A Brief Overview of Quantum Communications
01 Sep 2022 | | Contributor(s):: Yisheng Lei
In this seminar, I will explain the working principles of quantum key distribution (BB84 & Ekert 91 protocols), quantum repeater (entanglement swapping, entanglement purification & quantum memory), Bell state measurement, quantum teleportation and also its recent experimental progresses.
Exploring Synthetic Quantum Materials in Superconducting Circuits
30 Apr 2020 |
Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. I will show our recent experiments to apply this toolbox to the exploration of strongly correlated quantum materials made...
Entanglement, Discord and Other Quantum Correlations
15 Oct 2019 | | Contributor(s):: A. Ravi. P. Rau
We will discuss states and operators of two (or more) qubits, and higher dimensional "qudits," from the symmetry groups and algebras pertaining to them. The study of the time evolution of such systems can gain much from the insights and techniques provided by such considerations,...

Frequency Bin Quantum Photonics
11 Jul 2019 | | Contributor(s):: Andrew M Weiner
In this talk I discuss recent advances in manipulation and measurement of quantum states encoded and entangled in the photonic frequency degree of freedom or hyperentangled in time and frequency degrees of freedom. Although the perspective is primarily experimental, I will also attempt to...
Quantum Optics on a Nonlinear Chip
08 May 2018 | | Contributor(s):: Alexander Solntsev
Bringing the concepts of quantum entanglement and optical nonlinearity together, and integrating them on a chip, opens a way to efficient generation of entangled photons and entanglement.
Toward Quantum Enhanced Plasmonic Sensors
14 Dec 2016 | | Contributor(s):: Alberto Marino
In this talk I will describe our work towards this goal based on the interface between quantum states of light, known as twin beams, and plasmonic sensors.
Bringing Quantum Mechanics to Life: From Schrödinger's Cat to Schrödinger's Microbe
01 Nov 2016 | | Contributor(s):: Tongcang Li
In this talk, I will first give a brief introduction to basic concepts in quantum mechanics and the Schrödinger's cat thought experiment. I will then review developments in creating quantum superposition and entangled states and the realization of quantum teleportation. Non-trivial quantum...
07 Feb 2012 | | Contributor(s):: Ross Hoehn
Ross Hoehn gives a brief introduction to the basic concepts used in the quantum information field. He conveys linear superpositions and entanglements through penguin coordinates and marital disputes and follows up with the presentation of an entertaining game which both teaches and emphasizes...
Tangling with Entanglement: Polar Molecules as Qubits
11 May 2011 | | Contributor(s):: Dudley R. Herschbach
For arrays of polar molecules, entanglement is supplied by dipole-dipole interaction. Previous studies of prospects for computing with diatomic polar molecules had specified experimental conditions deemed suitable and accessible. This talk reports the first calculations of entanglement pertaining...
ECE 659 Lecture 38.0: Correlations and Entanglement
04 May 2009 | | Contributor(s):: Supriyo Datta
This lecture is from the series of lecturesNanoelectronics and the Meaning of Resistance.
An Introduction to Quantum Computing
out of 5 stars
12 Sep 2008 | | Contributor(s):: Edward Gerjuoy
Quantum mechanics, as formulated more than 80 years ago by Schrodinger, Heisenberg, Dirac and other greats, is a wholly sufficient foundation for its modern interrelated subfields of quantum computation (qc) and quantum information (qi), which generally are lumped together into a single subfield...
Nanoelectronics and the meaning of resistance: Course Handout and Exercises
02 Sep 2008 | | Contributor(s):: Supriyo Datta
Handout with reference list, MATLAB scripts and exercise problems.
Lecture 5A: Correlations and Entanglement
20 Aug 2008 | | Contributor(s):: Supriyo Datta
Objective: To relate the one-electron picture used throughout these lectures to the more general but less tractable many-particle picture that underlies it. We introduce this new viewpoint using the example of Coulomb blockaded electronic devices that are difficult to model within the picture...
