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. 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))
