Robust iSWAP gates for semiconductor spin qubits with local driving
Qi-Pei Liu, Zheng-Yuan Xue
Scalable quantum computation demands high-fidelity two-qubit gates. However, decoherence and control errors are inevitable, which can decrease the quality of implemented quantum op…
NISQ Security and Complexity via Simple Classical Reasoning
Alexandru Cojocaru, Juan Garay, Qipeng Liu +1
We give novel lifting theorems for security games in the quantum random oracle model (QROM) in Noisy Intermediate-Scale Quantum (NISQ) settings such as the hybrid query model, the…
Improved Quantum Lifting by Coherent Measure-and-Reprogram
Alexandru Cojocaru, Juan Garay, Qipeng Liu +1
We give a tighter lifting theorem for security games in the quantum random oracle model. At the core of our main result lies a novel measure-and-reprogram framework that we call co…
The curious case of "XOR repetition" of monogamy-of-entanglement games
Andrea Coladangelo, Qipeng Liu, Ziyi Xie
In this work, we consider "decision" variants of a monogamy-of-entanglement game by Tomamichel, Fehr, Kaniewski, and Wehner [New Journal of Physics '13]. In its original "search" v…
Quantum Lifting for Invertible Permutations and Ideal Ciphers
Alexandru Cojocaru, Minki Hhan, Qipeng Liu +2
In this work, we derive the first lifting theorems for establishing security in the quantum random permutation and ideal cipher models. These theorems relate the success probabilit…
