Destructive Error Interference in Product-Formula Lattice Simulation
Minh C. Tran, Su-Kuan Chu, Yuan Su +2
Quantum computers can efficiently simulate the dynamics of quantum systems. In this paper, we study the cost of digitally simulating the dynamics of several physically relevant sys…
Quantum oscillations and electronic structures in large Chern number semimetal RhSn
Sheng Xu, Liqin Zhou, Huan Wang +5
We report the magnetoresistance, Hall effect, de Haas-van Alphen (dHvA) oscillations and the electronic structures of single crystal RhSn, which is a typical material of CoSi famil…
A Theory of Trotter Error
Andrew M. Childs, Yuan Su, Minh C. Tran +2
The Lie-Trotter formula, together with its higher-order generalizations, provides a direct approach to decomposing the exponential of a sum of operators. Despite significant effort…
Interlayer quantum transport in Dirac semimetal BaGa
Sheng Xu, Changhua Bao, Yi-Yan Wang +8
Quantum limit is quite easy to achieve once the band crossing exists exactly at the Fermi level () in topological semimetals. In multilayered Dirac fermion system, the density…
Time-dependent Hamiltonian simulation with -norm scaling
Dominic W. Berry, Andrew M. Childs, Yuan Su +2
The difficulty of simulating quantum dynamics depends on the norm of the Hamiltonian. When the Hamiltonian varies with time, the simulation complexity should only depend on this qu…
Quantifying the magic of quantum channels
Xin Wang, Mark M. Wilde, Yuan Su
To achieve universal quantum computation via general fault-tolerant schemes, stabilizer operations must be supplemented with other non-stabilizer quantum resources. Motivated by th…
Nearly optimal lattice simulation by product formulas
Andrew M. Childs, Yuan Su
We consider simulating an -qubit Hamiltonian with nearest-neighbor interactions evolving for time on a quantum computer. We show that this simulation has gate complexity $(n…
