A Criterion to identify maximally entangled nine-qubit state
Xinwei Zha, Irfan Ahmed, Da Zhang +1
We present a generalized criterion for maximally entangled nine-qubit states, whose minimum averaged subsystem purity should be equal to 1/14. In this note, we prove that absolutel…
Greatly enhanced intensity-difference squeezing for narrow-band quantum metrology applications
Da Zhang, Changbiao Li, Zhaoyang Zhang +4
Narrow-band intensity-difference squeezing beams have important applications in quantum metrology and gravitational wave detection. The best way to generate narrow-band intensity-d…
Unveiling the link between fractional Schrödinger equation and light propagation in honeycomb lattice
Da Zhang, Yiqi Zhang, Zhaoyang Zhang +5
We establish a link between the fractional Schrödinger equation (FSE) and light propagation in the honeycomb lattice (HCL) - the Dirac-Weyl equation (DWE). The fractional Laplacian…
Transport properties in the photonic super-honeycomb lattice - a hybrid fermionic and bosonic system
Hua Zhong, Yiqi Zhang, Yi Zhu +6
We report on transport properties of the super-honeycomb lattice, the band structure of which possesses a flat band and Dirac cones, according to the tight-binding approximation. T…
