Testing the unified bounds of quantum speed limit
Yaozu Wu, Jiale Yuan, Chuanyu Zhang +12
Quantum speed limits (QSLs) impose fundamental constraints on the evolution speed of quantum systems. Traditionally, the Mandelstam-Tamm (MT) and Margolus-Levitin (ML) bounds have…
Robust multi-party semi-quantum private comparison protocols with decoherence-free states against collective noises
Lihua Gong, Zhenyong Chen, Liguo Qin +1
Based on decoherence-free states, two multi-party semi-quantum private comparison protocols are proposed to counteract collective noises. One could resist the collective-dephasing…
Nonclassical properties of Hermite polynomial's excitation on squeezed vacuum and its decoherence in phase-sensitive reservoirs
Shi-You Liu, Ya-Zhou Li, Li-Yun Hu +3
We introduce Hermite polynomial excitation squeezed vacuum (SV) H_{n}(O)S(r)|0> with O=u a+v a^{+}. We investigate analytically the nonclassical properties according to Mandel's Q…
Improving entanglement of even entangled coherent states by a coherent superposition of photon subtraction and addition
Shi-You Liu, Jie-Hui Huang, Li-Yun Hu +3
A new entangled quantum state is introduced by applying local coherent superposition (ra^+ +ta) of photon subtraction and addition to each mode of even entangled coherent state (EE…
