Pauli Spectrum and Non-stabilizerness of Typical Quantum Many-Body States
Xhek Turkeshi, Anatoly Dymarsky, Piotr Sierant
An important question of quantum information is to characterize genuinely quantum (beyond-Clifford) resources necessary for universal quantum computing. Here, we use the Pauli spec…
Enhanced Entanglement in the Measurement-Altered Quantum Ising Chain
Alessio Paviglianiti, Xhek Turkeshi, Marco Schirò +1
Understanding the influence of measurements on the properties of many-body systems is a fundamental problem in quantum mechanics and for quantum technologies. This paper explores h…
Interactions and integrability in weakly monitored Hamiltonian systems
Bo Xing, Xhek Turkeshi, Marco Schiró +2
Interspersing unitary dynamics with local measurements results in measurement-induced phases and transitions in many-body quantum systems. When the evolution is driven by a local H…
Error-resilience Phase Transitions in Encoding-Decoding Quantum Circuits
Xhek Turkeshi, Piotr Sierant
Understanding how errors deteriorate the information encoded in a many-body quantum system is a fundamental problem with practical implications for quantum technologies. Here, we i…
Many-body Dynamics in Monitored Atomic Gases Without Post-Selection Barrier
Gianluca Passarelli, Xhek Turkeshi, Angelo Russomanno +3
We study the properties of a monitored ensemble of atoms driven by a laser field and in the presence of collective decay. The properties of the quantum trajectories describing the…
Measuring nonstabilizerness via multifractal flatness
Xhek Turkeshi, Marco Schirò, Piotr Sierant
Universal quantum computing requires nonstabilizer (magic) quantum states. Quantifying the nonstabilizerness and relating it to other quantum resources is vital for characterizing…
