Infinite magic and the emergence of the continuum
Leo Shaposhnik, Lorenzo Leone, Lennart Bittel +3
Which features of a quantum state are needed for a relativistic quantum field theory to emerge from a lattice system? We address this question by establishing a quantitative relati…
Computational entanglement distillation beyond pure states: efficient protocols and fundamental limitations
Takeru Utsumi, Jacopo Rizzo, Ryuji Takagi +1
The information-theoretic approach to entanglement typically relies on arbitrarily many input copies and unboundedly complex operations; however, the available resources are constr…
Universal quantum coding
Jacopo Rizzo, Ludovico Lami, Filippo Girardi +2
Entanglement distillation from noisy bipartite states and reliable quantum communication over noisy channels are fundamental tasks in quantum information theory. Yet existing codin…
Universal magic state concentration
Jacopo Rizzo, Lorenzo Leone
Magic plays a dual role in quantum computation: it promotes stabilizer dynamics from efficient classical simulability to computational universality, but also challenges fault-toler…
Fermionic entropy: an efficiently measurable strong monotone for non-Gaussianity
Lorenzo Leone, Lennart Bittel
Fermionic Gaussian states form a central class of classically tractable quantum states, while fermionic non-Gaussianity provides the resource required to go beyond free-fermion dyn…
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…
