Optimal Perfect Distinguishability between Unitaries and Quantum Operations
Cheng Lu, Jianxin Chen, Runyao Duan
We study optimal perfect distinguishability between a unitary and a general quantum operation. In 2-dimensional case we provide a simple sufficient and necessary condition for sequ…
Principle of Maximum Entropy and Ground Spaces of Local Hamiltonians
Jianxin Chen, Zhengfeng Ji, Mary Beth Ruskai +2
The structure of the ground spaces of quantum systems consisting of local interactions is of fundamental importance to different areas of physics. In this Letter, we present a nece…
No-go Theorem for One-way Quantum Computing on Naturally Occurring Two-level Systems
Jianxin Chen, Xie Chen, Runyao Duan +2
One-way quantum computing achieves the full power of quantum computation by performing single particle measurements on some many-body entangled state, known as the resource state.…
