[−][src]Function qip::measurement_ops::soft_measure
pub fn soft_measure<P: Precision>(
n: u64,
indices: &[u64],
input: &[Complex<P>],
input_offset: Option<u64>,
multithread: bool
) -> u64
Sample a measurement from a state input
. b
Sample from qubits at indices
and return bits as u64 in order given by indices
. See
measure_prob
for details.
Keep in mind that qubits are big-endian to match kron product standards.
|abc>
means q0=a
, q1=b
, q2=c
Examples
use qip::state_ops::from_reals; use qip::measurement_ops::soft_measure; // Make the state |10>, index 0 is always |1> and index 1 is always |0> let input = from_reals(&[0.0, 0.0, 1.0, 0.0]); let m = soft_measure(2, &[0], &input, None, false); assert_eq!(m, 1); let m = soft_measure(2, &[1], &input, None, false); assert_eq!(m, 0);
