Amplification and generation bounds of gravity-induced entanglement in pulsed optomechanical systems
Daisuke Miki, Alfred Li, Yanbei Chen
We investigate gravity-induced entanglement between the output optical fields of two red-detuned pulsed optomechanical systems with their masses coupled by mutual gravitational int…
Universal Bound for Entanglement Generation
Alfred Li, Daisuke Miki, Yanbei Chen
We derive a universal condition for entanglement generation under general bilinear interactions in the presence of white thermal noise. While various protocols have been proposed t…
Towards sample-optimal learning of bosonic Gaussian quantum states
Senrui Chen, Francesco Anna Mele, Marco Fanizza +5
Continuous-variable systems enable key quantum technologies in computation, communication, and sensing. Bosonic Gaussian states emerge naturally in various such applications, inclu…
Fokker-Planck equation governing the distribution of walkers in AFQMC
Alfred Li, Ankit Mahajan, Sandeep Sharma
Auxiliary-field quantum Monte Carlo (AFQMC) is typically formulated as an open-ended random walk in an overcomplete space of Slater determinants, implemented through a Langevin equ…
Decoherence-Free Subspaces Cannot Prevent the Collapse of Wave Functions
Alfred Li, Herschel A. Rabitz, Benjamin Lienhard
Efficacious quantum information processing relies on extended coherence and precise control. Investigating the limitations surrounding quantum processors is vital for their advance…
