Security of Plug-and-Play QKD Arrangements with Finite Resources
Pedro J. Salas
The security of a passive plug-and-play QKD arrangement in the case of finite (resources) key lengths is analysed. It is assumed that the eavesdropper has full access to the channe…
Noise effect on Grover algorithm
Pedro J. Salas
The decoherence effect on Grover algorithm has been studied numerically through a noise modelled by a depolarizing channel. Two types of error are introduced characterizing the qub…
Simple fault-tolerant encoding over q-ary CSS quantum codes
Pedro J. Salas
CSS codes are a subfamily of stabilizer codes especially appropriate for fault-tolerant quantum computations. A very simple method is proposed to encode a general qudit when a Cald…
Quality of a Quantum Error Correcting Scheme and Memory Error Threshold Estimation
Pedro J. Salas
The error correcting capabilities of the Calderbank-Shor-Steane [[7,1,3]] quantum code, together with a fault-tolerant syndrome extraction by means of several ancilla states, have…
Error threshold estimation by means of the [[7,1,3]] CSS quantum code
Pedro J. Salas, Angel L. Sanz
The states needed in a quantum computation are extremely affected by decoherence. Several methods have been proposed to control error spreading. They use two main tools: fault-tole…
Effect of ancilla's structure on quantum error correction using the 7-qubit Calderbank-Shor-Steane code
Pedro J. Salas, Angel L. Sanz
In this work we discuss the ability of different types of ancillas to control the decoherence of a qubit interacting with an environment. The error is introduced into the numerical…
