The non-stabilizerness of fermionic Gaussian states
Mario Collura, Jacopo De Nardis, Vincenzo Alba +1
We introduce an efficient method to quantify nonstabilizerness in fermionic Gaussian states, overcoming the long-standing challenge posed by their extensive entanglement. Using a p…
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…
Clifford Dressed Time-Dependent Variational Principle
Antonio Francesco Mello, Alessandro Santini, Guglielmo Lami +2
We propose an enhanced Time-Dependent Variational Principle (TDVP) algorithm for Matrix Product States (MPS) that integrates Clifford disentangling techniques to efficiently manage…
Variational ground-state quantum adiabatic theorem
Bojan Žunkovič, Pietro Torta, Giovanni Pecci +2
We present a variational quantum adiabatic theorem, which states that, under certain assumptions, the adiabatic dynamics projected onto a variational manifold follow the instantane…
Estimating Non-Stabilizerness Dynamics Without Simulating It
Alessio Paviglianiti, Guglielmo Lami, Mario Collura +1
We introduce the Iterative Clifford Circuit Renormalization (ICCR), a novel technique designed to efficiently handle the dynamics of non-stabilizerness (a.k.a. quantum magic) in ge…
Quantum State Designs with Clifford Enhanced Matrix Product States
Guglielmo Lami, Tobias Haug, Jacopo De Nardis
Nonstabilizerness, or `magic', is a critical quantum resource that, together with entanglement, characterizes the non-classical complexity of quantum states. Here, we address the p…
Retrieving non-stabilizerness with Neural Networks
Antonio Francesco Mello, Guglielmo Lami, Mario Collura
Quantum computing's promise lies in its intrinsic complexity, with entanglement initially heralded as its hallmark. However, the quest for quantum advantage extends beyond entangle…
Learning the stabilizer group of a Matrix Product State
Guglielmo Lami, Mario Collura
We present a novel classical algorithm designed to learn the stabilizer group -- namely the group of Pauli strings for which a state is a eigenvector -- of a given Matrix P…
