Magic Secret Sharing: Threshold Control of Quantum Computational Power via GHZ Entanglement
Soumyojyoti Dutta, Tushar
We introduce Magic Secret Sharing (MSS), a quantum cryptographic primitive in which the secret is the computational capability of a quantum state rather than its classical descript…

A Phase-Space Geometric Measure of Magic in Qubit Systems
Soumyojyoti Dutta, Tushar
Magic -- the resource enabling quantum computational advantage beyond stabilizer circuits -- has a clean phase-space characterization in odd prime dimensions that qubits notoriousl…
