Limits on broadcasting non-stabilizerness through unrestricted operations
Rivu Gupta, Tanoy Kanti Konar, Ayan Patra +1
In the resource theory of non-stabilizerness, we prove that stabilizer operations cannot replicate or broadcast the "magic" resource of all quantum states in an arbitrary finite di…

Qubit magic-breaking channels
Ayan Patra, Rivu Gupta, Alessandro Ferraro +1
We develop a notion of quantum channels that can make states useless for universal quantum computation by destroying their magic (non-stabilizerness) - we refer to them as magic-br…
