A New Approach to Entanglement in Large Quantum Systems
Yuri M. Suhov, University of Cambridge, England, T. D. Voice
Tue Jan 28, Wed Jan 29, 03:30-05:00pm, NW14-1112
No enrollment limit, no advance sign up
Participants requested to attend all sessions (non-series)
Prereq: Introductory Quantum Mechanics, Second Year Calculus
We propose a new approach to the entanglement in large quantum systems. Basically, the emphasis is shifted from attempts to find `best entangled' vectors for moderately many qubits to attempts to find complete orthogonal families of `moderately entangled' vectors for many (eventually for infinitely many) qubits. A review of the existing literature will be given and comparisons will be made of different measures of entanglement and their applicability.

Applications of Geometric Algebra to Quantum Physics
Dr. Chris Doran, Astrophysics Group, Physics Dept., Cambridge Univ.
Mon Jan 27, 02-05:00pm, NW14-1112
No enrollment limit, no advance sign up
Participants requested to attend all sessions (non-series)
This is an overview of the quantum physics part of a course given at Cambridge University, called "Physical Applications of Geometric Algebra". After a brief introduction to geometric algebra, we will study its role in the representations of single-particle spinors, before constructing multiparticle states and density operators. Applications to quantum information will be highlighted. Some mention will also be made of extending the main concepts to the relativistic setting, which raises interesting theoretical questions.

Fostering Innovation: Bridging Academia and Industry at MIT
Jason Shumaker, Joost Bonsen
Enrollment limited: first come, first served
Limited to 30 participants.
Participants welcome at individual sessions (series)
Prereq: none
Why does MIT value a creative culture and how can one tap into the available resources and relationships to be innovatively successful at the Institute? The Cambridge-MIT Institute attempts to answer these questions by looking at new technologies and their influence at and around MIT; the role of mentoring as demonstrated by the Venture Mentoring Service; and the entrepreneurial spirit of MIT faculty, with a specific focus on American Superconductor. Dates for specific events listed below. Limited enrollment for tours and site visits.

Quantum Maps and Density Operators: An Introduction to Beyond the Unitary
Daniel Kuan Li Oi University of Cambridge, England
Mon Jan 27, Wed Jan 29, 09-10:30am, NW14-1112
No enrollment limit, no advance sign up
Participants requested to attend all sessions (non-series)
Prereq: Introductory Quantum Mechanics, Two Years of Calculus
In this preparatory course, the concepts of the density operator and mixed states will be introduced. Mixed states naturally arise from non-unitary evolution of initially pure states. These evolutions can be characterised by (completely) positive maps or channels acting on the state space of density operators. The physical significance of complete positivity will be discussed. Two ways of describing completely positive maps are the Kraus, and the Unitary / Ancilla representations. The positive maps on the qubit will be used as an illustrative example.

Topics in Quantum Cryptography
Adrian Kent, University of Cambridge, England
Tue Jan 28, Wed Jan 29, 01-03:30pm, NW14-1112
No enrollment limit, no advance sign up
Participants requested to attend all sessions (non-series)
Prereq: Introductory Quantum Mechanics, Second Year Calculus
These lectures look at the current state of the art in quantum cryptography applied to tasks which, unlike key distribution, are carried out between mistrustful parties. I focus in particular on known protocols, security proofs, and no-go theorems for bit commitment, coin tossing, and related tasks, and try to draw some general morals about the scope for research in quantum cryptography.
