Pure dephasing induced single-photon parametric down-conversion in an ultrastrong coupled plasmon-exciton system
Ruben Pompe, Matthias Hensen, Matthew Otten +2
In coupled quantum systems pure dephasing mechanisms acting on one constituent of the hybrid system break symmetry and enable optical transitions which are forbidden in the non-cou…
Localized Quantum Chemistry on Quantum Computers
Matthew Otten, Matthew R. Hermes, Riddhish Pandharkar +3
Quantum chemistry calculations of large, strongly correlated systems are typically limited by the computation cost that scales exponentially with the size of the system. Quantum al…
Quantum Krylov subspace algorithms for ground and excited state energy estimation
Cristian L. Cortes, Stephen K. Gray
Quantum Krylov subspace diagonalization (QKSD) algorithms provide a low-cost alternative to the conventional quantum phase estimation algorithm for estimating the ground and excite…
Sample-efficient adaptive calibration of quantum networks using Bayesian optimization
Cristian L. Cortes, Pascal Lefebvre, Nikolai Lauk +4
Indistinguishable photons are imperative for advanced quantum communication networks. Indistinguishability is difficult to obtain because of environment-induced photon transformati…
Ground-state cooling enabled by critical coupling and dark entangled states
Cristian L. Cortes, Matthew Otten, Stephen K. Gray
We analyze the cooling of a mechanical resonator coupled to an ensemble of interacting two-level systems via an open quantum systems approach. Using an exact analytical result, we…
Coherent photon coincidence spectroscopy of single quantum systems
Matthew Otten, Tristan Kenneweg, Matthias Hensen +2
Non-equilibrium photon correlations of coherently excited single quantum systems can reveal their internal quantum dynamics and provide spectroscopic access. Here we propose and di…
