All possible permutational symmetries of a quantum system
Ludovic Arnaud
We investigate the intermediate permutational symmetries of a system of qubits, that lie in between the perfect symmetric and antisymmetric cases. We prove that, on average, pure s…
Detecting faked continuous variable entanglement using one-sided device-independent entanglement witnesses
Bogdan Opanchuk, Ludovic Arnaud, Margaret D. Reid
We demonstrate the principle of one-sided device-independent continuous variable (CV) quantum information. In situations of no trust, we show by enactment how the use of standard C…
Exploring pure quantum states with maximally mixed reductions
Ludovic Arnaud, Nicolas J. Cerf
We investigate multipartite entanglement for composite quantum systems in a pure state. Using the generalized Bloch representation for n-qubit states, we express the condition that…
Distribution of Interference in the Presence of Decoherence
Ludovic Arnaud, Daniel Braun
We study the statistics of quantum interference for completely positive maps. We calculate analytically the mean interference and its second moment for finite dimensional quantum s…
Efficiency of Producing Random Unitary Matrices with Quantum Circuits
Ludovic Arnaud, Daniel Braun
We study the scaling of the convergence of several statistical properties of a recently introduced random unitary circuit ensemble towards their limits given by the circular unitar…
Distribution of interference in random quantum algorithms
Ludovic Arnaud, Daniel Braun
We study the amount of interference in random quantum algorithms using a recently derived quantitative measure of interference. To this end we introduce two random circuit ensemble…
