A sparse-sampling approach for the fast computation of matrices: application to molecular vibrations
Jacob N. Sanders, Xavier Andrade, Alán Aspuru-Guzik
This article presents a new method to compute matrices from numerical simulations based on the ideas of sparse sampling and compressed sensing. The method is useful for problems wh…
Clock Quantum Monte Carlo: an imaginary-time method for real-time quantum dynamics
Jarrod R. McClean, Alán Aspuru-Guzik
In quantum information theory, there is an explicit mapping between general unitary dynamics and Hermitian ground state eigenvalue problems known as the Feynman-Kitaev Clock. A pro…
Chemical Basis of Trotter-Suzuki Errors in Quantum Chemistry Simulation
Ryan Babbush, Jarrod McClean, Dave Wecker +2
Although the simulation of quantum chemistry is one of the most anticipated applications of quantum computing, the scaling of known upper bounds on the complexity of these algorith…
Compact wavefunctions from compressed imaginary time evolution
Jarrod R. McClean, Alán Aspuru-Guzik
Simulation of quantum systems promises to deliver physical and chemical predictions for the frontiers of technology. Unfortunately, the exact representation of these systems is pla…
Quantum nonlinear optics with polar J-aggregates in microcavities
Felipe Herrera, Borja Peropadre, Leonardo A. Pachon +2
We show that an ensemble of organic dye molecules with permanent electric dipole moments embedded in a microcavity can lead to strong optical nonlinearities at the single photon le…
Linear-algebraic bath transformation for simulating complex open quantum systems
Joonsuk Huh, Sarah Mostame, Takatoshi Fujita +2
In studying open quantum systems, the environment is often approximated as a collection of non-interacting harmonic oscillators, a configuration also known as the star-bath model.…
