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