Analytical and Compressed Simulation of Noisy Stabilizer Circuits
Paul Aigner, Jasmin Matti, Maria Flors Mor-Ruiz +2
We develop analytical and algorithmic techniques that enable efficient simulation of a broad class of noisy stabilizer circuits. We derive closed-form expressions of expectation va…
Universal Nested Quantum Switch
Jorge Miguel-Ramiro, Maria Flors Mor-Ruiz, Wolfgang Dür
The quantum switch is a basic network primitive that allows one to connect multiple nodes in a quantum network via a central node. We show that the same functionality can be achiev…
Qudit Noisy Stabilizer Formalism
Paul Aigner, Maria Flors Mor-Ruiz, Wolfgang Dür
We introduce the qudit Noisy Stabilizer Formalism, a framework for efficiently describing the evolution of stabilizer states in prime-power dimensions subject to generalized Pauli-…
Merging-Based Quantum Repeater
Maria Flors Mor-Ruiz, Jorge Miguel-Ramiro, Julius Wallnöfer +2
We introduce an alternative approach for the design of quantum repeaters based on generating entangled states of growing size. The scheme utilizes quantum merging operations, also…
Imperfect quantum networks with tailored resource states
Maria Flors Mor-Ruiz, Julius Wallnöfer, Wolfgang Dür
Entanglement-based quantum networks exhibit a unique flexibility in the choice of entangled resource states that are then locally manipulated by the nodes to fulfill any request in…
Resource-efficient fault-tolerant one-way quantum repeater with code concatenation
Kah Jen Wo, Guus Avis, Filip Rozpędek +6
One-way quantum repeaters where loss and operational errors are counteracted by quantum error correcting codes can ensure fast and reliable qubit transmission in quantum networks.…
