Measurments-induced quantum phase transitions
Dragi Karevski, Michele Coppola, Emanuele Tirrito +1
Dynamical phase transitions induced by local projective measurements have attracted a lot of attention in the past few years. It has been in particular argued that measurements may…
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…
Stabilizer disentangling of conformal field theories
Martina Frau, Poetri Sonya Tarabunga, Mario Collura +2
Understanding how entanglement can be reduced through simple operations is crucial for both classical and quantum algorithms. We investigate the entanglement properties of lattice…
A nonstabilizerness monotone from stabilizerness asymmetry
Poetri Sonya Tarabunga, Martina Frau, Tobias Haug +2
We introduce a nonstabilizerness monotone which we name basis-minimised stabilizerness asymmetry (BMSA). It is based on the notion of -asymmetry, a measure of how much a certain…
Disentangling magic states with classically simulable quantum circuits
Gerald E. Fux, Benjamin Béri, Rosario Fazio +1
We show that states obtained from deep random Clifford circuits doped with non-Clifford phase gates (including T-gates and -gates) can be disentangled completely…
Nonstabilizerness in U(1) lattice gauge theory
Pedro R. Nicácio Falcão, Poetri Sonya Tarabunga, Martina Frau +3
We present a thorough investigation of nonstabilizerness - a fundamental quantum resource that quantifies state complexity within the framework of quantum computing - in a one-dime…
Magic transition in measurement-only circuits
Poetri Sonya Tarabunga, Emanuele Tirrito
Magic, also known as nonstabilizerness, quantifies the distance of a quantum state to the set of stabilizer states, and it serves as a necessary resource for potential quantum adva…
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…
Non-stabilizerness versus entanglement in matrix product states
M. Frau, P. S. Tarabunga, M. Collura +2
In this paper, we investigate the relationship between entanglement and non-stabilizerness (also known as magic) in matrix product states (MPSs). We study the relation between magi…
Nonstabilizerness via matrix product states in the Pauli basis
Poetri Sonya Tarabunga, Emanuele Tirrito, Mari Carmen Bañuls +1
Nonstabilizerness, also known as ``magic'', stands as a crucial resource for achieving a potential advantage in quantum computing. Its connection to many-body physical phenomena is…
