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…
