Quantum computers can solve a linear algebra problem faster than classical computers, according to a new study published in Science. The finding proves that constant-depth quantum circuits are more powerful than their classical counterparts, and provides a new sense of how quantum technology will be a key to more powerful computing.

A step further for secure quantum communication and scalable quantum computing
A team of researchers at the Institute for Quantum Computing (IQC) generated three-photon entanglement on a superconducting chip using a new, scalable technique.
The experiment, published in Physical Review Applied, could lead to advances in quantum communication protocols like secret sharing and in quantum computing power.

PhD Seminar: Olivia Di Matteo
Quantum random-access memories (qRAM) are required by numerous quantum algorithms. In many cases, qRAM queries are the limiting factor in the implementation of these algorithms. In the limit of a large number of queries, there will be a massive resource overhead, as in this regime it is not possible to bypass the need for active error correction. In this talk, I will present our work towards quantifying this overhead. We will explore a variety of different qRAM circuits designed to query classical bits in superposition.

Crafting high-dimensional tools for photonic quantum networks with tailored nonlinear optics
John Donohue, Institute for Quantum Computing
The time-frequency degree of freedom of light offers an intrinsically high-dimensional encoding space which is naturally compatible with waveguide devices and fiber infrastructure. However, coherent manipulation and measurement the information-carrying modes presents a challenge due to the sub-picosecond timescales inherent to downconversion-based photon sources. In this talk, I will discuss methods based on ultrafast pulse shaping and sum-frequency generation to address these temporal modes.

Abstract: The patent system provides a monopoly in return for disclosure of new technology. The disclosures (patent applications) are published and classified by technology to provide an extensive global resource available on line.
