研究課題
Our primary focus in the last year of the project was to explore whether quantum correlations can be transported via HQS nonlinear effects. We showed that by utilising reservoir engineering that entanglement can be generated between two spins ensembles which are not coupled to each other or even coupled to the same reservoir. The degree of entanglement is maximised for a large number of spins in the central domain. Further the speed of entanglement generation is also maximised for a larger spin population in the central domain. Correlation transport shows a super radiant like enhancement. This in principle allows on to overcome the effects of dephasing present in each of the individual ensembles. Further entanglement generation is not limited to the three spin-domain case, but can also occur with a larger number of domains. This work was submitted to PRA in March 2023.A second aspect was associated with quantum simulations on NISQ processors. The current systems can perform universal simulation. We took this a significant step further and generated a many-body quantum state of matter that show collective effects and explored a practical simulation application of them. Investigating a 61-qubit device, we are able to create ergodic or localized states of matters. Given the collective dynamics of the system and individual qubit control, we were able to use quantum neuronal sensing process to efficiently classify two different types of many-body phenomena. This could be achieved by measuring only one qubit.
