Quantum probe hyperpolarisation of molecular nuclear spins

Nature Communications, 2018
Molecules with ‘hyperpolarised’ nuclear spins can be used to improve MRI performance but require an efficient polarisation method. Broadway et al. demonstrate a quantum control protocol using a nitrogen vacancy centre inside a diamond to hyperpolarise ...

Exclusive quantum channels in quantum networks [PDF]

arXiv, 2014
Quantum state can be teleported to a remote site by only local measurement and classical communication if the prior Einstein-Podolsky-Rosen quantum channel is available between the sender and the receiver. Those quantum channels shared by multiple nodes can constitute a quantum network.

Broadband Chiroptics with Twist‐stacked Hyperbolic Conducting Polymer Thin Films

Advanced Materials, Volume 37, Issue 16, April 23, 2025.
Anisotropic conducting polymer films can exhibit optical hyperbolic properties which here are found connected to large birefringence and linear dichroism. Off‐axis twist‐stacking of only two such subwavelength films can therefore enable large and broadband circular dichroism (CD), with CD bandwidth closely related to the hyperbolic bandwidth. The study
