qrisp.jasp.Jaspr.to_qasm#

Jaspr.to_qasm(*args)[source]#

Compiles the Jaspr into an OpenQASM 2 string. Real-time control is possible as long as no computations on the measurement results are performed.

Parameters:

*argslist: The arguments to call the QuantumCircuit evaluation with.

Returns:

str: The OpenQASM 2 string.

Examples

We create a simple script and inspect the QASM 2 string:

from qrisp import *
from qrisp.jasp import make_jaspr

def main(i):

    qv = QuantumVariable(i)
    cx(qv[0], qv[1])
    t(qv[1])
    return qv

jaspr = make_jaspr(main)(2)

qasm_str = jaspr.to_qasm(2)
print(qasm_str)
# Yields

# OPENQASM 2.0;
# include "qelib1.inc";
# qreg qb_59[1];
# qreg qb_60[1];
# cx qb_59[0],qb_60[0];
# t qb_60[0];        

It is also possible to compile simple real-time control features:

def main(phi):

    qf = QuantumFloat(5)
    h(qf)
    bl = measure(qf[0])

    with control(bl):
        rz(phi, qf[1])
        x(qf[1])

    return

jaspr = make_jaspr(main)(0.5)
print(jaspr.to_qasm(0.5))

This gives:

OPENQASM 2.0;
include "qelib1.inc";
qreg qb_59[1];
qreg qb_60[1];
qreg qb_61[1];
qreg qb_62[1];
qreg qb_63[1];
creg cb_0[1];
h qb_59[0];
h qb_60[0];
h qb_61[0];
reset qb_61[0];
h qb_62[0];
reset qb_62[0];
h qb_63[0];
reset qb_63[0];
measure qb_59[0] -> cb_0[0];
reset qb_59[0];
if(cb_0==1) rz(0.5) qb_60[0];
if(cb_0==1) x qb_60[0];
reset qb_60[0];
