Squeezed comb states
Namrata Shukla, Stefan Nimmrichter, Barry C. Sanders
Continuous-variable codes are an expedient solution for quantum information processing and quantum communication involving optical networks. Here we characterize the squeezed comb,…

Quantum tetrachotomous states: Superposition of four coherent states on a line in phase space
Namrata Shukla, Naeem Akhtar, Barry C. Sanders
The well studied quantum optical Schrödinger cat state is a superposition of two distinguishable states, with quantum coherence between these macroscopically distinguishable states…

State-independent preparation uncertainty relations
Hubert de Guise, Lorenzo Maccone, Barry C. Sanders +1
The standard state-dependent Heisenberg-Robertson uncertainly-relation lower bound fails to capture the quintessential incompatibility of observables as the bound can be zero for s…
