UNIX Philosophy

1. Write programs that do one thing and do it well.
2. Write programs to work together.
3. Write programs to handle text streams, because that is a universal interface.

Different concerns

• Parse the file
• Simulate circuit
  • Optimise expression (find ordering, slice, etc)
  • Actually simulate

Example of usage

Simulator program: tensim

• Simply simulate a circuit:

cat circuit | tensim > result

• Simulate a circuit in a wierd format

  cat circuit | tensim parse -f wierd | tensim > result
  

  1. Why not tensim --input-fmt wierd?

• Simulate N generated circuits in one command

generate_circ -n 1 >> circuits
generate_circ -n 2 >> circuits
....
cat circuits | tensim > results

• Simulate circuit based on Hamiltonian composed of tensor network, not gates

gen_tensor_net | tensim optimize | tensim simulate > result
