Traveling wave packets of light prepared with a definite number of photons, known as multimode Fock states, are well-suited for the role of "flying qubits" to relay information in a quantum computing device. In both the optical and microwave domain, propagating single-photon fields are routinely produced and manipulated, with ongoing progress toward higher photon numbers.

Pushing the boundaries of research and innovation

The 5th Annual Canada Excellence Research Chairs (CERC) meeting brings together CERCs from across Canada to share key developments and the latest discoveries in their respective research programs.

Attend the free conference to meet with world-renowned researchers and get an overview of Canada's latest scientific achievements. Participants may attend plenary lectures, research seminars and interact with the CERC holders, researchers and students during the poster session.

Fault tolerant quantum computing is possible by employing quantum error correction techniques. In this talk I will describe an implementation of a true quantum code using 4 lithographically defined superconducting qubits in a square lattice capable of measuring both types of possible quantum errors occurring on a single qubit. The experiment requires highly coherent qubits, high quality quantum operations implementing the detecting circuit, and a high quality independent qubit measurement set-up.

While IBM Zurich's millipede project of data storage did not
have the success anticipated it would, a new technology for nano
lithography was born. Since 2009, IBM Zurich has been refining their

Fundamental to quantum optics is the study of the distribution of photons in modes of an electromagnetic field. Until now, direct photon number measurements on nonclassical states occupying a single mode have been limited to the few-photon regime (typically no more than 5). I will present results from direct measurements of nonclassical states containing up to 50 (fifty) photons, at telecom wavelengths and with total raw efficiencies well above 60%.

The debate on wave vs particle nature of light goes back to the days of Huygens and Newton. When used to model properties of quantum system these concepts lose their objective meaning and simply become the two aspects of wave-particle duality. Duality played a central role in Bohr—Einstein debates and prompted Bohr to formulate the complementarity principle. Complementarity leaves open the possibility that by adapting to the specific experimental sit-up a quantum system always behaves definitely either as a particle or as a wave.

The focus of this talk will be a general introduction to Nuclear Magnetic Resonance (NMR) detection schemes that are based on the use of Superconducting Quantum Interference Devices (SQUIDs) as highly sensitive magnetometers. I will begin by providing an overview of the relevant concepts and principles behind SQUID-detected NMR. In the main part of my talk I will be presenting our experimental results and achievements in the field of ultralow field SQUID NMR spectroscopy and Magnetic Resonance Imaging (MRI).

In a double slit interference experiment, the wave function at the screen with both slits open is not exactly equal to the sum of the wave functions with the slits individually open one at a time. The three scenarios represent three different boundary conditions and as such, the superposition principle should not be applicable. However, most well-known text books in quantum mechanics implicitly and/or explicitly use this assumption that is only approximately true.
