Multipartite entanglement structure of monitored quantum circuits
Arnau Lira-Solanilla, Xhek Turkeshi, Silvia Pappalardi
Monitored quantum circuits have attracted significant interest as an example of synthetic quantum matter, intrinsically defined by their quantum information content. Here, we propo…
Anticoncentration and nonstabilizerness spreading under ergodic quantum dynamics
Emanuele Tirrito, Xhek Turkeshi, Piotr Sierant
Quantum state complexity metrics, such as anticoncentration and nonstabilizerness, or ``magic'', offer key insights into many-body physics, information scrambling, and quantum comp…
Anticoncentration and state design of random tensor networks
Guglielmo Lami, Jacopo De Nardis, Xhek Turkeshi
We investigate quantum random tensor network states where the bond dimensions scale polynomially with the system size, . Specifically, we examine the delocalization properties o…
Magic Resources of the Heisenberg Picture
Neil Dowling, Pavel Kos, Xhek Turkeshi
We study a non-stabilizerness resource theory for operators, which is dual to that describing states. We identify that the stabilizer Rényi entropy analog in operator space is a go…
Approximate inverse measurement channel for shallow shadows
Riccardo Cioli, Elisa Ercolessi, Matteo Ippoliti +2
Classical shadows are a versatile tool to probe many-body quantum systems, consisting of a combination of randomised measurements and classical post-processing computations. In a r…
Magic spreading in random quantum circuits
Xhek Turkeshi, Emanuele Tirrito, Piotr Sierant
Magic is the resource that quantifies the amount of beyond-Clifford operations necessary for universal quantum computing. It bounds the cost of classically simulating quantum syste…
Quantum Mpemba Effect in Random Circuits
Xhek Turkeshi, Pasquale Calabrese, Andrea De Luca
The essence of the Mpemba effect is that non-equilibrium systems may relax faster the further they are from their equilibrium configuration. In the quantum realm, this phenomenon a…
Monitored long-range interacting systems: spin-wave theory for quantum trajectories
Zejian Li, Anna Delmonte, Xhek Turkeshi +1
Measurement-induced phases exhibit unconventional dynamics as emergent collective phenomena, yet their behavior in tailored interacting systems -- crucial for quantum technologies…
Hilbert space delocalization under random unitary circuits
Xhek Turkeshi, Piotr Sierant
Unitary dynamics of a quantum system initialized in a selected basis state yields, generically, a state that is a superposition of all the basis states. This process, associated wi…
