Hamiltonian Simulation by Qubitization
Guang Hao Low, Isaac L. Chuang
We present the problem of approximating the time-evolution operator to error , where the Hamiltonian $\hat{H}=(\langle G|\otimes\hat{\mathcal{I}})\hat{U}(|G\ran…
Fixed-Point Adiabatic Quantum Search
Alexander M. Dalzell, Theodore J. Yoder, Isaac L. Chuang
Fixed-point quantum search algorithms succeed at finding one of target items among total items even when the run time of the algorithm is longer than necessary. While the f…
Optimal Hamiltonian Simulation by Quantum Signal Processing
Guang Hao Low, Isaac L. Chuang
The physics of quantum mechanics is the inspiration for, and underlies, quantum computation. As such, one expects physical intuition to be highly influential in the understanding a…
Heisenberg scaling of imaging resolution by coherent enhancement
Robert McConnell, Guang Hao Low, Theodore J. Yoder +4
Classical imaging works by scattering photons from an object to be imaged, and achieves resolution scaling as , with the imaging time. By contrast, the laws of quan…
Iterative Precision Measurement of Branching Ratios Applied to 5P states in 88Sr+
Helena Zhang, Michael Gutierrez, Guang Hao Low +4
We report on a method for measuring the branching ratios of dipole transitions of trapped atomic ions by performing nested sequences of population inversions. This scheme is broadl…
The methodology of resonant equiangular composite quantum gates
Guang Hao Low, Theodore J. Yoder, Isaac L. Chuang
The creation of composite quantum gates that implement quantum response functions dependent on some parameter of interest is often more of an art than a science. T…
