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…
Topological phase transition in the quasiperiodic disordered Su-Schriffer-Heeger chain
Tong Liu, Hao Guo
We study the stability of the topological phase in one-dimensional Su-Schrieffer-Heeger chain subject to the quasiperiodic hopping disorder. We investigate two different hopping di…
Novel mobility edges in the off-diagonal disordered tight-binding models
Tong Liu, Hao Guo
We study the one-dimensional tight-binding models which include a slowly varying, incommensurate off-diagonal modulation on the hopping amplitude. Interestingly, we find that the m…
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…
Deterministic transfer of an unknown qutrit state assisted by the low-Q microwave resonators
Tong Liu, Yang Zhang, Chang-Shui Yu +1
Qutrits (i.e., three-level quantum systems) can be used to achieve many quantum information and communication tasks due to their large Hilbert spaces. In this work, we propose a sc…
