Dissipative preparation of injective tensor network states
Drishti Baruah, Georgios Styliaris, J. Ignacio Cirac +1
The preparation of tensor network states is a fundamental prerequisite for a wide range of quantum simulation tasks. While many unitary protocols for preparing these states have be…
Quantum Memory and Autonomous Computation in Two Dimensions
Gesa Dünnweber, Georgios Styliaris, Rahul Trivedi
Standard approaches to quantum error correction (QEC) require active maintenance using measurements and classical processing. Passive QEC, by contrast, has so far been established…
Phases of matrix-product states with symmetries and measurements: Finite nilpotent groups
David Gunn, Georgios Styliaris, Barbara Kraus +1
We study phases of one-dimensional matrix-product states (MPS) when transformations are restricted to symmetric local circuits supplemented with symmetric measurements and feedforw…
Average-computation benchmarking for local expectation values in digital quantum devices
Flavio Baccari, Pavel Kos, Georgios Styliaris
As quantum devices progress towards a quantum advantage regime, they become harder to benchmark. A particularly relevant challenge is to assess the quality of the whole computation…
Structure and Classification of Matrix Product Quantum Channels
Giorgio Stucchi, J. Ignacio Cirac, Rahul Trivedi +1
We develop a framework for Matrix Product Quantum Channels (MPQCs), a one-dimensional tensor-network description of completely positive, trace-preserving maps. We focus on translat…
Adiabatic quantum state preparation in integrable models
Maximilian Lutz, Lorenzo Piroli, Georgios Styliaris +1
We propose applying the adiabatic algorithm to prepare high-energy eigenstates of integrable models on a quantum computer. We first review the standard adiabatic algorithm to prepa…
