Quantum discord induced by white noises
Jia-sen Jin, Chang-shui Yu, Pei Pei +1
We discuss the creation of quantum discord between two two-level atoms trapped in an optical cavity in a noisy environment. It is shown that nonzero steady-state quantum discord be…
Nondestructive identification of the Bell diagonal state
Jia-sen Jin, Chang-shui Yu, He-shan Song
We propose a scheme for identifying an unknown Bell diagonal state. In our scheme the measurements are performed on the probe qubits instead of the Bell diagonal state. The disting…
Quantum nondemolition measurement of the Werner state
Jia-sen Jin, Chang-shui Yu, Pei Pei +1
We propose a theoretical scheme of quantum nondemolition measurement of two-qubit Werner state. We discuss our scheme with the two qubits restricted in a local place and then exten…
Direct scheme for measuring the geometric quantum discord
Jia-sen Jin, Feng-yang Zhang, Chang-shui Yu +1
We propose a scheme to directly measure the exact value of geometric quantum discord of an arbitrary two-qubit state. We only need to perform the projective measurement in the all…
