Kamehame-Hadamard!
A quantum computing SDK in pure Go — build, simulate, transpile, and run quantum circuits with zero external dependencies.
package main
import (
"fmt"
"github.com/splch/goqu/circuit/builder"
"github.com/splch/goqu/sim/statevector"
)
func main() {
c, _ := builder.New("bell", 2).
H(0).
CNOT(0, 1).
MeasureAll().
Build()
sim := statevector.New(2)
counts, _ := sim.Run(c, 1024)
fmt.Println(counts) // map[00:~512 11:~512]
}go get github.com/splch/goqu@latest
Requires Go 1.24+.
