Assessing quantum error correction: fidelity and entanglement measures with application to photonic codes
Ricardo Wickert, Peter van Loock
By interpreting the well-known, qualitative criteria for the existence of quantum error correction (QEC) codes by Knill and Laflamme from a quantitative perspective, we propose a f…
Quantum error correction and detection: quantitative analysis of a coherent-state amplitude damping code
Ricardo Wickert, Peter van Loock
We re-examine a non-Gaussian quantum error correction code designed to protect optical coherent-state qubits against errors due to an amplitude damping channel. We improve on a pre…
Efficient Heralding of Photonic Qubits with Apllications to Device Independent Quantum Key Distribution
David Pitkänen, Xiongfeng Ma, Ricardo Wickert +2
We present an efficient way of heralding photonic qubit signals using linear optics devices. First we show that one can obtain asymptotically perfect heralding and unit success pro…
Entanglement properties of optical coherent states under amplitude damping
Ricardo Wickert, Nadja Kolb Bernardes, Peter van Loock
Through concurrence, we characterize the entanglement properties of optical coherent-state qubits subject to an amplitude damping channel. We investigate the distillation capabilit…
