Robust high-order quantum simulation using finite-width pulses
Leeseok Kim, Milad Marvian
We present a general framework for promoting first-order pulse sequences in quantum simulation to higher-order sequences that maintain robustness in the presence of finite pulse-wi…
High-order dynamical decoupling in the weak-coupling regime
Leeseok Kim, Milad Marvian
We introduce a high-order dynamical decoupling (DD) scheme for arbitrary system-bath interactions in the weak-coupling regime. Given any decoupling group that averages…
Higher-order Zeno sequences
Kasra Rajabzadeh Dizaji, Leeseok Kim, Milad Marvian +1
The quantum Zeno effect typically refers to freezing the dynamics of a quantum system through frequent observations. In general, quantum Zeno dynamics is obtained with an error of…
Faster Randomized Dynamical Decoupling
Changhao Yi, Leeseok Kim, Milad Marvian
We present a randomized dynamical decoupling (DD) protocol that can improve the performance of any given deterministic DD, by using no more than two additional pulses. Our construc…
