Extracting randomness from magic quantum states

Understand

Magic quantum states (non-stabilizer states) play a pivotal role in fault-tolerant quantum computation.

• Simultaneously, random resources have emerged as a key element in various randomized techniques within contemporary quantum science.
• In this study, we establish a direct connection between these two notions.
• More specifically, our research demonstrates that when a subsystem of a quantum state is measured, the resultant unmeasured part of the system can exhibit a high degree of randomness that can be enhanced by the inherent correlations of the underlying magic quantum state.
