Libket
Libket serves as the core of the Ket Quantum Programming platform, providing a runtime library for the quantum programming language Ket, as well as simple interfaces for developing quantum applications in C/C++ and Rust. For more information, please refer to the documentation at https://quantumket.org.

Libket Quantum Programming Library
The Libket library provides a set of tools for quantum programming in Rust. It serves as the runtime library for the Python-embedded quantum programming language Ket.
Note: For more information about the Ket programming language, please visit https://quantumket.org.
Usage
To use this library, add the following line to your Cargo.toml
file:
[dependencies]
libket = "0.3.1"
Additionally, you may need to include the following dependencies for quantum code serialization/deserialization and the KBW quantum computer simulator:
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
kbw = "0.1.6"
Examples
The following example demonstrates the implementation of Grover's algorithm using Libket:
use ket::*;
fn main() -> Result<()> {
let n = 4; // Number of qubits
let p = Process::new_ptr(); // Create a new quantum process
let mut qubits = Quant::new(&p, n)?; // Create a quantum register with `n` qubits
h(&qubits)?; // Apply Hadamard gate to all qubits
let steps = (std::f64::consts::PI / 4.0 * f64::sqrt((1 << n) as f64)) as i32; // Calculate the number of steps for the Grover's algorithm
for _ in 0..steps {
ctrl(&qubits.slice(1..), || z(&qubits.at(0)))??; // Apply controlled-Z gate with the first qubit as the target and the rest as controls
around(
&p,
|| {
h(&qubits).unwrap(); // Apply Hadamard gate to all qubits
x(&qubits).unwrap(); // Apply Pauli-X gate to all qubits
},
|| ctrl(&qubits.slice(1..), || z(&qubits.at(0))), // Apply controlled-Z gate with the first qubit as the target and the rest as controls
)???;
}
let _ = measure(&mut qubits)?; // Perform measurement on the qubits
let mut p = p.borrow_mut();
p.prepare_for_execution()?; // Prepare the quantum program for execution
println!("{:#?}", p.blocks()); // Print the blocks of the quantum program
Ok(())
}
The example demonstrates the usage of various Libket functions to implement Grover's algorithm, including qubit initialization, gate operations, control structures, and measurement.
