The school is designed for researchers in mathematics, physics or computer science who are interested in learning about quantum information.
Semiconductor quantum dots provide a versatile and potentially scalable mechanism for manipulating quantum information encoded in discrete orbital and spin degrees of freedom. I will review the state-of-the-art in current developments in this field (leading to fast control on a scale of 200 picoseconds and very long memory times in excess of 200 microseconds).

Quantum Money from Hidden Subspaces
Yingdan Wang, McGill
It’s often useful to have a private conversation within a public world. What role can quantum cryptography play in keeping conversations private? Sometimes described as providing “unconditional security guaranteed by the laws of quantum physics,” its security implications are both tantalizing and surprisingly elusive. This talk introduces quantum cryptography and describes the speaker’s experience creating several types of quantum cryptography equipment, within the broader context of mainstream cryptography and secure communications.
Biography
Evidence is presented for the finite wave vector crossing of the two lowest one-dimensional spin-split subbands in quantum point contacts fabricated from two-dimensional hole gases with strong spin-orbit interaction. This phenomenon offers an elegant explanation for the anomalous sign of the spin polarization filtered by a point contact, as observed in magnetic focusing experiments. Anticrossing is introduced by a magnetic field parallel to the channel or an asymmetric potential transverse to it.
