A Numerical Analysis of the Modified Kirk's Formula and Applications to Spread Option Pricing Approximations a numerical analysis of the modified kirk's formula and applications to spread option pricing approximations
Suren Harutyunyan, AdriÀ Masip BorrÀs
In this paper we study recent developments in the approximation of the spread option pricing. As the Kirkś Approximation is extremely flawed in the cases when the correlation is ve…
Detecting entanglement of two electron spin qubits with witness operators
A. Borras, M. Blaauboer
We propose a scheme for detecting entanglement between two electron spin qubits in a double quantum dot using an entanglement witness operator. We first calculate the optimal confi…
Some features of the state-space trajectories followed by robust entangled four-qubit states during decoherence
A. P. Majtey, A. Borras, A. R. Plastino +2
In a recent work (Borras et al., Phys. Rev. A {\bf 79}, 022108 (2009)), we have determined, for various decoherence channels, four-qubit initial states exhibiting the most robust p…
Robustness of Highly Entangled Multi-Qubit States Under Decoherence
A. Borras, A. P. Majtey, A. R. Plastino +2
We investigate the decay of entanglement, due to decoherence, of multi-qubit systems that are initially prepared in highly (in some cases maximally) entangled states. We assume tha…
Efficient generation of random multipartite entangled states using time optimal unitary operations
A. Borras, A. Majtey, M. Casas
We review the generation of random pure states using a protocol of repeated two qubit gates. We study the dependence of the convergence to states with Haar multipartite entanglemen…
Jensen Shannon divergence as a measure of the degree of entanglement
A. P. Majtey, A. Borras, M. Casas +2
The notion of distance in Hilbert space is relevant in many scenarios. In particular, distances between quantum states play a central role in quantum information theory. An appropr…
