uQ - an embedded quantum simulator

Hardware Required

The uQ is currently designed for the following hardware (with links to PiHut):

• Raspberry Pi Pico - https://thepihut.com/products/raspberry-pi-pico
• LCD Display Module for Pico - https://thepihut.com/products/1-3-ips-lcd-display-module-for-raspberry-pi-pico-240x240

These parts were chosen as they are very easy to assemble, and give us a nice basic interface; a screen, a small joystick, and some buttons.

Firmware Instructions

Download the pico-sdk and set the correct environment variables:

PICO_SDK_PATH=/path/to/pico-sdk

cd build/
cmake ..

and then run

make -j9

Then press BOOTSEL whilst plugging in the pico into a USB port, which will present as a USB drive. Now move the main.u2f to the drive, it will reboot and flash and you're good!

## What you should see

When you have built the module you should see something like this:

The usage is as follows:

• Use the dpad - up/down/left/right - to navigate the circuit.
• Press the joystick down to change the gates - currently supported gates include:
  • - - the identity gate ('do nothing')
  • X - the NOT gate
  • H - the Hadamard (superposition) gate
  • R - a fixed pi/8 x-axis rotation
  • x - the SWAP gate (MUST come in pairs)
  • V - the square root of the X gate
  • c - the control indicator - adds single qubit control to any given gate in that slice
• Press A to compute the circuit and generate the output state vector
• Press B to clear the circuit
• Press X for the help screen

TODOs

1. Add a decent PRNG (seeded quantumly?) and properly simulate the circuit
2. Add more gates
3. Add support for multiple controls in a single slice (like mcx in qiskit)
