Feedback stabilization of multi-qubit Hamiltonian parameters enabled by single-shot measurement-based sequential Monte Carlo
Hyeongyu Jang, Jaemin Park, Younguk Song +6
Fast measurement, signal processing, and accurate estimation of Hamiltonian parameters are essential for feedback control in quantum-classical interface circuitry. However, existin…
Highly Tunable Two-Qubit Interactions in Si/SiGe Quantum Dots by Interchanging the Roles of Qubit-Defining Gates
Jaemin Park, Hyeongyu Jang, Hanseo Sohn +5
Silicon quantum dot spin qubits have become a promising platform for scalable quantum computing because of their small size and compatibility with industrial semiconductor manufact…
Shallow randomized measurement in noisy quantum devices
Gyungmin Cho, Dohun Kim
Quantum hardware is steadily improving, but near-term quantum devices remain limited by noise and circuit depth. This motivates measurement protocols that can use shallow-depth cir…
Application of zero-noise extrapolation-based quantum error mitigation to a silicon spin qubit
Hanseo Sohn, Jaewon Jung, Jaemin Park +5
As quantum computing advances towards practical applications, reducing errors remains a crucial frontier for developing near-term devices. Errors in the quantum gates and quantum s…
