Random Gaussian Augmented Matrix Product States
Stavya Puri, Poetri Sonya Tarabunga, Piotr Sierant
Strong entanglement limits the reach of tensor-network descriptions of quantum many-body systems. We study Gaussian-augmented matrix product states (GAMPS), formed by applying a fr…
Spectral geometry of nonlocal stabilizer entropy
Piotr Sierant
Magic, or nonstabilizerness, is the resource that promotes stabilizer operations to universal quantum computation. For bipartite pure states, its component intrinsic to the correla…
Exact quantification of nonlocal magic
Piotr Sierant
Magic, or nonstabilizerness, is the resource that lifts Clifford circuits to universal quantum computation and has become a standard diagnostic of many-body states. For a state sha…
Theory of Magic Phase Transitions in Encoding-Decoding Circuits
Piotr Sierant, Xhek Turkeshi
Quantum magic resources, or nonstabilizerness, are a central ingredient for universal quantum computation. In noisy many-body systems, the interplay between these resources and err…
Limits of Clifford Disentangling in Tensor Network States
Sergi Masot-Llima, Piotr Sierant, Paolo Stornati +1
Tensor network methods leverage the limited entanglement of quantum states to efficiently simulate many-body systems. Alternatively, Clifford circuits provide a framework for handl…
Computing quantum magic of state vectors
Piotr Sierant, Jofre Vallès-Muns, Artur Garcia-Saez
Non-stabilizerness, also known as ``magic,'' quantifies how far a quantum state departs from the stabilizer set. It is a central resource behind quantum advantage and a useful prob…
