The Heisenberg limit for laser coherence

no code implementations11 Sep 2020 Travis J. Baker, Seyed N. Saadatmand, Dominic W. Berry, Howard M. Wiseman

For an ideal laser beam [1, 2, 3], it can be thought of roughly as the number of photons emitted consecutively into the beam with the same phase.

Simulating Hamiltonian dynamics with a truncated Taylor series

no code implementations15 Dec 2014 Dominic W. Berry, Andrew M. Childs, Richard Cleve, Robin Kothari, Rolando D. Somma

We describe a simple, efficient method for simulating Hamiltonian dynamics on a quantum computer by approximating the truncated Taylor series of the evolution operator.
