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…
Unitary Selective Coupled-Cluster Method
Dmitry A. Fedorov, Yuri Alexeev, Stephen K. Gray +1
Simulating molecules using the Variational Quantum Eigensolver method is one of the promising applications for NISQ-era quantum computers. Designing an efficient ansatz to represen…
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…
Giant Optomechanical Coupling in the Charge Density Wave State of Tantalum Disulfide
Anubhab Haldar, Cristian L. Cortes, Stephen K. Gray +2
We study the coupling of light and the structural order parameter in the charge density wave (CDW) state of the layered transition-metal dichalcogenide, Tantalum Disulfide ($1T-\ma…
