Although focus upon this material has diminished, superfluid Helium-3 (3He) remains by far the best-understood unconventional superconductor (superfluid). Moreover, it has recently re-emerged as a system of great theoretical interest because it is the only known odd-parity ‘topological' superfluid. In this reincarnation, it is a candidate for study of the zero-energy Bogoliubov states at superfluid boundaries since they can be viewed as ‘Majorana’ fermions.

A game where Alice and Bob are separated, forbidden
to comunicate, receive inputs from the same input set I, and produce
outputs from the same output set O is called synchronous provided that
any time Alice and Bob receive the same input, they are required to

The transverse spatial degree of freedom of light offers great potential to explore quantum informational tasks and interesting features of single photons and quantum entanglement. We developed novel methods to generate, investigate, and verify the entanglement of complex spatial structures. With these methods, we were able to entangle photons with up to 300 quanta of orbital angular momentum (OAM) and to image the effect of entanglement of twisted photons in real-time.

Strong interactions between light and atoms at the single-quantum level are an important ingredient for quantum technologies, and for studies of complex many-particle quantum systems. In this talk, I will describe the development of a novel experimental platform that allows for trapping a single rubidium atom in the evanescent mode of a nano-fabricated optical cavity with sub-wavelength dimensions.

This event has been postponed and will be rescheduled for a later date.

The RuggedCom Story – “A Tale of Canadian Technology Entrepreneurship & Crossing the Chasm”

In 2001 RuggedCom was a fledging startup. A decade later it was bought by Siemens for nearly half a billion dollars. Mr. Pozzuoli, its founder, will discuss its path to success and the role played in that success by the Canadian experience and the strategies outlined in Geoffrey Moore’s iconic book “Crossing the Chasm”.

Optical coherence tomography (OCT) has been a key technology in medicine and biology [1]; however, the axial resolution has been limited to the order of 10 μm due to the dispersion. As an alternative technique, quantum optical coherence tomography (QOCT) has been demonstrated in 19-μm resolution and shows dispersion-tolerance by virtue of the quantum correlation of entangled photon pairs [2].

The study of the interaction between quantum systems and their environment is central to the understanding of a broad range of problems. Important examples include the elusive quantum to classical transition, as illustrated most famously by the Schrödinger cat paradox, and non-equilibrium dynamics, as illustrated by the central spin problem. On the applied side, this understanding is an essential step towards quantum metrology, including the development of quantum noise limited detectors.

Quantum simulators such as systems of ultracold atoms in optical lattices enable one to explore exotic quantum phases of matter and systematically study quantum phase transitions between them. Recently demonstrated photonic systems based on circuit QED (Quantum ElectroDynamics) arrays feature exciting properties that set them apart from these conventional quantum simulators. In particular, a crucial difference is the intrinsic open-system character of photon-based systems.

Large-scale quantum networks will require efficient interfaces between photons and stationary quantum bits. Nitrogen vacancy (NV) centers in diamond are a promising candidate for quantum information processing because they are optically addressable, have spin degrees of freedom with long coherence times, and as solid-state entities, can be integrated into nanophotonic devices.

Probability distributions and quantum states are examples of abstract
"distributions" over information such as bit-strings, in which more
than one bit-string may be a possible outcome. Probability
distributions are vectors of non-negative reals; quantum states are
vectors of complex-valued amplitudes, which may interfere
destructively. To investigate the importance of destructive
interference of "possibilities" independently of quantum mechanics, we
