The path to the next generation of processors. Faster. All silicon. Atomic Scale. Greatly reduced power consumption. Room temperature operation. Classical computing, quantum computing, and hybrid devices.

At Quantum Silicon Inc. we develop the world's finest practical devices for field controlled computing. QSi devices compute by rearranging a fixed collection of electrons. This is practical, very fast, and very energy-efficient.

Our atomic-scale, ultra-low-power field controlled computing devices are based on unique Quantum Dots that each consist of a single silicon atom. They are orders of magnitude faster than the best conceivable CMOS devices, but fully compatible with them on the same chip.


Binary Computing: Tiny, fast, and cool

QSi is changing the face of computing. We have created the first practical implementation of an atomic scale architecture that does not use transistors.  


Why does that matter?  Ordinary computer circuits pump enormous numbers of electrons with each cycle of the clock. Then all those electrons are dumped as heat. It is extremely expensive to get rid of all that heat. That has forced an end to the Moore’s Law path that has driven all aspects of the computing industry for the past half century.  So computers are not getting any faster.  It takes a lot of energy to run them. That energy is all wasted. QSi has shown that it doesn’t have to be that way. 


How do we do it?  The Quantum Silicon approach harnesses electrons in collections of silicon atoms to represent, transmit, and create information. Our process does not use electric current.  The result is a new generation of computing circuits that are tiny, fast, and cool.  Using this approach, QSi creates classical computing devices, quantum computing devices, and hybrid classical/quantum devices tailored to solve previously intractable problems.  

• Silicon based allowing integration into today’s architecture

• Room temperature binary devices at hundreds of gigahertz, or even faster

• 1000X less power consumed than the best of today’s technology

Quantum Computing

In contrast to the large and unwieldy quantum computing designs considered to date, QSi’s design uses atomically-precise fabrication methods to create unique atom-scale, all-silicon quantum computing machines that do not require extreme cryogenic conditions.


The inherent extreme small size, atomically precise uniformity of constituent parts and complete compatibility with conventional silicon electronics allows for a new generation of quantum computing engines.


Uniquely, QSi’s machines will operate at relatively high temperatures, removing the need for bulky and expensive cooling. And the incomparably small and uniform structures we make reduce complexity, make for simpler operation requirements while creating the real prospect of portable quantum computing.

Atomic White Out

January 03, 2023

Although patterning of atomic silicon quantum dots (ASiQDs) to create nanoelectronic devices has been possible for some years, even the best patterning technique has been susceptible to occasional error. This paper demonstrates the mechanochemistry bonding of a single hydrogen atom to a ASiQD or erase or “passivate” it, opening the door for larger and more elaborate ASiQD structures and furthering scalability of the paradigm.
