Implementation of multiparticle quantum speed limits on observables
Rui-Heng Miao, Zhao-Di Liu, Chen-Xi Ning +4
The energy-time uncertainty relation limits the maximum speed of quantum system evolution and is crucial for determining whether quantum tasks can be accelerated. However, multipar…

Quantum sequel of neural network training
Hao Zhang, Alex Kamenev
Training of neural networks (NNs) has emerged as a major consumer of both computational and energy resources. Quantum computers were coined as a root to facilitate training, but no…

Computational complexity of three-dimensional Ising spin glass: Lessons from D-Wave annealer
Hao Zhang, Alex Kamenev
Finding an exact ground state of a three-dimensional (3D) Ising spin glass is proven to be an NP-hard problem (i.e., at least as hard as any problem in the nondeterministic polynom…
