Meet Hilbert; the 100 qubit perfect quantum computer using Cold Atoms for computation

Updated: Sep 2, 2022



Meet "Hilbert", a new quantum computer, which according to coldquanta.com leverages the natural scalability of the Cold Atom Approach. The short version is coldquanta uses lasers to kind of slow down the atoms to make them super cold, basically, to get below five Kelvin. That's when the magic happens. So, the first version of Hilbert working with 100 high-fidelity, gated, long coherence qubits.


The Hilbert team is targeting 1,000 qubits machine by 2024 with strong connectivity, fidelity, and miniaturization at room temperature without refrigeration required. I think Hilbert is an exciting quantum technology and I love to know more about her.


So, where does the name Hilbert come?


I am not a physicist, but if you read any physics-related material which I read a lot about quantum physics and especially quantum computation, the word Hilbert space used at high frequency. If you don't know what it means. here is an easy way to explain it; In mathematics, Hilbert spaces allow generalizing the methods of linear algebra and calculus from Euclidean vector spaces to spaces that may be infinite-dimensional. A Hilbert space is a vector space equipped with an inner product which defines a distance function for which it is a complete metric space - an infinite-dimensional analog of Euclidean space - a vector space!

So, we also should know another bit of physics that helps understand how Hilbert thinks and does what does.


It turns out that cooling rubidium atoms to less than 170 billionths of a degree above absolute zero (using lasers) causes the individual atoms to condense into a "super atom"; therefore behaving as a single entity. The magic, something spooky happens there.


So, the history goes back to July 14, 1955, Science mag published a paper based on a paper from Albert Einstein and Indian physicist Satyendra Nath Bose; predicted that reaching a certain temperature creates an entirely new state of matter. That prediction goes back to Albert Einstein's era and Indian physicist Satyendra Nath Bose on July 14, 1955. I was born 3 weeks later, that makes it 67 year ago. Below see the Science mag which at that time sold for $7.00

Color indicates the density of atoms having the velocity specified by the two horizontal axes. The high-density blue and white spire is an image of low-energy atoms that have condensed into a single quantum state. The average speed of the atoms in the spire is about 0.5 millimeter per second. See page 198 and the related News story on page 152 and the Perspective on page 182. [Image: M. R. Matthews]




That is the very short history of pioneering work that coldquanta scientist have done. So now using the fifth form of matter as the foundation for its Cold Atom Quantum Technology and of course, "Hilbert."


So what can Hilbert do?

In a nutshell, this is how it works; when the atoms cooled to a few millionths of a degree above absolute zero, they take on quantum properties which means we can put them in entanglement state and run gates and circuits on them and compute quantum computations.


To do this, lasers are used to arrange the atoms, hold them in place, run computations on them, and read out the results. Quantum calculations, communications, and sensing are the result. I like to run circuits on Hilbert!


Next post, I will dig into their technology more and learn how Hilbert computer behaves. I will also break down the difference between Cold Atom and Ion Trapping methods.
