Product Formulas for Exponentials of Commutators
Andrew M. Childs, Nathan Wiebe
We provide a recursive method for constructing product formula approximations to exponentials of commutators, giving the first approximations that are accurate to arbitrarily high…
Efficient simulation scheme for a class of quantum optics experiments with non-negative Wigner representation
Victor Veitch, Nathan Wiebe, Christopher Ferrie +1
We provide a scheme for efficient simulation of a broad class of quantum optics experiments. Our efficient simulation extends the continuous variable Gottesman-Knill theorem to a l…
Information-theoretic equilibration: the appearance of irreversibility under complex quantum dynamics
Cozmin Ududec, Nathan Wiebe, Joseph Emerson
The question of how irreversibility can emerge as a generic phenomena when the underlying mechanical theory is reversible has been a long-standing fundamental problem for both clas…
Robust Online Hamiltonian Learning
Christopher E. Granade, Christopher Ferrie, Nathan Wiebe +1
In this work we combine two distinct machine learning methodologies, sequential Monte Carlo and Bayesian experimental design, and apply them to the problem of inferring the dynamic…
Quantum Data Fitting
Nathan Wiebe, Daniel Braun, Seth Lloyd
We provide a new quantum algorithm that efficiently determines the quality of a least-squares fit over an exponentially large data set by building upon an algorithm for solving sys…
Hamiltonian Simulation Using Linear Combinations of Unitary Operations
Andrew M. Childs, Nathan Wiebe
We present a new approach to simulating Hamiltonian dynamics based on implementing linear combinations of unitary operations rather than products of unitary operations. The resulti…
