Japan just built a quantum computer where every single piece, hardware and software, is homegrown, and then let the world log into it from a browser.
The machine went live at the University of Osaka's quantum center, built with RIKEN and a group of Japanese companies. What makes it different is not raw power. It is independence. Quantum computers normally depend on a handful of foreign suppliers for their most exotic parts, especially the dilution refrigerator that chills the chip. Japan replaced those imports with domestic alternatives and wrote the entire software stack itself, from front end to back end, released as open source.
That last part matters more than the headline suggests. Access to quantum hardware has mostly meant renting time from a few giant corporations. An open-source toolchain means researchers anywhere can see how the machine is actually driven instead of poking a black box.
Now the honest part, because a claim like this deserves it. Cloud access to quantum computers is not new. IBM opened a five-qubit processor to the public back in 2016, and today several companies let anyone run jobs on real quantum hardware. Japan's earlier machines were restricted to domestic non-commercial research. What is genuinely new here is a complete national quantum stack, built end to end, opened up rather than locked down.
And the physics inside is still the strangest thing humans have ever engineered. The chip sits in that gold chandelier you see in the image, cooled to a few thousandths of a degree above absolute zero, colder than deep space. At that temperature, circuits stop behaving like circuits and start behaving like quantum objects, holding states that are neither one nor zero until you look.
We are not at the point where these machines break encryption or redesign drugs. Today's quantum computers make errors constantly and need armies of qubits to correct them.
But this is what the beginning of an industry looks like. Not a finished product. A machine anyone can log into and learn on.
If you had one hour on a quantum computer, what would you try to solve?
@spaceandtech_ I'm glad to see more and more countries join the fierce space race. It seems like the time is approaching when we go back and forth between the stars.
Tesla Diner’s first anniversary is turning into a robotics showcase!
Tesla Diner in Hollywood is preparing to celebrate its first anniversary on July 21 with special events and displays.
• Cybercab and Optimus robots are expected to be featured during the celebrations.
• Roller-skating servers will return as part of the anniversary activities.
• Franz von Holzhausen will personally sign merchandise for early orders.
• The location continues to draw strong visitor interest and positive feedback.
The diner has become one of Tesla’s more visible brand experiences outside its core products.
Elon Musk:
“Starship is the most complicated machine ever made by humans
By a long shot
Any project I can think of would be easier than this, and that’s why no one has built a fully reusable orbital rocket”
SpaceX is not just building another rocket. It is building the infrastructure needed to make space usable at scale
Starship could become the vehicle that enables humanity to build a civilization far beyond Earth....a true multiplanetary civilization among the stars
