Quantum Simulation of Coupled Harmonic Oscillators: From Theory to Implementation
Viraj Dsouza, Weronika Golletz, Dimitrios Kranas +3
We investigate the quantum algorithm of Babbush et al. (arXiv:2303.13012v3) for simulating coupled harmonic oscillators, which promises exponential speedups over classical methods.…

Recoherence, adiabaticity, and Markovianity in Gaussian maps
Dimitrios Kranas, Julien Grain, Vincent Vennin
Motivated by the recent discovery of situations where cosmological fluctuations recohere during inflation, we investigate the relationship between quantum recoherence (late-time pu…
