several companies are actively working on developing and offering quantum computers for sale. However, it's important to note that the field of quantum computing is rapidly evolving, and the availability, cost, and specifications of quantum computers may have changed since then. Here are a few prominent companies that were involved in the development of quantum computers at that time:
IBM Quantum: IBM has been at the forefront of quantum computing research and development. They offer access to their quantum systems through the IBM Quantum Experience platform. The systems available include the IBM Q System One and the IBM Q Network. However, they do not sell quantum computers directly to customers.
D-Wave Systems: D-Wave is a company known for developing quantum annealing machines. Their systems, called D-Wave Quantum Computers, are designed for solving optimization problems. They have released multiple generations of their systems, including the D-Wave 2000Q and the Advantage system. Pricing details can be obtained by contacting D-Wave directly.
Rigetti Computing: Rigetti Computing focuses on developing both hardware and software for quantum computing. They offer cloud access to their quantum processors through their Quantum Cloud Services platform. Rigetti's systems include the Rigetti Quantum Virtual Machine (QVM) and the Rigetti Quantum Cloud Processor (QCP). Pricing information can be obtained by contacting Rigetti.
IonQ: IonQ is a company that specializes in developing trapped-ion quantum computers. They aim to create scalable and error-corrected quantum systems. IonQ offers access to their quantum processors through cloud services. As for pricing and specifications, it is advisable to visit IonQ's website or contact them directly.
Honeywell Quantum Solutions: Honeywell is a multinational conglomerate that has ventured into quantum computing. They offer access to their quantum processors through their cloud-based system called the Honeywell Quantum Solution (HQS). Pricing details and specifications can be obtained by reaching out to Honeywell Quantum Solutions.
It's worth mentioning that the cost of quantum computers can vary significantly depending on factors like the number of qubits, coherence times, error rates, and additional services provided. Quantum computers are still in the early stages of development, and their pricing models may evolve as the technology progresses. For up-to-date information on availability, pricing, and specifications, I recommend visiting the respective company websites or contacting them directly.
