Toronto Quantum Computing Meetup, Next Event Featuring 3 Local Stars

Filed under: Uncategorized — rrtucci @ 4:39 pm

The Toronto Quantum Computing Meetup is the largest meetup in the world dedicated to quantum computing, so we claim the title of Quantum Meetup Supremacy, at least for now. (currently we have 1101 Supremos as members. The second biggest club is in London with 951 Brexiters members. The Quitters Brexiters have been growing fast lately. We see what you are doing: trying to sneak up on us and steal our crown. You guys are pathetic! It will never happen! Never! Grow up, you bunch of Peter Paners! )

We cordially invite you to our next meeting on Friday, April 20, 2018. The Event will feature 3 local stars, “Tres Amigos”, speaking about 3 different quantum computing related topics:

  1. Colin Lupton (from Black Brane Systems Inc.)
  2. Turner Silverthorne (from Zero Gravity Labs, part of Loyalty One)
  3. Hassan Bhatti (from CDL- Creative Destruction Lab, part of U of Toronto’s Rotman School of Management)

There will be FREE PIZZA, courtesy of ZGL

We are eternally grateful to ZGL (Zero Gravity Lab) for providing the venue for the event. ZGL is the super cool research lab of Loyalty One.

Loyalty One is one of the largest loyalty marketers in Canada.

IBM announces partnership with 8 startups and Zapata announces $5.4M seed investment

Filed under: Uncategorized — rrtucci @ 3:22 am

Check out this IBM Press Release. It announces that the following 8 startups will be joining the “IBM Q Network”

  1. Zapata (U of Toronto, Aspuru-Guzik)
  2. Strangeworks (Austin TX, Whurley)
  3. QXbranch (Australia, M. Brett)
  4. Quantum Benchmark (Waterloo Canada, Lazaridis)
  5. QCWare (Ames-NASA)
  6. Q-CTRL (Univ. of Sidney, Biercuk)
  7. Cambridge Quantum Computing (London, Ilyas Khan)
  8. 1QBit (Vancouver)

It seems that the main thing these startups are getting is free access, which is not granted to everyone, to the 50 qubit IBM quantum computer. Not exactly like winning the lottery though. I suspect that in a few weeks, Google will grant everyone free access to their 72 qubit quantum computer.

The first company to be mentioned is Zapata, which starts with the letter Z. huh?? Inverse alphabetical order? You’ve got to be kidding me. Isn’t Zapata soon going to be one of IBM’s main competitors in the quantum chemistry arena? Isn’t IBM betting their qc farm on quantum chemistry? I hope, for IBM’s sake, that the master mind at IBM who conceived this program knows what he is doing.

Zapata has been much in the news lately.

Aspuru-Guzik, prof at Harvard for almost a decade and famous for his work using quantum computers to do chemistry, is moving to the U of Toronto in July. (I suspect that Matthias Troyer, another quantum chemistry eminence, will be offered and will accept the position at Harvud being vacated by Aspuru. If that happens, this will totally, completely deplete Microsoft’s quantum chemistry brain trust. He he).

Aspuru started Zapata a few months ago. Yesterday, Zapata announced that it obtained $5.4M in seed funding!!

All this Zapata news is very good news for us, artiste-qb.net. Our business plan has nothing to do with quantum chemistry, so there is very little overlap between Zapata and us. Zapata will attract qc talent to Toronto, artiste-qb.net’s home town. Such a high valuation for Zapata makes Artiste a real bargain.

3 of the 8 companies in the above list got their original funding less than 5 years ago by promising to investors that they would write software that would run on Dwave’s annealer quantum computer. But now they claim they were IBM’s best buddies and gate model experts all along. Gate model and annealer softwares look nothing alike. Judases!

All this IBM press coverage must have Microsoft stewing with envy. MS won’t have an anyon quantum computer for at least 5 years, if ever. But MS could easily compete with Google and IBM in the transmon quantum computer arena by buying Rigetti (or some similar, alternative startup, like Yale QC). The price of Rigetti is pocket change to MS. I’m sure such a sale is being actively discussed behind closed doors. After all, very few Silicon Valley startups ever reach IPO; instead, they either go bankrupt or are bought out by one of the giant Valley companies.

PyMC and Edward/TensorFlow Merging?

Filed under: Uncategorized — rrtucci @ 9:09 pm

News bulletin: Edward is now officially a part of TensorFlow and PyMC is probably going to merge with Edward.

The python software library Edward enhances TensorFlow so that it can harness both Artificial Neural Nets and Bayesian Networks. The main architect of Edward, Dustin Tran, wrote its initial versions as part of his PhD Thesis at Columbia Univ. (Columbia is the home of the illustrious Andrew Gelman, one of the fathers of hierarchical models, which are a special case of Bayesian networks). Dustin now works at Google as part of a team merging Edward with TensorFlow.

One of the near term goals of artiste-qb.net is to produce a quantum generalization of Edward. This would not run on a quantum computer but would simulate on a distributed classical computer possible experiments that could in the future be conducted on a qc.

I highly recommend the following two Discourses for Edward and PyMC:

It looks like the python software libs PyMC3 and Edward may soon merge:


This is very good news, in my opinion, because I am in love with both programs. It’s interesting to note that the current Numpy is also the result of the fortuitous marriage of two separate complementary software libs.

One can now call PyMC3 and Edward from Quantum Fog, although not very smoothly yet. See here.

The Wicked Witch of the West, Krysta Svore

Filed under: Uncategorized — rrtucci @ 10:29 pm

2 years ago, I pointed out that Krysta Svore often behaves unethically.



What devious misdeeds has she been up to lately? Well, as of today, April 3, 2018, she has:

  • a whopping 24 software patent applications (14 of those are on quantum computing). See USPTO search results here Check it out. Pretty soon, you won’t be able to do some pretty trivial operations in quantum AI without paying Microsoft.
  • a whopping 15 granted software patents (8 of those are on quantum computing). See USPTO search results here.

In a previous blog post, I compared in detail artiste-qb.net’s quantum computing language Qubiter to Microsoft’s quantum computing language Q#. Q# is a Rube Goldberg machine language that doesn’t even look like what everyone else calls quantum computing. It looks very different and is much more convoluted than its major competitors (IBM qasm, Rigetti PyQuil, Google’s ProjectQ, and the best of its class, Qubiter). Why would anyone want to learn another crappy Microsoft language, when, instead, they can use Python, like all the competitors just mentioned are doing?

So why does Q# suck so badly. Is this just a consequence of Microsoft’s penchant to monopolize markets and “bind for life” its customers to its products, or is there an aggravating factor. Yes there is an aggravating factor. It’s that one of the main architects and promoters of Q# is the Wicked Witch of the West, Krysta Svore.

In a scary nightmare that I keep having, Krysta yells the following curse to all qc fans:

“From the pits of Microsoft Hell, I curse thee, may you, and your children, and your children’s children, and their little dogs too, be forced to use Q# for the rest of their careers. ha, ha, ha, I made it extra convoluted to enjoy your pain.”

I predict that Q# will end up being as popular as the Zune. Will Microsoft rightly blame Krysta for the abysmal failure of this product, or will they blame Dave Wecker instead? Whoever is blamed will probably end up in Microsoft-Siberia, vanished from quantum computing land, bug testing new features for Microsoft-Office.
