Noisy Stabilizer Formalism
Maria Flors Mor-Ruiz, Wolfgang Dür
Despite the exponential overhead to describe general multi-qubit quantum states and processes, efficient methods for certain state families and operations have been developed and u…
Nondestructive Verification of Entangled States via Fidelity Witnessing
Ferran Riera-Sàbat, Jorge Miguel-Ramiro, Wolfgang Dür
Assessing the quality of an ensemble of noisy entangled states is a central task in quantum information processing. Usually this is done by measuring and hence destroying multiple…
A Quantum Simulator Based on Locally Controlled Logical Systems
Ferran Riera-Sàbat, Pavel Sekatski, Wolfgang Dür
In a digital quantum simulator, basic two-qubit interactions are manipulated by means of fast local control operations to establish a desired target Hamiltonian. Here we consider a…
Remotely Controlled Entanglement Generation
Ferran Riera-Sàbat, Pavel Sekatski, Wolfgang Dür
We consider a system of multiple qubits without any quantum control. We show that one can mediate entanglement between different subsystems in a controlled way by adding a (locally…
Collective Operations Can Exponentially Enhance Quantum State Verification
Jorge Miguel-Ramiro, Ferran Riera-Sàbat, Wolfgang Dür
Maximally entangled states are a key resource in many quantum communication and computation tasks, and their certification is a crucial element to guarantee the desired functionali…
