Optimal encoding of two dissipative interacting qubits
G. Di Bello, G. De Filippis, A. Hamma +1
We investigate a system of two coupled qubits interacting with an Ohmic bath as a physical model for the implementation of one logical qubit. In this model, the interaction with th…
Scrambling Power of Soft Photons
Xuan-Lin Su, Alioscia Hamma, Antonino Marciano
Observable scattering processes entail emission-absorption of soft photons. As these degrees of freedom go undetected, some information is lost. Whether some of this information ca…
Learning t-doped stabilizer states
Lorenzo Leone, Salvatore F. E. Oliviero, Alioscia Hamma
In this paper, we present a learning algorithm aimed at learning states obtained from computational basis states by Clifford circuits doped with a finite number of -gates. T…
Logarithmic light cone, slow entanglement growth, and quantum memory
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +4
Effective light cones, characterized by Lieb-Robinson bounds, emerge in nonrelativistic local quantum systems. Here, we present several analytical results derived from logarithmic…
Stabilizer entropy dynamics after a quantum quench
Davide Rattacaso, Lorenzo Leone, Salvatore F. E. Oliviero +1
Stabilizer entropies (SE) measure deviations from stabilizer resources and as such are a fundamental ingredient for quantum advantage. In particular, the interplay of SE and entang…
The scrambling power of gravity in black hole radiation
Xuan-Lin Su, Alioscia Hamma, Antonino Marciano
The black hole information paradox remains a profound challenge in theoretical physics. Among the proposed resolutions, the soft-hair approach stands out for its independence from…
Quantifying non-stabilizerness through entanglement spectrum flatness
Emanuele Tirrito, Poetri Sonya Tarabunga, Gugliemo Lami +6
Non-stabilizerness - also colloquially referred to as magic - is the a resource for advantage in quantum computing and lies in the access to non-Clifford operations. Developing a c…
Phase transition in Stabilizer Entropy and efficient purity estimation
Lorenzo Leone, Salvatore F. E. Oliviero, Gianluca Esposito +1
Stabilizer Entropy (SE) quantifies the spread of a state in the basis of Pauli operators. It is a computationally tractable measure of non-stabilizerness and thus a useful resource…
