A robust W-state encoding for linear quantum optics
Madhav Krishnan Vijayan, Austin P. Lund, Peter P. Rohde
Error-detection and correction are necessary prerequisites for any scalable quantum computing architecture. Given the inevitability of unwanted physical noise in quantum systems an…

Simple Bounds for One-shot Pure-State Distillation in General Resource Theories
Madhav Krishnan Vijayan, Eric Chitambar, Min-Hsiu Hsieh
We present bounds for distilling many copies of a pure state from an arbitrary initial state in a general quantum resource theory. Our bounds apply to operations that are able to g…

One-shot assisted concentration of coherence
Madhav Krishnan Vijayan, Eric Chitambar, Min-Hsiu Hsieh
We find one-shot bounds for concentration of maximally coherent states in the so called assisted scenario. In this setting, Bob is restricted to performing incoherent operations on…
