V lang Quantum Simulator

This is a very basic implementation of a Quantum Simulator in Vlang to learn the basic concepts. You can understand how work a quamtum computer from the code. The code is devide in two parts, one part allow you create Quantum circuits with basic Quantum Gates, and you can execute it using plain vlang

Components

• structs

  • Gates: x, rx, ry, rz, z, y, h, cx, m

  • Quantum Circuit

  • Quantum Simulator:

    • imput: Quantum Circuit
    • outputs:
      • statevector

Install

Visit https://vlang.io and install the language

git clone https://github.com/ismaelfaro/V_lang-quantum-simulator.git

cd V_lang-quantum-simulator

Run

v run .

Example:

qubits := i32(10)

mut qc := QuantumCircuit{qubits: qubits}

qc.h(0)
qc.h(1)
qc.h(2)
qc.h(3)
qc.h(4)

qc.cx(0,5)
qc.cx(1,6)
qc.cx(2,7)
qc.cx(3,8)
qc.cx(4,9)

println(qc)

mut qsim := QuantumSimulator{qubits: qubits, circuit: qc}
qsim.init()
qsim.run(1024)

print(qsim) 

TODO:

• refactor the code to be more Vlang friendly
• fix the outputs for
  • counts
  • memory
