Quantum thermal transistor based on the qubit-qutrit coupling
Bao-qing Guo, Tong Liu, Chang-shui Yu
A quantum thermal transistor is designed by the strong coupling between one qubit and one qutrit which are in contact with three heat baths with different temperatures. The thermal…
Multifunctional quantum thermal device utilizing three qubits
Bao-qing Guo, Tong Liu, Chang-shui Yu
Quantum thermal devices which can manage heat as their electronic analogues for the electronic currents have attracted increasing attention. Here a three-terminal quantum thermal d…
Creation of superposition of arbitrary states encoded in two three-dimensional cavities
Tong Liu, Yang Zhang, Bao-qing Guo +2
The principle of superposition is a key ingredient for quantum mechanics. A recent work [M. Oszmaniec et al., Phys. Rev. Lett. 116, 110403 (2016)] has shown that a quantum adder th…
One-step implementation of a hybrid Fredkin gate with quantum memories and single superconducting qubit in circuit QED and its applications
Tong Liu, Bao-Qing Guo, Chang-Shui Yu +1
In a recent remarkable experiment [R. B. Patel et al., Science advances 2, e1501531 (2016)], a 3-qubit quantum Fredkin (i.e., controlled-SWAP) gate was demonstrated by using linear…
Circuit QED: Cross-Kerr-effect induced by a superconducting qutrit without classical pulses
Tong Liu, Chui-ping Yang, Yang Zhang +2
The realization of cross-Kerr nonlinearity is an important task for many applications in quantum information processing. In this work, we propose a method for realizing cross-Kerr…
Total quantum coherence and its applications
Chang-shui Yu, Yi-ren Yang, Bao-qing Guo
Quantum coherence is the most fundamental feature of quantum mechanics. The usual understanding of it depends on the choice of the basis, that is, the coherence of the same quantum…
Measurable genuine tripartite entanglement of ()-dimensional quantum states via only two simultaneous copies
Chang-shui Yu, Bao-qing Guo, Si-ren Yang
Usually, the three-tangle of a tripartite pure state of qubits can be directly measured with the simultaneous preparation of a not-less-than-four-fold copy of the state. We show th…
