Parity-unfolded distillation architecture for noise-biased platforms
Konstantin Tiurev, Christoph Fleckenstein, Christophe Goeller +6
We introduce the parity-unfolded architecture, a fault-tolerant quantum computing scheme that relies on direct preparation and teleportation of small-angle rotations …
Optimal Decoder for the Error Correcting Parity Code
Konstantin Tiurev, Christophe Goeller, Leo Stenzel +4
We present a two-step decoder for the parity code and evaluate its performance in code-capacity and faulty-measurement settings. For noiseless measurements, we find that the decodi…
The domain wall color code
Konstantin Tiurev, Arthur Pesah, Peter-Jan H. S. Derks +4
We introduce the domain wall color code, a new variant of the quantum error-correcting color code that exhibits exceptionally high code-capacity error thresholds for qubits subject…
Correcting non-independent and non-identically distributed errors with surface codes
Konstantin Tiurev, Peter-Jan H. S. Derks, Joschka Roffe +2
A common approach to studying the performance of quantum error correcting codes is to assume independent and identically distributed single-qubit errors. However, the available exp…
Entangling a Hole Spin with a Time-Bin Photon: A Waveguide Approach for Quantum Dot Sources of Multi-Photon Entanglement
Martin Hayhurst Appel, Alexey Tiranov, Simon Pabst +10
Deterministic sources of multi-photon entanglement are highly attractive for quantum information processing but are challenging to realize experimentally. In this paper, we demonst…
Fidelity measurement of a multiqubit cluster state with minimal effort
Konstantin Tiurev, Anders S. Sørensen
The size of the Hilbert space for a multiqubit state scales exponentially with the number of constituent qubits. Often this leads to a similar exponential scaling of the experiment…
Fidelity of time-bin entangled multi-photon states from a quantum emitter
Konstantin Tiurev, Pol Llopart Mirambell, Mikkel Bloch Lauritzen +4
We devise a mathematical framework for assessing the fidelity of multi-photon entangled states generated by a single solid-state quantum emitter, such as a quantum dot or a nitroge…
High-fidelity multi-photon-entangled cluster state with solid-state quantum emitters in photonic nanostructures
Konstantin Tiurev, Martin Hayhurst Appel, Pol Llopart Mirambell +4
We propose a complete architecture for deterministic generation of entangled multiphoton states. Our approach utilizes periodic driving of a quantum-dot emitter and an efficient li…
