IQC Colloquium Featuring Dr. Stephanie Simmons - Photonic

The future global quantum internet will require high-performance matter-photon interfaces. The highly demanding technological requirements indicate that the matter-photon interfaces currently under study all have potentially unworkable drawbacks, and there is a global race underway to identify the best possible new alternative. For overwhelming commercial and quantum reasons, silicon is the best possible host for such an interface. Silicon is not only the most developed integrated photonics and electronics platform by far, isotopically purified silicon-28 has also set records for quantum lifetimes at both cryogenic and room temperatures ...

IQC Colloquium Featuring Anupam Mazumdar, University of Groningen

We are led to create a massive and large spatial quantum superposition to probe the quantum nature of gravity in a laboratory. In particular, to witness the quantum entanglement mediated via the quantum nature of gravity, we will need to prepare a pure quantum state of mass 10^{-15} -10^{-14}Kg with a spatial quantum superposition of 10-100 microns and a coherence time of nearly 1-2 seconds. ...

IQC Math CS Seminar - featuring Mario Szegedy, Rutgers University

Motivated by quantum network applications over classical channels, we initiate the study of n-party resource states from which LOCC protocols can create EPR-pairs between any k disjoint pairs of parties. ...

Seminar Presentation by Richard Germond, Queen's University

A number of astrophysical and cosmological observations suggest that roughly 85% of the matter in the Universe is composed of dark matter, presumed to be a particle outside the standard model of particle physics. Direct detection experiments look for signatures of a dark matter particle scattering with a sensitive detector; of the different technologies used for this, cryogenic detectors are well-suited for detecting low-mass dark matter due to their low energy thresholds.

Introduction to Majorana Topological Qubits

Abstract: This presentation will introduce some of the experimental approaches to building topological qubits and the theories supporting current research. Beginning from the early toy models that first proposed the formation of Majorana bound states, I aim to convey an understanding of why topological qubits are so resistant to decoherence. I will introduce the “ingredients” necessary to build a Majorana device and some of the challenges involved. Finally, I will discuss the field's current state and what might be next on the journey to making topological quantum computing a reality. Neither an understanding of topology nor quantum algorithms are necessary to enjoy this talk!

Categories of Kirchoff Relations

Abstract: I will be talking about the connections between electrical circuits and stabilizer qudit quantum circuits with an eye towards applications to qudit quantum error correction. More formally I will be defining a category dubbed Kirchhoff relations and characterize the maps in this category using parity check matrices. I will then go on to give a universal set of generators for this category and interpret these generators in-terms of electrical elements.
