Outline of Research at the Start |
Hybrid quantum systems (HQS) are a way to design composite systems with the properties one desires. In principle hybridization of distinct quantum systems allows us to exploit the best properties of these individual systems without their weaknesses or even design new properties. We will investigate novel nonlinear phenomenon in a hybrid quantum system to determine their properties and how they can be exploited. We will focus on the - Design models for HQS involving large ensembles - Exploration of superradiance and bistability in HQS - Novel quantum nonlinear phenomenon and future applications
|
Outline of Final Research Achievements |
Hybrid quantum systems (HQS) composed of multiple spin ensembles collectively coupled to an environment allow one ensemble to drive the second one into its excited steady state even when that ensemble starts in its ground state. We have explored quantum energy / correlation transport through a network of ensembles collectively pairwise coupled to environments. When our initial state is not symmetric with respect to the collective reservoir couplings, different parts of the quantum wave function decay at different rates resulting in populations arising in initially unoccupied nodes on much faster timescales than the single spin damping rates. This allows the migration of energy across in the network. The same approach allows entanglement generation between ensembles not even coupled to the same reservoir. We proposed several potential experimental implementations for these phenomena. Further we also used our simulator to explore driven phenomena in arrays of superconducting qubits.

Academic Significance and Societal Importance of the Research Achievements |
We have found new ways to transport quantum energy/correlations through a network on time scales much faster than what can be classical achieved. This provides the potential for new quantum thermodynamic based technologies including quantum batteries with significantly enhanced charging rates.
