Competitions between quantum correlations in the quantum-memory-assisted entropic uncertainty relation
Ming-Liang Hu, Heng Fan
With the aid of a quantum memory, the uncertainty about the measurement outcomes of two incompatible observables of a quantum system can be reduced. We investigate this measurement…
Notes on teleportation in an expanding space
Jun Feng, Wen-Li Yang, Yao-Zhong Zhang +1
We investigate the quantum teleportation between a conformal detector Alice and an inertial detector Bob in de Sitter space in two schemes, (i) one uses free scalar modes and (ii)…
State-independent experimental test of quantum contextuality in solid state system
Xin-Yu Pan, Yan-Chun Chang, Gang-Qin Liu +1
Quantum mechanics implies that not all physical properties can be simultaneously well defined, such as the momentum and position due to Heisenberg uncertainty principle. Some alter…
1/2+1/2>1 for quantum error correction
Zhuo Wang, Sixia Yu, Heng Fan +1
Quantum error correction assisted by entanglement helps to transmit the encoded qudits through quantum channels with some of them being noiseless. Here we consider a more realistic…
Minimal sets determining universal and phase-covariant quantum cloning
Li Jing, Yi-Nan Wang, Han-Duo Shi +2
We study the minimal input sets which can determine completely the universal and the phase-covariant quantum cloning machines. We find that the universal quantum cloning machine, w…
