How it works
This design simulates a universal one-qubit quantum computer.
It can execute 8 operations:
- Reset the state to |0>
- Apply a X/Y/Z/H/S/T gate to the qubit (see https://en.wikipedia.org/wiki/Quantum_logic_gate for gate definitions)
- Measure and returned the result, upon which the state will collapse to the measured value
Amplitudes are stored in 8 bit fixed point numbers, where the value v is indicated by the binary value round(127 * v). A LFSR is used to generate pseudorandom numbers for measurement.
How to test
ui_in[2:0] indicate which operation should be executed. ui_in[3] contains the start signal, inverting its value will make the chip run the operation.
If the operation was the measure operation, the result can be read from uo[0]. After the operation was executed, the chip inverts the value of the done signal on uo[1] to match that of ready signal and waits for another command.
