Quantum simulation for time-dependent Hamiltonians -- with applications to non-autonomous ordinary and partial differential equations
Yu Cao, Shi Jin, Nana Liu
Non-autonomous dynamical systems appear in a very wide range of interesting applications, both in classical and quantum dynamics, where in the latter case it corresponds to having…
Randomness-enhanced expressivity of quantum neural networks
Yadong Wu, Juan Yao, Pengfei Zhang +1
As a hybrid of artificial intelligence and quantum computing, quantum neural networks (QNNs) have gained significant attention as a promising application on near-term, noisy interm…
Analog quantum simulation of partial differential equations
Shi Jin, Nana Liu
Quantum simulators were originally proposed for simulating one partial differential equation (PDE) in particular - Schrodinger's equation. Can quantum simulators also efficiently s…
Universal Quantum Optimization with Cold Atoms in an Optical Cavity
Meng Ye, Ye Tian, Jian Lin +6
Cold atoms in an optical cavity have been widely used for quantum simulations of many-body physics, where the quantum control capability has been advancing rapidly in recent years.…
Quantum simulation of discrete linear dynamical systems and simple iterative methods in linear algebra via Schrodingerisation
Shi Jin, Nana Liu
Quantum simulation is known to be capable of simulating certain dynamical systems in continuous time -- Schrodinger's equations being the most direct and well-known -- more efficie…
The Sub-Exponential Critical Slowing Down at Floquet Time Crystal Phase Transition
Wenqian Zhang, Yadong Wu, Xingze Qiu +2
Critical slowing down (CSD) has been a trademark of critical dynamics for equilibrium phase transitions of a many-body system, where the relaxation time for the system to reach the…
