- TITLE
- [GS_C_QT] Quantum Utility on IBM_Yonsei before the Fault-Tolerant Quantum Computing Era
- ABSTRACT
- In recent years, unprecedented advancements in quantum computing have occurred, involving both quantum hardware and quantum algorithms. However, demonstrating a comprehensive, significant, and precisely measurable quantum advantage over classical systems remains a formidable challenge, especially when tackling problems of practical relevance. One of the most challenging obstacles is the quantum noise originating from quantum devices. To overcome this, many quantum error correction (QEC) methods have been developed, and several roadmaps to fault-tolerant quantum computing (FTQC), for which QEC is crucial, have been suggested. Even with an optimistic outlook, an early FTQC with a millionth logical error rate (LER), that needs 1457 physical qubits (distance 27 surface code), may be available by 2030. This shows that reaching FTQC, even the early FTQC era, is quite demanding, despite rapid advances in quantum computing and considering current in-service quantum computers have less than 200 physical qubits. Therefore, it is essential to maximize the efficiency of today’s noisy quantum computers in the pre-FTQC phase and the early FTQC systems. This talk explores various approaches, including quantum error mitigation (QEM) techniques and quantum algorithms, to achieve quantum utility in the pre-FTQC era and during the early stages of fault-tolerant quantum computing. In particular, it will highlight recent advancements toward quantum utility on IBM_Yonsei, IBM’s 127-qubit Eagle r3 superconducting quantum processor.
