a center for confirmation in quantum chemistry and last not least our own you see the Derby School of Engineering and the main main-chain Institute without the support this meeting would not impossible but if you're
interested in seeing the the talks from the previous meeting 4 years ago you can now go to the the website it's it's listed here and pretty much all the talks were were recorded with some of them unfortunate not having audio because we have decided to skimp and I did it on the cheap with the fuse the students who were not as proficient as I hope the professional we have in the back there so at this time around we and we went expensive and hopefully will will pay off the you do not want you talk to be recorded several people indicated that they do let me know and will simply that recorded but otherwise all the talks will be recorded and will be made available after the meeting is over there are a couple
of the new features and this time and we decided to have 2 best student paper price talks and those will happen Tuesday morning we had a quite a few submissions and Advisory Board generously helped us in selecting of what we thought worthy of the top 2 talks and so those will be presented on a Tuesday morning in half hour slots it will be 1 1 theory and 1 experiment talk and we also have as in the future a panel discussion on theory vs. experiment in quantum error correction and that will happen on Thursday afternoon the moderator will be marked Bourdieu so 1 of the core organizers of this event and finally and we will have a tour of the D-Wave One Ranier chip which is being installed at Eisai which is or off campus location and marina del rey not from the airport i sent out an e-mail last night asking people to indicate with an interest in taking the torso people the reason this happened was a civil people contacted me ahead of the meeting and asked if if they could go and see the box and that's an interesting box to to look at and you can also look inside there is a very very small chance that we will actually be able to I have it up and running and run some models and simulations were some demos for you and that should be interesting surgeon bushel is 1 of the period these working hard on making that happen and by the way your suggestions for all what to run on the chip are a very welcome as seriously if anybody has anything they they'd like to try out were more than open to log to doing that so say if you want to take a tour there will be a shallow and that leaves regular shuttle Italy's from you see 2 2 eyes I that you could use that to go almost all the way to the airport our if you don't need to go to the airport and you can come back here the shell that will take you back finally some
administrative things we had a a last minute schedule switch so the tutorials and all will go a before Robert Ross North as a lunch is up in the vineyard room in the poster shut the session is to say 2 floors up from here and right up the stairs as you go and the posters need to be set up this evening at at the end of the last session at 6 if you have a poster please go in and set up there and then the poster sessions will actually start tomorrow and last until Thursday and finally if you need any assistance with any administrative issues need to from or la the money or the front desk and it can help you out if you haven't registered yet but they will be there whole morning and probably also later and so any any registration and take up with them OK so I can now I 4 years ago I was a lot smarter than this time because I did not volunteer myself to give a talk and this slide I did and so OK I did not have time to prepare any any serious introductory remarks and so I hope you will not find it really obnoxious of me to I
ask you to listen to a four minute video clip from 4 years ago which will my introductory marks then this this is the advantages of having a recording and actually I I check this out I was hoping that it would be appropriate
and I realized that I was discussing the very same thing I don't think I could say it again and I eloquently of this is so here we go 4 minutes so I thought I'd start with a little bit of a historical background I can't back in the the stone age about 10 15 years ago there was a lot of pessimism on the viability of on computation and the were prominent critics such as Hopcroft Landauer who wrote an influential paper in 1985 with the title is quite mechanics useful and in fact he explained in the introduction that this title was a little sweeping and in really mean to to critique quantum mechanics but in fact it's his target was really computation and this was shortly after the publication structures algorithm so and our made the important observations at that time computation was likely to be the fragile in particular he pointed out and that the computation is likely to suffer from localization of by which he meant something like Anderson localization and that's not an issue that receive a lot of attention in the quite killing literature but then a 2nd point was that the quantum computation might suffer from the following problems additionally small areas he wrote will accumulate and cause a computation to go off track and now this said this was a very insightful critique which of course has to do with with decoherence and went on to say as I make some qualitative statements to this effect conti inspired some as some additional works of for example a paper by by Bologna which was published in the same year in which he acknowledges is aligned hours up I insights into into this issue and Andrew decided to make a calculation to to check with a car computers could actually function in the presence of noise any rights in the abstract it is found that 4 quantum calculations in which the maintenance of coherence over a large number of states is important not only must the coupling the small but the time taken in the quantum calculation must be less than the thermal timescale age Grover K. t so he was able to show by analyzing a model that on computers would would not be able to survive at all and in his conclusions he makes the following statement the above analysis is given a preliminary look at the effects of decoherence require computers it suggests that this problem is going to require some serious thought in order to design systems to avoid a disastrous effects that the loss of of coherence due to the coupling to the environment in Khot so serious thought was was indeed required and fortunately it and take very long and in 1995 that same year appear Shor and then shrewdly followed by hundred scenes of have been published papers which showed for the 1st time the viability of cloud computing in the presence of decoherence and the insight was to use of Quantum error-correcting codes so now shores paper entitled scheme for reducing the coherence and quantum memory pointed out on me reading and from the abstract is shown how to reduce the effects of decoherence for information stored worry assuming that the decoherence process acts independently on each of the bits stored in memory this involves the use of the quantum analog of error-correcting codes so critical insights which was then also and a pointed out by by interesting in is I would say almost companion paper to to shores paper error correcting codes in quantum theory Stephen wrote a natural link is then revealed between this a quantum theory in the linear error correcting codes of classical information theory so Shorenstein the scene for what was to come and what was to come is going to be have talked about a lot of at this conference and so I'm not looking forward greatly to hearing about all the the most recent developments in the subject so let me let me that said I hope these remarks are still pertinent and with that electrical and QC 11 and invite my co-organizer problem to get from some of the the would you like this app this
