One of the tasks that quantum computing promises is algorithmic speedups over classical computing for certain types of problems – one of which is quantum searching. To achieve this, it’s important to build a robust quantum memory, more specifically, a memory that can store information which can be addressed quantum mechanically.
University of Waterloo researchers performed a lab demonstration proving the feasibility of Quantum Key Distribution over a satellite uplink.
In an emulated environment for performing QKD, a team of researchers analyzed the impact of the optical loss that occurs between the photon source and the satellite receiver. They successfully generated a secure key using algorithms tailored for a satellite receiver, an important step towards extending the distance of ultra-secure communications.
Researchers in Canada, the United States and Europe led by the National Institute of Standards and Technology in Boulder, Colorado and Institute for Quantum Computing alumnus Krister Shalm have ruled out classical theories of correlation with remarkably high precision. A group including Institute for Quantum Computing members Evan Meyer-Scott, Yanbao Zhang, Thomas Jennewein, and alumnus Deny Hamel built and performed an experiment that shows the world is not governed by local realism.
A team led by Professor Thomas Jennewein at the University of Waterloo’s Institute for Quantum Computing (IQC) has successfully completed the development of the crucial Acquisition, Pointing and Tracking (APT) fine pointing system for a future Quantum Key Distributio
The Institute for Quantum Computing acknowledges that we are on the traditional territory of the Neutral, Anishinaabeg, and Haudenosaunee peoples. The University of Waterloo is situated on the Haldimand Tract, the land promised to the Six Nations that includes six miles on each side of the Grand River. Our actions toward reconciliation take place through our research, teaching, learning, and community events, with guidance from the University’s Indigenous Initiatives Office.
