Quantifying Spontaneously Symmetry Breaking of Quantum Many-body Systems
G. H. Dong, Y. N. Fang, C. P. Sun
Spontaneous symmetry breaking is related to the appearance of emergent phenomena, while a non-vanishing order parameter has been viewed as the sign of turning into such symmetry br…
Quantification of Symmetry
Y. N. Fang, G. H. Dong, D. L. Zhou +1
Symmetry is conventionally described in a contrariety manner that the system is either completely symmetric or completely asymmetric. Using group theoretical approach to overcome t…
Encoding a logical qubit into physical qubits
B. Zeng, D. L. Zhou, Z. Xu +2
We propose two protocols to encode a logical qubit into physical qubits relying on common types of qubit-qubit interactions in as simple forms as possible. We comment on its experi…
Quantum computation based on d-level cluster states
D. L. Zhou, B. Zeng, Z. Xu +1
The concept of qudit (a d-level system) cluster state is proposed by generalizing the qubit cluster state (Phys. Rev. Lett. \textbf{86}, 910 (2001)) according to the finite dimensi…
Idealization Second Quantization of Composite Particles
D. L. Zhou, S. Y. Yu, C. P. Sun
A practical method is developed to deal with the second quantization of the many-body system containing the composite particles. In our treatment, the modes associated with composi…
Decoherence in a single trapped ion due to engineered reservoir
X. X. Yi, D. L. Zhou, C. P. Sun
The decoherence in trapped ion induced by coupling the ion to the engineered reservoir is studied in this paper. The engineered reservoir is simulated by random variations in the t…
