13 Companies Offering Quantum Cloud Computing Software Services

Initially formulated for researchers, engineers and other experts to gain access to the prohibitively expensive quantum hardware at no cost or — at the very least, something affordable — cloud services have now taken on a life of their own, allowing even a quantum enthusiast with a laptop in their bedroom access to (early stage) quantum processing.

What is Quantum Cloud Computing?

Quantum cloud computing is the advanced way to analyze, stockpile, and remotely control huge amounts of information. In its essence, cloud-based quantum computing is made up of quantum simulators, emulators or processors that are available for use via the cloud. It can be used to connect powerful quantum computer systems to complete compound tasks.

In 2016 (discussed below), IBM connected a small quantum computer to the cloud. This allowed for simple programs to be built and executed on the cloud. A year later, researchers from Rigetti Computing demonstrated the first programmable cloud access using the pyQuil Python library.

Still in the early days of the industry, we are yet to see the true benefits quantum cloud computing could manifest in our everyday lives. One thing is for sure, though: cloud-based quantum computing has empowered the masses to get involved with the nascent industry — and maybe it won’t be too long before we see some major breakthroughs in such sectors like finance and logistics because of it.

Quantum Inspire is the first platform in the world to provide online access to a fully programmable two-qubit electron spin quantum processor called Spin-2, a two-qubit quantum processor hosting two single electron spin qubits in a double quantum dot in isotopically purified 28Si.

Along with the Spin-2 is the Starmon-5, which consists of five superconducting transmon qubits in an X configuration.

Next to the quantum chips, the platform gives access to QX, a quantum emulator backend. Two instances of the QX emulator are available, emulating up to 26 qubits on a commodity cloud-based quantum server and up to 31 qubits using one ‘fat’ nodes on Cartesius, the Dutch national supercomputer of SurfSara. Circuit-based quantum machine learning algorithms can be created through a graphical user interface or through the Python-based Quantum Inspire SDK, providing a backend for the projectQ framework, the Qiskit framework. Quantum Inspire provides a knowledge base with user guides and some example algorithms written in cQASM.
