Scientists from the University of Rochester have underlined their after study that is aimed at understanding thin-film like nanophotonic devices that could well advance the current application list for metrology, sensing, and quantum networks. They further assert their findings by applying their current set of standards into extending an incredibly large bandwidth using the thin-film structure.

The team notes that quantum entanglement occurs when two quantum particles are connected to each other even when they are present million of miles apart. When this entanglement process occurs, a wide range of interesting possibilities emerge that could include engaging of the photon’s frequencies and bandwidth of which the team further explored the possibilities. This current breakthrough led to enhanced sensitivity and resolution for experiments in metrology and sensing in terms of spectroscopy, non-linear microscopy, and quantum optical coherence tomography.

Additionally, higher dimensional encoding of information into quantum networks for information processing and communications can be further explored. This work is expected to pave the way for producing ultrabroadband quantum entanglement on a nanophotonic chip.

Furthermore, this team demonstrates the power of nanotechnology for developing the next generation of quantum devices in terms of communication, computing, and sensing. The team notes that the current generation of broadband entanglement of light have the ability to restore light for dividing a bulk crystal into small section with each variation being slightly different in terms of optical properties of the photon pairs. These frequencies are then added to give the illusion of a larger bandwidth. However, this effect is achieved on the back of a reduced brightness measures and decreased purity of the photons. A tradeoff is always present between the generated photo pair and a single titular choice has to be made between the latter. The team circumnavigated this tradeoff with their dispersion engineering technique in order to achieve a record-high bandwidth and a record-high brightness.
