Non-Hermitian Bloch Oscillations
Yanyan He, Tomoki Ozawa
We establish a general framework for non-Hermitian Bloch oscillations by investigating the wave-packet dynamics in one-dimensional non-Hermitian lattices driven by a dc force. The…

Quantum walk with coherent multiple translations induces fast quantum gate operations
Yixiang Zhang, Xin Qiao, Luojia Wang +4
Quantum walks with one-dimensional translational symmetry are important for quantum algorithms, where the speed-up of the diffusion speed can be reached if long-range couplings are…
