Directional THz generation in hot Rb vapor excited to a Rydberg state
Mark Lam, Sambit B. Pal, Thibault Vogt +2
We optically excite Rb atoms in a heated vapor cell to a low-lying Rydberg state 10D and observe directional terahertz (THz) beams at 3.3 THz and 7.8 THz. These THz…
Low-cost Fredkin gate with auxiliary space
Wen-Qiang Liu, Hai-Rui Wei, Leong-Chuan Kwek
Effective quantum information processing is tantamount in part to the minimization the quantum resources needed by quantum logic gates. Here, we propose an optimization of an n-con…
Efficient Fusion of Photonic W-states with Nonunitary Partial-swap Gates
Hai-Rui Wei, Wen-Qiang Liu, Leong-Chuan Kwek
We introduce a nonunitary partial-swap gate for fusing arbitrary small-sized photonic W-states into a large-scale entangled network of W-state efficiently without ancillary photons…
Nonlinear two-photon Rabi-Hubbard model: superradiance and photon/photon-pair Bose-Einstein condensate
Shifeng Cui, B. Grémaud, Wenan Guo +1
We study the ground state phase diagram of a nonlinear two-photon Rabi-Hubbard (RH) model in one dimension using quantum Monte Carlo (QMC) simulations and density matrix renormaliz…
A universal graph description for one-dimensional exchange models
Jean Decamp, Jiangbin Gong, Huanqian Loh +1
We demonstrate that a large class of one-dimensional quantum and classical exchange models can be described by the same type of graphs, namely Cayley graphs of the permutation grou…
Magnetoelastic interaction in the two-dimensional magnetic material MnPS studied by first principles calculations and Raman experiments
Diana Vaclavkova, Alex Delhomme, Clément Faugeras +7
We report experimental and theoretical studies on the magnetoelastic interactions in MnPS. Raman scattering response measured as a function of temperature shows a blue shift of…
