Nearly tight Trotterization of interacting electrons
Yuan Su, Hsin-Yuan Huang, Earl T. Campbell
We consider simulating quantum systems on digital quantum computers. We show that the performance of quantum simulation can be improved by simultaneously exploiting commutativity o…
Faster Digital Quantum Simulation by Symmetry Protection
Minh C. Tran, Yuan Su, Daniel Carney +1
Simulating the dynamics of quantum systems is an important application of quantum computers and has seen a variety of implementations on current hardware. We show that by introduci…
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…
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…
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…
