Recent rapid advancements in nanofabrication technologies have widened the realm of possibilities in nanophotonics, nonlinear and sub-wavelength optics. Realizing nonlinear optics in subwavelength scale paves the way for low cost integrated photonics. Ultra-high-Q photonic crystal nanocavities and nanostructured materials are examples of such structures. Those structures offer very small mode volume guaranteeing highly enhanced field intensity.

An approach to quantum random number generation based on unambiguous quantum state discrimination (USD) is developed. We consider a prepare-and-measure protocol, where two non-orthogonal quantum states can be prepared, and a measurement device aims at unambiguously discriminating between them.

I will present a realization of a great photon pair source based on parametric down-conversion, and discuss a not-so-great limit to the performance of photon pair sources in general. The former is a fully fiber-coupled waveguide pair source with 46% raw heralding efficiency, and no optical alignment required. The latter restricts the achievable heralding efficiency, when spectrally filtering the photons to increase the purity.

Motivated by their necessity for most fault-tolerant quantum computation schemes, we formulate a resource theory for magic states. We first show that robustness of magic is a well-behaved magic monotone that operationally quantifies the classical simulation overhead for a Gottesman-Knill type scheme using ancillary magic states. Our framework subsequently finds immediate application in the task of synthesizing non-Clifford gates using magic states.

“He who is good with a hammer thinks everything is a nail.”

How does one sell security? How does one commercialize such nebulous concepts such as “Trust”, “Security” and “Cryptography”?  Cryptography, which is just one building block of security, is based on other more abstract building blocks such as algorithms which have a foundation on hard mathematical problems.

Quantum mechanics reveals that at its core, the world is not as it seems – it is far more interesting.
 
In the quantum world, outcomes are counter-intuitive, differing from what we expect based on our everyday experiences. The particle physicist Richard Feynman remarked that this means we seem to have to walk “a logical tightrope” when we talk about a quantum system.

The invention of quantum physics in the early 20th century forced scientists to reconsider many cherished ideas from classical physics, leading to revolutionary changes in our scientific and philosophical understanding of the universe. Quantum phenomena have also proven to be a rich source of metaphors and inspiration for fiction.
