Tremendous advances have been made in the last two decades in precision ‘Quantum’ technologies and techniques in multiple disciplines e.g. cavity electrodynamics, atomic

beam interferometry, SQUIDS, quantum optical “squeezed state” techniques for noise-free single photon detection, qubit-based quantum entanglement techniques, high-Q superconducting cavities, precision NMR detection via designer materials, etc.  These advances promise to enable transformational research in fundamental and information science using ultra-sensitive probes to explore very “weak effects” on a laboratory scale as well as exploit “quantum entanglement” for advanced computing.  These weak effects are manifest everywhere in nature in material and living systems from the laboratory to outer space.  Potential “mezzo-scale” experiments and facilities can be envisaged using “quantum sensors” to search for ultra-weak physical, chemical or biological signals of fundamental significance to the material and living world around us, to explore the hidden matter and energy in the “dark” universe and advance information science.  This talk will illustrate this potential via a few exciting examples discussed at the recent DOE Round Table in USA, February 2016.

Slides of this talk will be available soon.
