Anticoncentration and State Design of Doped Real Clifford Circuits and Tensor Networks
Beatrice Magni, Markus Heinrich, Lorenzo Leone +1
We investigate the statistical properties of orthogonal, or real, Clifford circuits doped with magic and imaginary resources. By developing the Weingarten calculus for the real Cli…
Liouvillian Exceptional Points in Quantum Brickwork Circuits
Vladislav Popkov, Mario Salerno
We demonstrate that Liouvillian exceptional points (LEPs), previously explored only in continuous Lindbladian dynamics, also emerge in discrete brickwork completely positive trace-…
Adaptively secure unitary designs with constant non-Clifford cost
Lennart Bittel, Lorenzo Leone
Randomness is a fundamental resource in quantum information, with crucial applications in cryptography, algorithms, and error correction. A central challenge is to construct unitar…
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…
Non-Clifford Cost of Random Unitaries
Lorenzo Leone, Salvatore F. E. Oliviero, Alioscia Hamma +2
Recent years have enjoyed a strong interest in exploring properties and applications of random quantum circuits. In this work, we explore the ensemble of -doped Clifford circuit…
Multiphoton quantum simulation of the generalized Hopfield memory model
Gennaro Zanfardino, Stefano Paesani, Luca Leuzzi +5
In the present work, we introduce, develop, and investigate a connection between multiphoton quantum interference, a core element of emerging photonic quantum technologies, and Hop…
