Preparing Greenberger–Horne–Zeilinger Entangled Photon Fock States of Three Cavities Coupled by a Superconducting Flux Qutrit

“…In addition, superconducting qubits and microwave resonators can be fabricated with modern technology. Furthermore, the strong coupling limit between the superconducting qubits and the cavity field was predicated earlier [29,30] and has been experimentally demonstrated [31,32].So far, many theoretical proposals have been presented for the preparation of Fock states, coherent states, squeezed states, the Schördinger Cat state, and an arbitrary superposition of Fock states of a single superconducting cavity [33][34][35][36]. Recently, there is much interest in generation of entangled states of qubits or photons in multiple cavities because of their importance in realizing large-scale QIP within cavity QED.…”

“…Superconducting qubits, such as flux, charge and phase qubits, have long decoherence time [17,18] and experiments have realized quantum operations in single and multiple superconducting qubits with states read out [19][20][21][22][23]. A cavity (such as coplanar waveguide, microstrip resonator and lumped-circuit resonator and so on) can act as a quantum bus, which can mediate long-distance and fast interaction between distant superconducting qubits [24][25][26][27][28][29]. In addition, superconducting qubits and microwave resonators can be fabricated with modern technology.…”

Deterministic transfer of an unknown qutrit state assisted by the low- Q microwave resonators

“…On the other hand, quantum state transfer is an essential primitive in QIP and quantum communication. Over the past years, a great many of theoretical proposals have been proposed for realizing SC qubit-to-qubit quantum state transfer based on cavity/circuit QED [34][35][36][37][38][39][40][41][42][43]. Moreover, the quantum state transfer between the SC qubits has been experimentally demonstrated in circuit QED.…”

“…The transmission of an unknown quantum state between two solid-state qutrits is still an open problem in QIP. Hitherto, the previous works are mainly focused on the quantum state transfer from one qubit to another qubit [34][35][36][37][38][39][40][41][42][43][44][45][46][47]. Few proposals are related to quantum state transfer between qutrits and there is no experimental study is reported for the qutrit-to-qutrit quantum state transfer in circuit QED.…”
