Kardar-Parisi-Zhang dynamics in an open integrable system: beyond the spontaneous-symmetry-breaking ansatz
Guo-Qiang Wang, Chang-Ling Zou, Guang-Can Guo +1
The universality of dynamical scaling laws constitutes a cornerstone in the theoretical understanding of quantum many-body systems, particularly in non-equilibrium settings. Recent…
Magnetic-free optical mode degeneracy lifting in lithium niobate microring resonators
Xin-Biao Xu, Zheng-Xu Zhu, Yuan-Hao Yang +9
Breaking time-reversal symmetry in integrated photonics without magnetic fields remains a fundamental challenge. We demonstrate phonon-induced non-reciprocity through direct liftin…
On-chip Parametric Amplification in a Double Quantum Dots Circuit
Yong-Qiang Xu, Rui Wu, Si-Si Gu +8
In microwave-based quantum circuits, including double quantum dots (DQDs), superconducting qubits and spin qubits, parametric amplifiers are indispensable in achieving high-fidelit…
Optimal control with flag qubits
Liang-Xu Xie, Lui Zuccherelli de Paula, Weizhou Cai +6
High-fidelity quantum operations are the cornerstone of fault-tolerant quantum computation. In open quantum systems, traditional optimal control only passively resists decoherence,…
Scalable Generation of Macroscopic Fock States Exceeding 10,000 Photons
Ming Li, Weizhou Cai, Ziyue Hua +7
The scalable preparation of bosonic quantum states with macroscopic excitations poses a fundamental challenge in quantum technologies, limited by control complexity and photon-loss…
All-optical control and multiplexed readout of multiple superconducting qubits
Xiaoxuan Pan, Chuanlong Ma, Jia-Qi Wang +12
Superconducting quantum circuits operate at millikelvin temperatures, typically requiring independent microwave cables for each qubit for connecting room-temperature control and re…
