The Physics arXIv article Quantum cloaking makes molecules invisible said

Cloaking is surely the zeitgeist topic of the moment and for proof, you need look no further than the work of Jonas Fransson from the University of Upssala in Sweden and colleagues. This is a group who have who have applied the ideas of cloaking to the quantum world and come up trumps. the result is a design for a molecular cloak that could turn out to be extremely useful.
 
First what does it mean to see or not see a quantum object? Fransson and company say that seeing is equivalent to detecting quantum objects and in the case of molecules that means looking for the terahertz radiation they produced when they vibrate.
 
“We propose a method for detecting and manipulating quantum invisibility based on THz cloaking of molecular identity in coherent nanostructures,” says Fransson and friends.

Jonas Fransson, Ph.D. is Associate professor in Atomic, Molecular, and Condensed Matter Physics at Uppsala University, Sweden. He was previously at the Los Alamos National Laboratory.
 
His research interests include: non-equilibrium condensed matter physics, spectroscopic information in transport, strongly correlated materials, inelastic scattering effects, molecular electronics, noise spectroscopy, nano magnetism, spin dynamics, and spintronics.
 
His achievements include:

• Developed a diagrammatic Green function approach to treat nanoscale many-body systems under non-equilibrium conditions.
   
  
• Established a theory for asymmetries and negative differential conductance generated by strong electron correlations in nanoscale systems.
   
  
• Successfully provided a theoretical description and explanation for the so-called Pauli exclusion principle spin blockade in double quantum dot systems.
   
  
• Described combined nanomechanical-superconducting device that allows Cooper pair tunneling to interfere with the mechanical motion of a middle superconducting island.

Jonas authored Detection of spin reversal and nutations through current measurements, Subnanosecond switching of local spin-exchange coupled to ferromagnets, and Detection of exchange interaction in STM measurements through Fanolike interference effects, coauthored Quantum Detection and Invisibility in Coherent Nanostructures, Detection of the spin character of Fe(001) surface states by scanning tunneling microscopy: A theoretical proposal, Pauli spin blockade in carbon nanotube double quantum dots, Vibrational coherence in electron spin resonance in nanoscale oscillators, and Vibrating Superconducting Island in a Josephson Junction.
 
Jonas earned his Ph.D. in Physics with the thesis Non-orthogonality and Electron Correlations in Nanotransport. Spin- and Time-Dependent Currents at Uppsala University in 2002.
