Memory dimension detection in open quantum dynamics via pseudo-control
Chang Liu, Alexander Yosifov, Ximing Wang +2
Characterising open quantum dynamics requires identifying the environmental degrees of freedom that shape the system's evolution. The memory dimension, defined as the size of the s…
Can Chemically Inspired Parameter Initialization Mitigate Barren Plateaus in Variational Quantum Eigensolvers?
Zhangyu Yang, Jinzhao Sun, Jianpeng Chen +2
Recent advances in the variational quantum eigensolver (VQE) have strengthened its promise for molecular electronic-structure calculations on near-term noisy intermediate-scale qua…
Low-cost algorithm-to-execution framework for surface-code quantum computing
Yunxin Tang, Zixuan Huo, Junxiang Huang +14
Fault-tolerant quantum computing is progressing from demonstrations of individual logical components toward the execution of useful quantum algorithms on large-scale error-correcte…
Distributed Trotterization with optimal time-scaling entanglement cost
Tianfeng Feng, Jinzhao Sun, Yunlong Xiao +1
Distributed architectures extend quantum simulation of many-body dynamics beyond the reach of any single processor, with shared entanglement mediating interactions between spatiall…
Trotter error compensation with polylogarithmic precision and nested-commutator scaling without ancillas
Xinzhao Wang, Shuo Zhou, Ziruo Wang +5
Product formulas are among the most practical approaches to Hamiltonian simulation, requiring no ancillary qubits and exhibiting error bounds governed by nested commutators rather…
Quantum-classical crossover in fault-tolerant quantum dynamics simulation
Jinzhao Sun, Bozhen Zhou, Jue Xu +28
While quantum computers promise to solve classically intractable problems, identifying the point at which fault-tolerant quantum computation outperforms the best classical algorith…
Quantum probe advantage in learning many-body systems
Wenzheng Dong, Andrew G. Green, Vlatko Vedral +1
Which properties of a quantum many-body system are operationally accessible is a central question underlying spectroscopy, thermodynamics, and quantum information science. Conventi…
Entanglement-facilitated macroscopic cluster formation in quantum many-body dynamics
Xiao Wang, Alexander Yosifov, Aditya Iyer +1
Metastable quantum many-body dynamics could facilitate the organisation of microscopic degrees of freedom into macroscopic structures. However, the conditions under which this occu…
Hysteretic squashed entanglement in many-body quantum systems
Siddhartha Das, Alexander Yosifov, Jinzhao Sun
Entanglement in many-body quantum systems is distributed across spatial regions, where its structure often dictates the information-processing capabilities of the state. Yet, chara…
Extensible universal photonic quantum computing with nonlinearity
Shang Yu, Jinzhao Sun, Kuan-Cheng Chen +17
Universal quantum computing requires an architecture that supports both linear circuits and, crucially, strong nonlinear resources. For quantum photonic systems, integrating such n…
