Today on Christmas day 2018 (or a day after, but close), our internal Slack channel brings us good tidings from the East. Our man in Shenzhen, Artiste-qb.net cofounder Dr. Tao Yin, informs us that Bayesforge.com is now available on the Tencent cloud.


Previously, it was only available on the Amazon cloud (AWS), but our Chinese users complained that the Amazon cloud service in China is too slow.

To all Quantum Computing Startups Partnering With Microsoft, have a Merry Microsoft Christmas

Filed under: Uncategorized — rrtucci @ 6:24 pm

Microsoft has recently been touting its partnership with several qc startups.

Copycats. IBM and Rigetti have been touting bigger lists than that of qc startups for over a year. And IBM and Rigetti have actual qc hardware to offer their partners, whereas Microsoft is hardware-less.

Microsoft has been compared to Star War’s Evil Empire since the first Star Wars movie came out in 1977. And the comparison has stuck until today because it fits so well.

As a member of a qc startup (artiste-qb.net) which is not in the above partners list, I have to wonder, could a partnership with Microsoft be a trap?

As a Microsoft partner, you qc startups get no money from Microsoft. What you do get is that MS now expects you to write software for them, for free, in their opaque language Q# (aka Krysta’s Curse), a qc language that is as popular as the Zune. Q# is a Rube Goldberg contraption that will soon come crashing down

To all qc startups partnering with Microsoft, here is what happens if your faith in Q# waivers

And if you have any good ideas of your own, or an employee that is key to your company, will Microsoft appropriate them and cast you aside? Did MS get to be a giant monopoly by nurturing young competitors? “Do you still believe in Santa?, because, at seven, it’s marginal.” (Quote from the 45th president of the USA, Donald J. Dump)

Here is what it must feel like to be an MS partner.

Galactic Battle now going on in Quantum Space Between our Google OverLords and Dubai Inc.

Filed under: Uncategorized — rrtucci @ 6:41 pm

Recently, the company IonQ announced that they have already built and are operating an ion trap quantum computer with 160 FULLY CONNECTED high fidelity qubits. The device’s 1-qubit and 2-qubit gate fidelities are reported to be 99.97% and 99%, resp. See IonQ’s press release, and Gizmodo article.

The thing that may have escaped the attention of casual readers because it is rarely emphasized, although it isn’t hidden (see Wikipedia article on IonQ), is that IonQ’s main investor is GV=Google Ventures, which is a wholly owned subsidiary of Alphabet, the umbrella company that owns all Googlish subsidiaries. A tree diagram of all Alphabet companies is quite impressive (and scary). In other words, IonQ is really just a branch of Google in disguise. So Google is betting big on both an ion trap and a Josephson junction quantum computer. Don’t know about you, but in the last five years, I have grown highly dependent on Android (a Google product) with its mostly proprietary Google apps, Google search, Chrome, Gmail, Google Maps, Google Drive, YouTube, Google News, TensorFlow, … I seem to find Google under every rock these days. And they are now aiming to control what I call the ‘Holy Trinity’: cloud, AI and quantum computing.

Meanwhile, in another sector of quantum space, Rigetti computing is getting ready to attack our Google Over Lords. Rigetti started in 2014. At that time, it seemed to me to be a joke company started by a $2.5M seed investment from the controversial billionaire Tim Draper. But since then, Rigetti has been funded to the tune of $120M, according to Crunchbase. So where did this flash flood of money come from? According to Wikipedia, the main Rigetti investors are Vy Capital (> $40M) and Andreesen Horovitz (> $24M). Vy Capital is based in Dubai, United Arab Emirates. It is reasonable to assume that Vy Capital’s extravagant spending habits and penchant for high risk is fueled by super rich Arab investors. So Vy Capital, aka Dubai Inc., is the main investor of Rigetti.

So you see, there is indeed a galactic battle going on between 2 Google quantum clones and Dubai Inc. But it gets better:

Like I said before, at first I considered Rigetti to be somewhat of a joke, but now that so much money has been invested in them, it is much harder for me to be dismissive about them. Once Dubai Inc invested the $40M in Rigetti, many smaller “lemming” VC’s followed, because they realize that now Rigetti has become too big to fail as an investment. And Rigetti/Dubai Inc have promised some very attractive sweeteners this year: A 128 qubit qc by next year, a cloud service for hybrid quantum-classical AI, and a $1M prize for the first proof of a quantum advantage. My suspicion is that Dubai Inc. is prepping up Rigetti, making it attractive, so that Microsoft buys it for a few billion dollars. Microsoft might fall for it, because they won’t have a topological qc for many years, if ever, and their obscure quantum language q# is flopping badly, as I predicted. This is actually a common practice in Silicon Valley. They like to jack up the valuation of a startup, and then, instead of doing an IPO, sell it to one of the giant monopolies like Microsoft, Apple, Facebook, Google, Amazon (MAFGA, a portmanteau of MAFIA and MAGA)

Scotty: “Captain, the quantum entanglement wormhole tunnel that you requested is now operational”

Filed under: Uncategorized — rrtucci @ 9:13 pm

Many prestigious physicists believe that the phenomenon of quantum entanglement is at the very heart of quantum computing and quantum information theory. For example, John Preskill of Caltech uses the word entanglement in every title of every talk and paper he ever writes, or so it seems. Lately, other very famous particle physicists, for instance, Leonard Susskind and Ed Witten, have also begun to sing the praises of quantum entanglement. And it’s not only old timers that babble about it. It seems almost everyone does, young and old, knowledgeable and clueless.

If you Google “quantum entanglement”, and look at the images, you will find a plethora of attempts to illustrate q entanglement graphically. Some illustrations are very whimsical and cute, some are very wrong too, in my opinion. But I won’t be judgemental. Visual analogies are an important part of the fun of doing physics. We start with analogies that are a bit off, but, hopefully, as time goes on, we refine them. When I was a kid, I used to like to picture an alpha particle as a daisy with 4 petals, 2 proton ones and two neutron ones. Hey, not very sophisticated, but at least it allowed me to remember a few basic facts about the Helium nucleus. This morning, I got inspired to try my own hand at picturing quantum entanglement. Here is the doodle I arrived at:

BRIEF EXPLANATION OF IMAGE, only for the theoretically inclined: Starship Ada and Starship Bayes are in separate universes, pictured here as (half) diamond shaped areas called Penrose diagrams. A and B are both adjacent to a black hole which is also portrayed as a Penrose diagram, except that the space and time coordinates are swapped. The two walls of the black hole’s (half) diamond are its event horizon and the dashed line labelled singularity is all the times in the life of the center of the black hole. The two starships are exchanging “entanglement signals” across the event horizon of the black hole. A wormhole is normally defined as a tunnel that connects two Penrose diagrams that overlap at a single corner vertex. The wormhole occupies the single common vertex of the two universes. If you fold the above figure about its middle vertical axis, then the Penrose diagrams of Ada and Bayes sit on top of each other, and are identified as the same universe. Also, the original single black hole becomes two black holes with a wormhole connecting the bottom black hole to the top one. Now you can envision Ada and Bayes as existing in the same universe, but one Starship is close to the top black hole and the other Starship to the bottom one. This is all standard black hole physics. People actually believe these stoner speculations.

To paraphrase Mark Twain: “Everybody talks about q entanglement, but nobody does anything about it”. In particular, for me, a programmer with a Ph.D. in physics, I would like a nice software library for calculating various quantities related to quantum entanglement. Just calculations of down to earth, widely accepted theory. Nothing fringy. I looked around for such a library and found none that I liked so I wrote my own. My software library “Q Entanglement Lab” is now finished and it works like a charm. I suspect it could become some of the most influential work I’ve ever done. I had to invent several new, fairly clever if I may say so, algorithms for calculating entanglement. I am very pleased with how well they work. Of course, at first, they didn’t work at all, so I had to sweat bullets to refine and debug them until they did work.

I still haven’t decided when or how to release “Q Entanglement Lab”. I want it to be open source eventually, but first, I will seek to patent it in China, with the assistance of Dr. Tao Yin. Tao is a cofounder of our company artiste-qb.net, and he runs a separate company, an “affiliate” of artiste, based in Shenzhen, where he lives. If I get that patent in China, I will also try to convince some of our friends that work at Sunway Taihu Light to run an HPC version of my “Q Entanglement Lab”. I spoke about this in a previous blog post
