Qualitative quantum simulation of resonant tunneling and localization with the shallow quantum circuits

Journal of Physics Communications
In a circuit-based quantum computer, the computing is performed via the discrete-time evolution driven by quantum gates. Accurate simulation of continuous-time evolution requires a large number of quantum gates and therefore suffers from more noise.

Reshaping quantum device noise via repetition code circuits

Physical Review Research
Noise of a quantum processor can be an important resource for simulating open quantum dynamics. However, this requires characterizing the device noise and then transforming it into a target structure.

Implementations of more general solid-state (SWAP) and controlled-(swap) gates

New Journal of Physics, 2019
Universal quantum gates are the core elements in quantum information processing. We design two schemes to realize more general (SWAP) ^1/ ^m and controlled-(swap) ^1/ ^m gates (for integer $m\geqslant 1$ ) by directing flying single photons to solid ...
