Quantum computing is a novel technology that uses quantum physics to address issues that are beyond the capabilities of traditional computers.
Many companies are now attempting to make actual quantum hardware available to tens of thousands of developers, a tool that scientists only dreamed about three decades ago.
As a result, our engineers are frequently deploying increasingly powerful superconducting quantum computers, bringing us closer to the quantum computing speed and capacity necessary to alter the world.
In this post, we’ll take a closer look at quantum computing and the tools and frameworks that go along with it, as well as where they’ll be in 2022.
What is Quantum Computing?
These supercomputers are built on the principles of superposition and entanglement, which are two aspects of quantum physics. Quantum computers can now do tasks at rates that are orders of magnitude faster than traditional computers while using far less energy.
In the 1980s, the area of quantum computing arose. Then it was revealed that quantum algorithms were more efficient than their conventional equivalents in solving certain computer tasks.
Quantum computing is a discipline of computer science that focuses on the advancement of computer technology based on quantum theory concepts. It makes use of the extraordinary ability of subatomic particles to exist in several states at once, such as 0 and 1. They are capable of processing considerably more data than ordinary computers.
The quantum state of an item is used to create a qubit in quantum computing operations. Qubits are the fundamental data units of quantum computing. In quantum computing, they serve the same job that bits do in ordinary computing, but they behave quite differently.
Traditional bits are binary and can only maintain a position of 0 or 1, whereas qubits can include a superposition of all possible states.
Best Frameworks for Quantum Computing
Cirq was built by Google’s Quantum AI team. It’s used to design and improve quantum circuits that are then tested on quantum computers and simulators. Cirq is fantastic since it offers development simulators that are quite similar to those seen in real life.
This implies that the library works its way through the hardware details surrounding NISQ (Noisy Intermediate-Scale Quantum) so that we can be sure that the algorithm or circuit can be run on a real quantum computer after it’s finished.
As a result, it has the potential to be exploited to create adaptive and deployable quantum circuits. It also has interoperability features. A software that imports and exports quantum circuits and simulations, for example.
A framework for programming quantum computers that are open-source. Cirq is a Python software package that allows you to create, manipulate, and optimize quantum circuits before executing them on quantum computers and simulators.
Cirq is an efficient abstraction for dealing with today’s noisy intermediate-scale quantum computers, where hardware requirements are critical for attaining cutting-edge results.
- From gates operating on qubits, you can learn how to design quantum circuits. Learn what a Moment is and how various insertion tactics might assist you in constructing your ideal circuit. Learn how to slice and dice circuits in order to create new and improved circuits.
- Technology restrictions have a significant influence on whether or not a circuit can be implemented on contemporary hardware. Learn how to program Google’s Quantum Computing Service and how to create devices to address these limitations.
- Both wave functions and density matrices have built-in simulators in Cirq. Monte Carlo or full density matrix simulations can be used to tackle noisy quantum channels.
- To execute tests on Google’s quantum processors, Cirq collaborates with Quantum Computing Service.
ETH Zurich created ProjectQ, an open-source quantum computing software architecture. It provides a robust and straightforward syntax for users to create quantum applications in Python. ProjectQ can then convert these scripts to any form of back-end, whether it’s a classical computer simulator or a quantum processor.
ProjectQ can then convert these applications to any sort of back-ends, such as a classical computer simulator or a quantum processor, such as the IBM Quantum Experience platform.
- IT is a high-level programming language for quantum programs.
- It has a modular and adaptable compiler.
- It also offers a number of hardware and software backends.
- A quantum computer library (FermiLib) for solving fermionic issues
- The IBM Quantum Experience chip, AQT devices, AWS Braket, and IonQ service-provided devices can all be used to run quantum algorithms.
- At a higher level of abstraction, quantum programs can be emulated (e.g., mimicking the action of large oracles instead of compiling them to low-level gates)
- On classical computers, quantum programs can be simulated.
The Python framework TensorFlow Quantum (TFQ) is for quantum machine learning. TFQ is a TensorFlow application framework that allows quantum algorithm and machine learning researchers to use Google’s quantum computing frameworks directly from TensorFlow.
TensorFlow Quantum is a program that focuses on quantum data and the creation of quantum-classical hybrid models. It combines Cirq-designed quantum computing techniques and logic with TensorFlow APIs, as well as high-performance quantum circuit simulators.
The TFQ framework can be used to run both traditional and hybrid models, such as Quantum CNN (QCNN). As a result, TFQ can be used for any problem that was previously impossible to answer using traditional approaches. To answer certain real-world problems, start with TFQ to create quantum or quantum-classical hybrid models.
- Researchers can use TFQ to create tensors using quantum datasets, quantum models, and conventional control parameters in a single computational network.
- Tensors are used to store quantum data (a multi-dimensional array of numbers). Each tensor of quantum data is described as a Cirq quantum circuit that creates quantum data on the fly.
- The researcher can use Cirq to prototype a quantum neural network that will be included in a TensorFlow compute graph later.
- The capacity to concurrently train and execute numerous quantum circuits is a major feature of TensorFlow Quantum.
