Textures as a phase-transition probe for quantum spin chains
Heitor P. Casagrande, Isaac M. Carvalho, William J. Munro +1
The idea of quantum texture has been recently proposed and used as a tool for quantifying coherences and for quantum gate identification. In this work we offer a study on its usage…
Non-Gaussianity in cat codes: global incompatibility and local geometric alignment with the magic resource
Yuwei Zhu, Seungbeom Chin, William J. Munro +1
Non-Gaussianity is an essential resource for genuine quantum advantages in continuous-variable quantum systems and is regarded as a counterpart of the magic resource in discrete-va…
Efficient Preparation of Graph States using the Quotient-Augmented Strong Split Tree
Nicholas Connolly, Shin Nishio, Dan E. Browne +2
Graph states are a key resource for measurement-based quantum computation and quantum networking, but state-preparation costs limit their practical use. Graph states related by loc…
Threshold (Q, P) Quantum Distillation
Shashank Gupta, William John Munro, Carlos Cid
Quantum distillation is the task of concentrating quantum correlations present in 'N' imperfect copies using free operations by involving all 'P' parties sharing the quantum correl…
