The unbearable hardness of deciding about magic

Lorenzo Leone, Jens Eisert, Salvatore F. E. Oliviero

Identifying the boundary between classical and quantum computation is a central challenge in quantum information. In multi-qubit systems, entanglement and magic are the key resourc…

The computational two-way quantum capacity

Johannes Jakob Meyer, Jacopo Rizzo, Asad Raza +3

Quantum channel capacities are fundamental to quantum information theory. Their definition, however, does not limit the computational resources of sender and receiver. In this work…

Computational relative entropy

Johannes Jakob Meyer, Asad Raza, Jacopo Rizzo +3

Our capacity to process information depends on the computational power at our disposal. Information theory captures our ability to distinguish states or communicate messages when i…

Operational interpretation of the Stabilizer Entropy

Lennart Bittel, Lorenzo Leone

Magic-state resource theory is a fundamental framework with far-reaching applications in quantum error correction and the classical simulation of quantum systems. Recent advances h…

Entanglement theory with limited computational resources

Lorenzo Leone, Jacopo Rizzo, Jens Eisert +1

The precise quantification of the ultimate efficiency in manipulating quantum resources lies at the core of quantum information theory. However, purely information-theoretic measur…

Constant Overhead Entanglement Distillation via Scrambling

Andi Gu, Lorenzo Leone, Kenneth Goodenough +1

High-fidelity quantum entanglement enables key quantum networking capabilities such as secure communication and distributed quantum computing, but long-distance entanglement distri…
