The exciting possibilities in the field of new quantum technologies extend far beyond the well-reported application of quantum computing. Precision timing, gravity sensors and imagers, cryptography, navigation, metrology, energy harvesting and recovery, biomedical sensors and imagers, and real-time optimisers all indicate the potential for quantum technologies to provide the basis of a technological...
We model a SQUID ring coupled to one or two electromagnetic field oscillator modes, each component being treated quantum mechanically. We show that the external flux on the SQUID ring can be used to control the exchange of energy, and level of entanglement, between the coupled systems. We then extend this model to include dissipation, and provide examples of the time evolution of these coupled, multicomponent...
This paper discusses two methods for generating quantum transitions between energy eigenstates in a model persistent current qubit. The alternatives are compared and their advantages and disadvantages are considered. Of particular concern is the backreaction of the qubit on the magnetic flux bias coils, used to control the qubit, due to the large effective currents at or near to a quantum mechanical...
. We explore the role played by the intrinsic decoherence in superconducting charge qubits in the presence of a microwave field applied as a magnetic flux. We study how the delayed creation of entanglement, which is opposite to the sudden death of entanglement, can be induced. We compute the time evolution of the population inversion, total correlation and entanglement, taking into account the junction...
