How Xanadu’s Photonic Quantum Computers Work

The Xanadu Quantum Cloud is the first cloud platform offering access to photonic quantum computers via its silicon photonic chips. Learn how these chips generate and process quantum information through a series of innovative squeezers (the inputs), a fully programmable interferometer (the gates), and photon detectors (the outputs).

These chips are a core component of Xanadu’s roadmap for fault-tolerant quantum computers and offer unique applications in quantum chemistry, finance and logistics.

Came for the processor! Stayed for the top notch animation 👌

Having quantum computers perform processes on classical electronic based chips is like running a marathon when you only know how to crawl. photonics is the way forward for quantum computing without a doubt.

Quantum computers will allow logic-relational-constraint languages to work in large programs, these languages take an exponential amount of time to compute as you linearly increase the number of goals or constraints. You could also evolve programs that work via merging two arbitrary programs together at various points and figure out which one makes a valid useful program...

That’s dope. The future holds all sorts of crazy possibilities and I can’t wait to see it!

Quantum Computing at the Speed of Light!

[davidbain]

Just wondering who did your animation? It's really slick! Also, what is the limiting factor for the number of qubits?

Nice work Xanadu. Looking forward to solve all issues for the scale up

[NewsNow]

This technology could be your big break. Don't look back 20 years later and regret now getting involved.

[tossancuyota]

Now we can say RGB increases the performance lol 😂

[SkiNet]

This technology is so wonderfull it will change the world as we know it

[MuonRay]

Very interesting. I wonder are some of the coding applications mentioned for use in this type of hardware are quantum annealing type problems based on meta-heuristic algorithms which have been implemented on adiabatic-styled quantum computer's in the recent past, such as the d-wave quantum computer? I ask because I have been developing ways to equate quantum algorithms to more classical theories of network synchronization that could be run on more portable classical computing hardware.

The quantum soul, making machines with souls like us😮

I AM A COMPUTER ENGINEER. NICE TO GET TO KNOW A COMPANY THROUGH YOUTUBE. Potential Employer! :) Ha ha.
Still, in direct touch with Companies on the Cutting Edge.

0:58 the inputs all cover a different distance on their way to the squeezers, i'm curious how the photon packets are timed so accurately. i'm guessing the actual photon paths look quite different.

I don't understand something here; the Xanadu website, as well as other articles, says that their photonic quantum computers work at room temperature, but their photon detectors, the transition edge sensors, need to be kept in a superconductive state in order to work, which requires cryogenic cooling.

Which is it then? Does the machine require cryogenic cooling, and thus does not truly perform at room temperature, or have they invented a new type of transition edge sensor that can work at room temperature?

How do you entangle the squeeze states if they are photons?

[hamedhaidari]

a random question: in what other industries would this technology be game changing and could you mention some theoretical examples?

[abhikbanerjee]

Available, but is it free for students and like? Sounds amazing.

SSB Pulse-evolution, like coherence-cohesion objectives in flat-space.
The faster the clock speed the closer it gets to a resonating Analog Quantum Computer phase-locked to real-time logarithmic projection-drawing coordination.

It's the human brain that still unbeatable. It's computation and genius is super exponential.
