Hamiltonian simulation with nearly optimal dependence on spectral norm
Guang Hao Low
We present a quantum algorithm for approximating the real time evolution of an arbitrary -sparse Hamiltonian to error , given black-box access to the positions and…
Black-box quantum state preparation without arithmetic
Yuval R. Sanders, Guang Hao Low, Artur Scherer +1
Black-box quantum state preparation is an important subroutine in many quantum algorithms. The standard approach requires the quantum computer to do arithmetic, which is a key cont…
Quantum singular value transformation and beyond: exponential improvements for quantum matrix arithmetics
András Gilyén, Yuan Su, Guang Hao Low +1
Quantum computing is powerful because unitary operators describing the time-evolution of a quantum system have exponential size in terms of the number of qubits present in the syst…
Hamiltonian Simulation in the Interaction Picture
Guang Hao Low, Nathan Wiebe
We present a low-space overhead simulation algorithm based on the truncated Dyson series for time-dependent quantum dynamics. This algorithm is applied to simulating time-independe…
