero-1024x265.webp) ### First Individual Addressing of Organic Molecular Spin-Qubits for Versatile Spin-Photon Interfaces in Quantum Technologies ![Dr. Ilai Schwartz](https://www.quantum-machines.co/wp-content/uploads/2026/06/Dr.-Ilai-Schwartz-1-150x150.webp) Dr. Ilai Schwartz June 2026 View Now ](https://www.quantum-machines.co/seminars/first-individual-addressing-of-organic-molecular-spin-qubits-for-versatile-spin-photon-interfaces-in-quantum-technologies/) [ ![](https://www.quantum-machines.co/wp-content/uploads/2026/05/QM_0526_1680x434_Dr.-Madelyn-Cain_seminar-InnerHero-1024x265.webp) ### Shor’s Algorithm is Possible with as Few as 10,000 Reconfigurable Atomic Qubits ![Dr. Madelyn Cain](https://www.quantum-machines.co/wp-content/uploads/2026/06/Dr.-Madelyn-Cain-1-150x150.webp) Dr. Madelyn Cain May 2026 View Now ](https://www.quantum-machines.co/seminars/shors-algorithm-is-possible-with-as-few-as-10000-reconfigurable-atomic-qubits/) [ ![](https://www.quantum-machines.co/wp-content/uploads/2026/05/QM_0526_1680x434_seminar-InnerHero-1024x265.webp) ### Scaling a Chiplet-Based Superconducting Quantum Processor Toward Fault Tolerance ![Dr. Andrew Betswick](https://www.quantum-machines.co/wp-content/uploads/2026/06/Dr.-Andrew-Betswick-2-150x150.webp) Dr. Andrew Betswick May 2026 View Now ](https://www.quantum-machines.co/seminars/scaling-a-chiplet-based-superconducting-quantum-processor-toward-fault-tolerance/)
