Quantum Simulation of Noisy Quantum Networks
Ferran Riera-Sàbat, Jorge Miguel-Ramiro, Wolfgang Dür
Complex quantum networks are not only hard to establish, but also difficult to simulate due to the exponentially growing state space and noise-induced imperfections. In this work,…
A modular entanglement-based quantum computer architecture
Ferran Riera-Sàbat, Wolfgang Dür
We propose a modular quantum computation architecture based on utilizing multipartite entanglement. Each module consists of a small-scale quantum computer comprising data, memory a…
Quantum computation with logical gates between hot systems
Ferran Riera-Sàbat, Pavel Sekatski, Wolfgang Dür
We consider quantum computer architectures where interactions are mediated between hot qubits that are not in their mechanical ground state. Such situations occur, e.g., when not c…
Quantum Repeater for W states
Jorge Miguel-Ramiro, Ferran Riera-Sàbat, Wolfgang Dür
W states are a valuable resource for various quantum information tasks, and several protocols to generate them have been proposed and implemented. We introduce a quantum repeater p…
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…
