# 054 – Quantum Computing

Rate/Vote |

In this Episode, we talk about quantum computing. Our guest is Martin Laforest from the Institute for Quantum Computing at the University of Waterloo, Canada. We start with some physics basics, and then cover topics ranging from how quantum computing works, which different models of quantum computing are explored, current and future uses of the approach as well as the current state of the art. This is one of the more propellerhead-oriented episodes, so make sure you listen carefully :-)

Great Show. Really interesting topic.

As much as I enjoy aviation related episodes I do prefer this kind of episodes.

Also liked that you finally dropped the music.

hey, thanks for the quick feedback :-)

Great show, as usual. MORE ENGLISH EPISODES, PLEASE! I’m a stupid, monolingual American!

I am working on it :-)

Markus

I have to agree with an earlier comment that the shows are interesting, but seeings as I can only speak and read English, we need more English shows.

Thanks, Ron

yeah, yeah, yeah :-) I will do more english stuff. Problem is this: I like to go and visit people and stuff. And for reasons of travel expenses and time, this is mostly in Germany. Hence the many episodes. Send me money, and I’ll go wherever you want me to go :-)

Hi Markus,

Just back from a long walk. Listened to your podcast on quantum computing. There were interesting concepts. Very complicated. Had to take some notes.

Martin said clearly it’s early days for quantum computing. Seems we are still at the embryonic stage. Not even at the ENIAC valve and pre-memory accumulator level. My gut-feeling is that quantum computing will use fuzzy logic rather than digital. The statistical nature and mathematical models seem to be heading that way. If it turns out to be digital then I can see it being on a higher level with the microcode of the firmware using fuzzy logic set of operations.

When Martin talked about possible breakthroughs using Shor’s algorithm and molecular modelling to achieve superconductivity at room temperatures I can see the effort being worthwhile. No doubt, when quantum computing gets off the ground, so to speak, it will be used to accelerate its own development. Look at flight.

I am a little concerned about Martin’s enthusiasm about sensing. A quantum computer that can sense has the potential to develop self-awareness and consciousness; and I don’t mean just passing a Turing test. Look at what happened to HAL in 2001; not to mention Terminator.

As far as music is concerned, I found the interludes refreshing. I’ll go along with the majority though.

Keep churning out the interesting talks.

Regards,

Geoffrey

PS: Any chance of doing a talk on supersymmetry?

Sure, supersymmetry is on the list, but not anytime soon.

Cheers,

Markus

Thanks for the podcast! As a theoretically inclined EE student I really like episodes like this one and the two you did on wolphram alpha. Keep up the good work :-)
