Generating collective spin cat states via photon-number measurements near the Dicke critical point
Taiga Nakamoto, Shohei Imai, Kazuaki Takasan
We propose a method for generating collective spin cat states in a cavity-coupled atomic ensemble by exploiting strong light-matter entanglement and anti-squeezing associated with…
Heralded ultrafast generation of macroscopic quantum states in matter with bright squeezed vacuum light
Shohei Imai
We show that bright squeezed vacuum light, combined with a single-shot quadrature measurement of the post-interaction light, enables the ultrafast generation of macroscopic quantum…
Macroscopic Schrödinger-cat states of nonequilibrium electrons induced by cat-state optical driving and projective measurements on the light field
Shohei Imai
We show that projective measurements on quantum light can induce macroscopic cat states in many-electron systems driven by such light. Here we investigate the quantum dynamics of $…
Electron dynamics induced by quantum cat-state light
Shohei Imai, Atsushi Ono, Naoto Tsuji
We present an effective theory for describing electron dynamics driven by an optical external field in a Schrödinger's cat state. We show that the reduced electron density matrix e…
