Quantum Computer Simulation

This is a quantum computer simulation research project. It's probably not accurate to a real quantum computer.

Build instructions

git clone https://github.com/noClaps/qcsim.git && cd qcsim
cargo run

Usage

You should start by initialising the quantum computer with a specified number of qubits:

use qcsim::Computer;

fn main() {
  let qc = Computer::new(3);
}

This will initialise them in the $\ket{00\dots0}$ state.

After this, you can use array indexing to apply operations to the qubits in the computer, using the gates you have available:

• pauli_x
• pauli_y
• pauli_z
• hadamard
• phase
• pi_by_8
• controlled_not
• controlled_z
• swap
• toffoli

For example:

qc.hadamard(0);
qc.controlled_not(0, 1);
qc.toffoli(0, 1, 2);

Once you're done, you can output the state of the system using measure:

println!("{}", qc.measure());

This will return the measured state of the entire computer as a string, along with taking ownership of the computer instance so that no more operations can happen, since the state should only be measured at the very end.
