Free Mode Removal and Mode Decoupling for Simulating General Superconducting Quantum Circuits
Dawei Ding, Hsiang-Sheng Ku, Yaoyun Shi +1
Superconducting quantum circuits is one of the leading candidates for a universal quantum computer. Designing novel qubit and multiqubit superconducting circuits requires the abili…
Finding Angles for Quantum Signal Processing with Machine Precision
Rui Chao, Dawei Ding, Andras Gilyen +2
We describe an algorithm for finding angle sequences in quantum signal processing, with a novel component we call halving based on a new algebraic uniqueness theorem, and another w…
Alibaba Cloud Quantum Development Platform: Surface Code Simulations with Crosstalk
Cupjin Huang, Xiaotong Ni, Fang Zhang +11
We report, in a sequence of notes, our work on the Alibaba Cloud Quantum Development Platform (AC-QDP). AC-QDP provides a set of tools for aiding the development of both quantum co…
Kitaev's quantum double model as an error correcting code
Shawn X. Cui, Dawei Ding, Xizhi Han +4
Kitaev's quantum double models in 2D provide some of the most commonly studied examples of topological quantum order. In particular, the ground space is thought to yield a quantum…
Entropy Bound for the Classical Capacity of a Quantum Channel Assisted by Classical Feedback
Dawei Ding, Yihui Quek, Peter W. Shor +1
We prove that the classical capacity of an arbitrary quantum channel assisted by a free classical feedback channel is bounded from above by the maximum average output entropy of th…
A Quantum Multiparty Packing Lemma and the Relay Channel
Dawei Ding, Hrant Gharibyan, Patrick Hayden +1
Optimally encoding classical information in a quantum system is one of the oldest and most fundamental challenges of quantum information theory. Holevo's bound places a hard upper…
