Entanglement Dynamics in Monitored Systems and the Role of Quantum Jumps
Youenn Le Gal, Xhek Turkeshi, Marco Schirò
Monitored quantum many-body systems display a rich pattern of entanglement dynamics, which is unique to this non-unitary setting. This work studies the effect of quantum jumps on t…
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…
Entanglement and absorbing state transitions in -dimensional stabilizer circuits
Piotr Sierant, Xhek Turkeshi
We study the influence of feedback operations on the dynamics of -dimensional monitored random quantum circuit. Competition between unitary dynamics and measurements leads t…
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…
Entanglement Growth and Minimal Membranes in Random Unitary Circuits
Piotr Sierant, Marco Schirò, Maciej Lewenstein +1
Understanding the nature of entanglement growth in many-body systems is one of the fundamental questions in quantum physics. Here, we study this problem by characterizing the entan…
Density and current statistics in boundary-driven monitored fermionic chains
Xhek Turkeshi, Lorenzo Piroli, Marco Schirò
We consider a one-dimensional system of non-interacting fermions featuring both boundary driving and continuous monitoring of the bulk particle density. Due to the measurements, th…
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…
Purification Timescales in Monitored Fermions
Hugo Lóio, Andrea De Luca, Jacopo De Nardis +1
We investigate the crucial role played by a global symmetry in the purification timescales and the phase transitions of monitored free fermionic systems separating a mixed and a pu…
