FLZ Physics and Sideband Gates in Python

Sat, 09 Aug 2025 00:00:00 +0000

This post demonstrates how to calibrate sideband gates in Python using the Floquet-Landau-Zener (FLZ) physics. The code is designed to be run in a Jupyter Notebook or as a standalone Python script. It uses the scqubits and qutip libraries to simulate the dynamics of a superconducting circuit and analyze the results.

This was run with:
Python version: 3.11.10 (main, Nov 26 2024, 19:12:45) [Clang 16.0.0 (clang-1600.0.26.4)]
Qutip version: 5.1.1
scqubits version: 4.3

Some Setup

All the code for this can be found in this Jupyter Notebook and FloquetDemo.py.

Hello World

A sample go program is show here.

package main

import "fmt"

func main() {
 message := greetMe("world")
 fmt.Println(message)
}

func greetMe(name string) string {
 return "Hello, " + name + "!"
}

Run the program as below:

$ go run hello.go

Variables

Normal Declaration:

var msg string
msg = "Hello"

Shortcut:

msg := "Hello"

Constants

const Phi = 1.618

Basic Types

Mon, 01 Jan 0001 00:00:00 +0000

Strings

str := "Hello"

Multiline string

str := `Multiline
string`

Numbers

Typical types

num := 3 // int
num := 3. // float64
num := 3 + 4i // complex128
num := byte('a') // byte (alias for uint8)

Other Types

var u uint = 7 // uint (unsigned)
var p float32 = 22.7 // 32-bit float

Arrays

// var numbers [5]int
numbers := [...]int{0, 0, 0, 0, 0}

Pointers

func main () {
 b := *getPointer()
 fmt.Println("Value is", b)

func getPointer () (myPointer *int) {
 a := 234
 return &a

a := new(int)
*a = 234

Pointers point to a memory location of a variable. Go is fully garbage-collected.

Flow Control

Mon, 01 Jan 0001 00:00:00 +0000

Condition

if day == "sunday" || day == "saturday" {
 rest()
} else if day == "monday" && isTired() {
 groan()
} else {
 work()
}

if _, err := doThing(); err != nil {
 fmt.Println("Uh oh")

Switch

switch day {
 case "sunday":
 // cases don't "fall through" by default!
 fallthrough

 case "saturday":
 rest()

 default:
 work()
}

Loop

for count := 0; count <= 10; count++ {
 fmt.Println("My counter is at", count)
}

entry := []string{"Jack","John","Jones"}
for i, val := range entry {
 fmt.Printf("At position %d, the character %s is present\n", i, val)

n := 0
x := 42
for n != x {
 n := guess()
}

Bash Variables

Variable

NAME="John"
echo $NAME
echo "$NAME"
echo "${NAME}

Condition

if [[ -z "$string" ]]; then
 echo "String is empty"
elif [[ -n "$string" ]]; then
 echo "String is not empty"
fi
