From the project
General Purpose 8 Qubit Optical Quantum Computer
Computer with built-in General Purpose 8 Qubit Optical Quantum Processor
We're beginning to layout the components and finalize the design of our quantum computer! As we continue to design the PCB, we are also working with optical engineers to make our logic gates more compact which will enable us to shrink the design even further than we already have!
To speed up R&D, we've decided to replace the ARM CPU with a QSeven2.0 spec'd "computer on module". There are a variety of benefits to doing this, one major benefit being that we can switch between a variety of x86 and ARM processors.

8Q: common questions
What microcontroller does the 8Q use?
The 8Q is built around the STM32F429BITx, from the STM32 family.
How big is the 8Q PCB?
The 8Q measures 482.5 × 711 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 8Q?
157 components, from 48 distinct parts. The full bill of materials is listed on this page.
Where can I download the 8Q design files?
From the Spooky-Manufacturing/8Q repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the 8Q design in my own project?
Yes, under the terms of its GPL-3.0 license, which Spooky-Manufacturing chose for the repository.
Can I test firmware for the 8Q without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
