Rajveer Nehra, Ryotatsu Yanagimoto, Hideo Mabuchi, Alireza Marandi · 2023
We present a method for generating squeezed Schr¨odinger cat states and cubic phase states via quantum nondemolition measurement of the squared-quadrature operator, offering a realistic route to fault-tolerant universal continuous-variable quantum computation.
