Redefining the Quantum Supremacy Baseline With a New Generation Sunway Supercomputer
Xin Liu, Chu Guo, Yong Liu +11
A major milestone in the era of noisy intermediate scale quantum computers is \textit{quantum supremacy} [Nature \textbf{574}, 505 (2019)] claimed on the Sycamore quantum processor…
Closing the "Quantum Supremacy" Gap: Achieving Real-Time Simulation of a Random Quantum Circuit Using a New Sunway Supercomputer
Yong, Liu, Xin +13
We develop a high-performance tensor-based simulator for random quantum circuits(RQCs) on the new Sunway supercomputer. Our major innovations include: (1) a near-optimal slicing sc…
Typicality of nonequilibrium (quasi-)steady currents
Xiansong Xu, Chu Guo, Dario Poletti
The understanding of the emergence of equilibrium statistical mechanics has progressed significantly thanks to developments from typicality, canonical and dynamical, and from the e…
Transport and spectral properties of the XXXXZ diode and stability to dephasing
Kang Hao Lee, Vinitha Balachandran, Chu Guo +1
We study the transport and spectral property of a segmented diode formed by an XX XXZ spin chain. This system has been shown to become an ideal rectifier for spin current for l…
Variational quantum process tomography
Shichuan Xue, Yong Liu, Yang Wang +3
Quantum process tomography is an experimental technique to fully characterize an unknown quantum process. Standard quantum process tomography suffers from exponentially scaling of…
Population transfer under local dephasing
Wei Huang, Wentao Zhang, Chu Guo
Stimulated Raman adiabatic passage is a well-known technique for quantum population transfer due to its robustness again various sources of noises. Here we consider quantum populat…
Fast Laser Cooling Using Optimal Quantum Control
Xie-Qian Li, Shuo Zhang, Jie Zhang +3
Cooling down a trapped ion into its motional ground state is a central step for trapped ions based quantum information processing. State of the art cooling schemes often work under…
Steady state phonon occupation of EIT cooling: higher order calculations
Shuo Zhang, Tian-Ci Tian, Zheng-Yang Wu +5
Electromagnetically induced transparency (EIT) cooling has established itself as one of the most widely used cooling schemes for trapped ions during the past twenty years. Compared…
