Transferring quantum entangled states between multiple single-photon-state qubits and coherent-state qubits in circuit QED
Qi-Ping Su, Hanyu Zhang, Chui-Ping Yang
We present a way to transfer maximally- or partially-entangled states of n single-photon-state (SPS) qubits onto n coherent-state (CS) qubits, by employing 2n microwave cavities co…
Generation of quantum entangled states of multiple groups of qubits distributed in multiple cavities
Tong Liu, Qi-Ping Su, Yu Zhang +2
Provided that cavities are initially in a Greenberger-Horne-Zeilinger (GHZ) entangled state, we show that GHZ states of N-group qubits distributed in N cavities can be created via…
A framework for quantum homomorphic encryption with experimental demonstration
Yu Zhang, Li Yu, Qi-Ping Su +7
Quantum homomorphic encryption (QHE) is an encryption method that allows quantum computation to be performed on one party's private data with the program provided by another party,…
An efficient protocol of quantum walk in circuit QED
Jia-Qi Zhou, Qi-Ping Su, Chui-Ping Yang
Implementation of discrete-time quantum walk (DTQW) with superconducting qubits is difficult since on-chip superconducting qubits cannot hop between lattice sites. We propose an ef…
Experimental demonstration of quantum walks with initial superposition states
Qi-Ping Su, Yu Zhang, Li Yu +9
The preparation of initial superposition states of discrete-time quantum walks (DTQWs) are necessary for the study and applications of DTQWs. In linear optics, it is easy to prepar…
Universal controlled-phase gate with cat-state qubits in circuit QED
Yu Zhang, Xiong Zhao, Li Yu +2
Cat-state qubits (qubits encoded with cat states) have recently drawn intensive attention due to their enhanced life times with quantum error correction. We here propose a method t…
