Fun with Graph States: Nonlocal Bell Pairs and the Arf Invariant
Bartlomiej Czech, Yichen Feng, Xianlai Wu +1
We study inner products and partial amplitudes of graph states--a commonly employed class of quantum states, which are specified by graphs. We find that the magnitudes of these qua…

Holographic entropy inequalities pass the majorization test
Bartlomiej Czech, Yichen Feng, Xianlai Wu +1
Quantities computed by minimal cuts, such as entanglement entropies achievable by the Ryu-Takayanagi proposal in the AdS/CFT correspondence, are constrained by linear inequalities.…

Identifying the -qubit state with quantum uncertainty relation
Zhi-Jie Liu, Hao-Nan Qiang, Jie Zhou +2
The state, a canonical representative of multipartite quantum entanglement, plays a crucial role in quantum information science due to its robust entanglement properties. Quant…
