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…
Mosaic spin models with topological order
S. Yang, D. L. Zhou, C. P. Sun
We study a class of two-dimensional spin models with the Kitaev-type couplings in mosaic structure lattices to implement topological orders. We show that they are exactly solvable…
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…
