Quantum multiplexing with optical coherent states
Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada
In this paper, we propose a novel quantum multiple access technique based on optical coherent states. The information of several coherent state optical qubits is combined into a si…
Quantum Multiplexing with the Orbital Angular Momentum of light
Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada
The orbital angular momentum, OAM, of photons offers a suitable support to carry the quantum data of multiple users. We present two novel optical setups that send the information o…
Quantum interrogation logic gates
Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada
Quantum interrogation can be used as a basic resource for quantum information. This paper presents its applications to entanglement creation and to optical quantum computation. The…
Quantum Multiplexing for Quantum Computer Networks
Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada
In communication networks many different channels must share a limited amount of resources. In order to allow for multiple simultaneous communications, multiple access techniques a…
An Interaction-Free Quantum Shutter
Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada
We give a proposal for the physical implementation of a quantum shutter. This shutter is a mechanism able to close the passage of light through a slit when present. As it must be a…
Delayed commutation in quantum computer networks
Juan Carlos Garcia-Escartin, Pedro Chamorro-Posada
In the same way that classical computer networks connect and enhance the capabilities of classical computers, quantum networks can combine the advantages of quantum information and…
