I’m at Benasque, Spain for the Quantum Coherence and Decoherence 2010 conference. The participants are people I feel I should have met a long time ago. Also, the center is in a beautiful new building with many areas for discussion, all with blackboards.
This is my first time at Benasque, and the philosophy of the conference is great: this is a place for people to meet and get new collaborations going. The program is informal, but well attended. The talks are decided depending on the group’s interests. Yesterday, it was Discord Day:
- Quantum Discord and Quantum Computation – Animesh Datta gave a fantastic review of the definition of discord, and then of his work on its role as a quantum resource for DQC1 algorithm.
- System-Environment Quantum Discord for General Dynamics – I discussed the very special properties that classical correlations between the system and the environment have. In particular the issues of Complete Positivity, its connection to No-Broadcasting, and to general bounds for decoherence rates.
- Quantum Discord, One Goblin, and Two Demons – Aharon Brodutch presented a picture where quantum discord is related to Szilard Demons, as well as some preliminary result suggesting that you need entanglement in other to process discord for quantum computation.
- Operational Interpretation of Quantum Discord – Leandro Aolita provided a much-looked-for operational interpretation for quantum discord. In particular, he showed how it is related to quantum state merging.
If you want to succeed in the world, you don’t have to be much cleverer than other people. You just have to be one day earlier.
