Revealing Entanglement-Growth Mechanisms through the Magic Barrier
Lv Zhang, Shi-Xin Zhang, Heng Fan +1
Quantum entanglement and magic are complementary resources underlying quantum computational advantage, yet their dynamical relation in many-body systems remains poorly understood.…
Absence of poor local minima in matrix product states
Hao-Kai Zhang, Chenghong Zhu, Shuo Liu +2
Quantum circuits suffer from severe trainability issues: even shallow circuits are swamped with poor local minima. Yet matrix product states (MPS), which can be prepared by sequent…
Noisy Monitored Quantum Circuits
Shuo Liu, Shao-Kai Jian, Shi-Xin Zhang
Noisy monitored quantum circuits have emerged as a versatile and unifying framework connecting quantum many-body physics, quantum information, and quantum computation. In this revi…
Nonstabilizerness Mpemba Effects
Zhenyu Xiao, Hao-Kai Zhang, Shuo Liu
Quantum state preparation can be strikingly counterintuitive: the fastest route to a target state need not start from the apparently closest initial condition. We uncover such a qu…
TensorCircuit-NG: A Universal, Composable, and Scalable Platform for Quantum Computing and Quantum Simulation
Shi-Xin Zhang, Yu-Qin Chen, Weitang Li +22
We present TensorCircuit-NG, a next-generation quantum software platform designed to bridge the gap between quantum physics, artificial intelligence, and high-performance computing…
Tunable discrete quasi-time crystal from a single drive
Xu Feng, Shuo Liu, Shu Chen +1
The search for exotic temporal orders in quantum matter, such as discrete quasi-time crystals (DQTCs), has become an important theme in nonequilibrium physics. However, realizing t…
