Christian Weedbrook

Founder/CEO at @XanaduAI. Quantumpreneur. We are hiring!

[Christian Weedbrook @_cweedbrook]

This is huge for Canada and @XanaduAI!

Up to $390 million in combined government funding is a defining moment for @Xanadu.

Canada and Ontario are expected to back our quantum manufacturing expansion as we move toward going public with $CHAC.

[Xanadu @XanaduAI]

Xanadu has announced up to CAD $390 million in combined government support is under consideration, as it enters negotiations with the Government of @Canada and the @ONgov for support for Project OPTIMISM.

The initiative is expected to significantly advance Xanadu’s roadmap toward utility-scale quantum computing and future quantum data-center infrastructure, offsetting a substantial portion of the capital required to develop the next phase of quantum computing deployment.

If you are an Opendoor shareholder, I have an ask.

Proxy advisors at ISS and Glass Lewis have recommended shareholders to vote against me at our Annual Meeting. I don’t take this personally. This is the fifth time in my career these same people have told people to vote against my team.

These proxy advisors have built no companies and are not meaningful shareholders of OPEN. They're a checkbox industry charging fees to tell other people what to do with shares that aren't theirs.

Usually most companies can’t do anything about this since many institutional shareholders will just vote the way ISS tells them to.

But Opendoor has the Open Army! It is important that we stand up against this separation of management from shareholders.

If you are so inclined, help tilt the world in favor of shareholders and away from bureaucrats.

Find out how (ask your broker, check your emails) and vote your shares. Our board is excellent. We are back on mission and we are winning.

Don't outsource your vote. Read the proxy. Vote your shares.

Four years ago today, Xanadu achieved quantum computational advantage with our quantum computer, Borealis.

Borealis solved a highly complex math problem in just 2 minutes -- a task that would take the world’s best classical supercomputers 7 million years to complete.

[Race @multiplanet1]

Elon Musk fired his longest serving assistant after 12 years and it reveals something brutal about how he thinks.

Mary Beth Brown had been with him since the early SpaceX days. She handled everything. Scheduling. Emails. Logistics. She once said she worked 80 hours a week for over a decade. By all accounts she was irreplaceable.

After 12 years she asked for a raise. A significant one. She felt she'd earned it.

Elon told her to take two weeks off. He said he wanted to see if he could manage without her. When the two weeks ended, he told her he didn't need her anymore.

The internet destroyed him for this. Called him heartless. Ungrateful. Every article framed it as Elon being cruel.

But there's a detail nobody mentions.

He offered her a significant equity package in SpaceX instead of the salary increase. She declined. She wanted the cash.

That SpaceX equity would be worth over $200 million today.

This isn't a story about cruelty. It's a story about two completely different ways of thinking about value. One person optimized for security. The other optimized for asymmetry.

The hardest lesson in business isn't learning how to work hard. It's learning which form of compensation to accept.

Most people choose the paycheck. The ones who build wealth choose the equity.

[Xanadu @XanaduAI]

Last week, Christian Weedbrook (@_cweedbrook), Founder and CEO of Xanadu, took the stage at the Creative Destruction Lab (@creativedlab)'s Super Session to reflect on what it takes to scale a deep-tech company from startup to a public market debut on the TSX and NASDAQ.

According to Christian, surviving the deep-tech grind doesn't just come down to physics — it comes down to human resilience. “You can't stop someone who's not going to give up when it's based on the foundation of learning and enjoying what they're doing.”

Thank you CDL and Sonia Sennik for the great conversation!

Loading classical data into a quantum computer just got 50% cheaper.

This work by Danial Motlagh and Matthew Pocrnic (@mpocrnic97) introduces a new method that slashes the Toffoli gate overhead required for Quantum Read-Only Memory (QROM).

One of the big advantages of @XanaduAI’s photonic approach!

[Photon Capital @PhotonCap]

The quantum computing conversation lives on qubit counts and gate fidelity. The part that decides scaling sits one layer down.

Once you pass the limit of a single chip, fridge, or trap, every modality has to wire modules together with light, and they converge on the same telecom photon, fiber, and single photon detector. IonQ vertically integrating an optics supply chain, the $2B CHIPS Act commitment to quantum foundries, and the resumes of the scientists leading each camp all point at the same place.

My new piece maps the four layer optical interconnect stack and where listed exposure ($IONQ $RGTI $XNDU $GFS $TSEM $COHR) splits.

[Reads with Ravi @readswithravi]

This paragraph by Richard Feynman hits so hard:

“Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn’t matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the best. Don’t think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn’t stop you from doing anything at all.”

Slack was founded in 2009 in Vancouver.

By 2014, their primary headquarters was already in San Francisco.

Today, their standalone valuation is ~$28 billion USD.

Canadian talent builds around the world - but our domestic economy is bleeding our unicorns.

It’s fixable. 🇨🇦👇
