WELCOME

The Structural Quantum Optics (SQO) group at the University of Ottawa is a
pioneering research group, globally recognized in generating, detecting, and
manipulating the structured quantum waves, e.g., photons and electrons beam, and
their applications in modern science and technology, such as quantum
communication, sensing and materials science. Founded in 2014, the SQO group is
an expert in designing and developing instruments employing the most extreme
available quantum technologies to probe very fundamental and applicable aspects
of materials. As a member of the Max Planck-University of Ottawa Centre for
Extreme and Quantum Photonics, we extensively collaborate with researchers from
the Max Planck Institute for the Science of Light in Erlangen-Germany, and have
access to their state-of-the-art facilities and expertise. We are a founding
member of the Joint Centre for Extreme Photonics (JCEP), a joint undertaking
between the National Research Council (NRC) and the University of Ottawa. SQO
members have access to and closely collaborate with scientists from the NRC. We
always welcome collaborations, and partnerships. The best way to reach out to us
is via email at SQO@uottawa.ca

NONDESTRUCTIVE MEASUREMENT ON ELECTRON WAVEPACKETS

Free electrons with a helical phase front, referred to as “twisted” electrons,
possess an orbital angular momentum (OAM) and, hence, a quantized magnetic
dipole moment along their propagation direction. This intrinsic magnetic moment
can be used to probe material properties. 




RECONSTRUCTING THE TOPOLOGY OF OPTICAL POLARIZATION KNOTS

Free electrons with a helical phase front, referred to as “twisted” electrons,
possess an orbital angular momentum (OAM) and, hence, a quantized magnetic
dipole moment along their propagation direction. This intrinsic magnetic moment
can be used to probe material properties.
