The quantum laws governing atoms and other tiny objects seem to defy common sense, and information encoded in quantum systems has weird properties that baffle our feeble human minds.
An exciting week-long program offered to students in grades 11 to 12.
The Quantum Cryptography School for Young Students (QCSYS) is an exciting week-long program offered to Canadian students in Grades 11-12. This year the program will run through August 12-16, 2013. The program is run by the Institute for Quantum Computing in conjunction with the University of Waterloo
The CAM Conference is a joint meeting of the Canadian, American and Mexican Physical Societies which is held every second year, cycling between locations in Mexico, the United States, and Canada, with Canada hosting the CAM conference every sixth year.
We provide a quantum algorithm for simulating the
dynamics of sparse Hamiltonians with complexity sublogarithmic in
the inverse error, an exponential improvement over previous methods.
Unlike previous approaches based on product formulas, the query
complexity is independent of the number of qubits acted on, and for
time-varying Hamiltonians, the gate complexity is logarithmic in the
norm of the derivative of the Hamiltonian. Our algorithm is based on
a significantly improved simulation of the continuous- and
In this talk, I will give a summary of my recent research on superconducting nanostructures for quantum detection of electromagnetic radiation. In this regard, electrodynamics of topological excitations in 1D superconducting nanowires and 2D superconducting nanostrips is investigated. Topological excitations in superconducting nanowires and nanostrips lead to crucial deviation from the bulk properties.
We will review several proof of principle applications for graphene based devices performed in our group, including in field sensors, electronics, THz spectroscopy, spintronics, nanofluidics, and even musical instruments. We will then discuss the synthesis mechanism of graphene as well as the synthesis of very large single layered graphene monocrystals with various shapes, ranging from hexagons to fractals, dubbed graphlocons.
The goal of two-party cryptography is to enable Alice and Bob to solve tasks in cooperation even if they do not trust each other. Examples of such tasks include bit commitment, coin flipping and oblivious transfer. Unfortunately, it has been shown that even using quantum communication, none of these tasks can be implemented when the adversary is completely general.
