Quantum error detection in qubit-resonator star architecture

Florian Vigneau, Sourav Majumder, Aniket Rath +13

Achieving industrial quantum advantage is unlikely without the use of quantum error correction (QEC). Other QEC codes beyond surface code are being experimentally studied, such as…

Entanglement barrier and its symmetry resolution: theory and experiment

Aniket Rath, Vittorio Vitale, Sara Murciano +6

The operator entanglement (OE) is a key quantifier of the complexity of a reduced density matrix. In out-of-equilibrium situations, e.g. after a quantum quench of a product state,…
