چکیده

Quantum state transfer (QST) and entangled generation (ESG) are important building blocks for modern quantum information processing. To achieve these tasks, convention wisdom is to consult the adiabatic evolution, which time-consuming, thus of low fidelity. Here, using shortcut adiabaticity technique, we propose a general method realize high-fidelity fast QST ESG in cavity-coupled many qubits system via its dark pathways, can be further designed tasks with different optimization purpose. Specifically, proper pathway, between any two achieved without decoupling others, simplifies experimental demonstrations. Meanwhile, among all also realized single step. In addition, our scheme implemented systems, illustrate implementation on superconducting circuits. Therefore, powerful strategy selective manipulation, promising cavity coupled systems could find convenient applications

Faithful conditional quantum state transfer between weakly coupled qubits

One of the strengths of quantum information theory is that it can treat quantum states without referring to their particular physical representation. In principle, quantum states can be therefore fully swapped between various quantum systems by their mutual interaction and this quantum state transfer is crucial for many quantum communication and information processing tasks. In practice, howeve...

Fast adiabatic quantum state transfer and entanglement generation between two atoms via dressed states

We propose a dressed-state scheme to achieve shortcuts to adiabaticity in atom-cavity quantum electrodynamics for speeding up adiabatic two-atom quantum state transfer and maximum entanglement generation. Compared with stimulated Raman adiabatic passage, the dressed-state scheme greatly shortens the operation time in a non-adiabatic way. By means of some numerical simulations, we determine the ...

Institutional Repository Quantum entanglement of ux qubits via a resonator

We show that flux qubits can be efficiently entangled by inductive coupling to a tunable resonant circuit, in the scheme reminiscent of atoms’ entanglement through the optical cavity mode. It is shown, in particular, that the singlephoton excitation of the resonator produces the pure Bell state of qubits with the completely disentangled LC circuit. 03.67.Lx; 85.25.Cp; 03.65.Ud Typeset using REVTEX

Steady-state entanglement of spatially separated qubits via quantum bath engineering

We propose a scheme for driving a dimer of spatially separated qubits into a maximally entangled nonequilibrium steady state. A photon-mediated retarded interaction between the qubits is realized by coupling them to two tunnel-coupled leaky cavities where each cavity is driven by a coherent microwave tone. The proposed cooling mechanism relies on striking the right balance between the unitary a...

Voltage-Controlled Entanglement between Quantum- Dot Molecule and its Spontaneous Emission Fields via Quantum Entropy

The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...
