Quasar

Quasar is designed as a Domain Specific Language embedded inside a Python programming language. It simplifies writing quantum assembly code by translating high level if statements into a sequence of controlled quantum commands. It can be easily integrated with OpenQASM, IBM Qiskit or Google Cirq.

Using Quasar you can write your quantum programs more easily and have them translated to a quantum assembly language automatically.

Python + Quasar

prgm = Program()

input_qubits = prgm.Qubits([0, 0, 0])
output_qubit = prgm.Qubit()

prgm += If(All(input_qubits)).Then(X(output_qubit))
