Hybrid quantum circuit with a superconducting qubit
coupled to a spin ensemble
Denis Vion
CEA-Saclay, Gif-sur-Yvette Cedex (France)
We report the experimental realization of a hybrid quantum circuit combining a superconducting qubit and an ensemble of electronic spins. The qubit, of the transmon type, is coherently coupled to the spin ensemble consisting of nitrogen-vacancy (NV) centers in a diamond crystal via a frequency-tunable superconducting resonator acting as a quantum bus [1,2]. Using this circuit, we prepare arbitrary superpositions of the qubit states that we store into collective excitations of the spin ensemble and retrieve back later on into the qubit [3] with a fidelity of about 10%. These results constitute a proof of concept of spin-ensemble based quantum memory for superconducting qubits.

Student conference in Waterloo (Waterloo!) in June.
-------- Original Message --------
Subject: student conference on quantum information at IQC
Date: Fri, 16 Mar 2012 15:11:32 -0400
From: Stacey Jeffery <smjeffery(a)gmail.com>
To: delrio(a)phys.ethz.ch
Hi Lidia,
I just wanted to let you know we're having a student conference on
quantum information at IQC this June 18 - 22. More information and
registration can be found at http://aqua2012.uwaterloo.ca/
There's some travel support available, if you apply before April 15.
Early registration deadline is April 25.
I hope you can make it, and also encourage any other graduate students
in the field that you know to consider attending. It's a great
opportunity to meet other students and present your research, and also
should be a lot of fun.
Cheers,
Stacey

Why physicists should care about information theory
Renato Renner
Institute for Theoretical Physics, ETH Zurich
According to a quote by the physicist Rolf Landauer, "information is physical". By this, he meant that information could not exist without a physical information carrier (such as the ink on a piece of paper). Information may therefore be studied from a "physical perspective". The development of Quantum Information Theory, which accounts for the fact that any physical information carrier ultimately obeys the laws of quantum mechanics, is one of the consequences of this approach. Very recently, however, researchers have started to take a converse approach, studying physics from an "information-theoretic perspective". This leads to interesting novel insights, a selection of which I will present in this talk.
