Coherent photons and macroscopic cat states generated by a cyclic artificial atom with broken symmetry
C. P. Sun, Yu-xi Liu, L. F. Wei +1
We propose a novel method to generate non-classical states of a single-mode microwave field, and to produce macroscopic cat states by virtue of a three-level system with -shaped…
On the relative quantum entanglement with respect to tensor product structure
X. F. Liu, C. P. Sun
Mathematical foundation of the novel concept of quantum tensor product by Zanardi et al is rigorously established. The concept of relative quantum entanglement is naturally introdu…
Spin wave based quantum storage of electronic spin with a ring array of nuclear spins
Y. D. Wang, Y. Li, Z. Song +1
We propose a solid state based protocol to implement the universal quantum storage for electronic spin qubit. The quantum memory in this scheme is the spin wave excitation in the r…
Holonomic Quantum Computation Using Rf-SQUIDs Coupled Through A Microwave Cavity
P. Zhang, Z. D. Wang, J. D. Sun +1
We propose a new scheme to realize holonomic quantum computation with rf-SQUID qubits in a microwave cavity. In this scheme associated with the non-Abelian holonomies, the single-q…
Quantum decoherence in a supersymmetric mechanical system
T. Shi, Z. Song, C. P. Sun
We make a novel observation about the decoherence phenomenon of the fermion in the Witten's supersymmetric (SUSY) quantum mechanical model. It is shown that, when the bosonic partn…
Creating Steady Atom-Molecule Entanglement by Demkov-Kunike Type Non-adiabatic Transition
P. Zhang, H. T. Quan, C. P. Sun
We, based on the photoassociation of fermion atoms into bosonic molecules, propose a scheme to create the steady entanglement between the atom state and the molecule state inside a…
