Local Hamiltonian Problem with succinct ground state is MA-Complete
Jiaqing Jiang
Finding the ground energy of a quantum system is a fundamental problem in condensed matter physics and quantum chemistry. Existing classical algorithms for tackling this problem of…
Lower bound for the T count via unitary stabilizer nullity
Jiaqing Jiang, Xin Wang
We introduce magic measures to quantify the nonstabilizerness of multiqubit quantum gates and establish lower bounds on the count for fault-tolerant quantum computation. First,…
Physical Implementability of Linear Maps and Its Application in Error Mitigation
Jiaqing Jiang, Kun Wang, Xin Wang
Completely positive and trace-preserving maps characterize physically implementable quantum operations. On the other hand, general linear maps, such as positive but not completely…
General Quantum Bernoulli Factory: Framework Analysis and Experiments
Yong Liu, Jiaqing Jiang, Pingyu Zhu +13
The unremitting pursuit for quantum advantages gives rise to the discovery of a quantum-enhanced randomness processing named quantum Bernoulli factory (QBF). This quantum enhanced…
Optimal Space-Depth Trade-Off of CNOT Circuits in Quantum Logic Synthesis
Jiaqing Jiang, Xiaoming Sun, Shang-Hua Teng +3
Decoherence -- in the current physical implementations of quantum computers -- makes depth reduction a vital task in quantum-circuit design. Moore and Nilsson (SIAM Journal of Comp…
Quantum-to-Quantum Bernoulli Factory
Jiaqing Jiang, Jialin Zhang, Xiaoming Sun
Given a coin with unknown bias , can we exactly simulate another coin with bias ? The exact set of simulable functions has been well characterized 20 years ago. I…
Local unitary classification for sets of generalized Bell states
Bujiao Wu, Jiaqing Jiang, Jialin Zhang +2
In this paper, we study the local unitary classification for pairs (triples) of generalized Bell states, based on the local unitary equivalence of two sets. In detail, we firstly i…
