Modern physics has contributed
to the development of powerful instruments and diagnostic tools
for biology and medicine, with a direct impact on both our well
being and life expectancy. Today, it is timely to ask if the novel
field of quantum information is ready to provide new methods for
the life sciences. This project makes a step in this direction,
introducing non-invasive quantum techniques for experimental biology,
with potential applications to biomedical imaging. My goal is
to show how quantum correlations (e.g., entanglement) can be exploited
to realize a fully non-invasive form of quantum spectroscopy,
which can be safely applied to fragile materials, such as photo-degradable
biological samples (DNA/RNA) or in-vivo human tissues. These objectives
are not met in today’s biology labs, where UV-light photometry
heavily damages DNA/RNA samples, or in public hospitals, where
X-ray scans expose patients to significant radiation doses. The
basic rationale behind the use of quantum correlations relies
on their superior capacity to detect small variations in the absorption
properties of the materials, even when only a few photons are
employed. By exploiting this remarkable feature, I study the possibility
of non-invasive testing of biological samples. My central task
is the design of a practical model of a quantum-enhanced photometer
which is fully based on continuous-variable systems. The realization
of such an instrument would allow for real-time continuous measurements
of organic molecules and nucleic acids without any photo-degradation.

I am a biologist (PhD 2010) and computer scientist
(PhD 2016) actively working in the field quantum technologies.
My background is both experimental (molecular biology) and theoretical
(quantum information theory). My overall aspiration is to apply
quantum physics to improve the techniques and instrumentation
that are currently used in biology and medicine.
