Quantum Computing Competitive Analysis
A competitive analysis of D-Wave, Google, Honeywell, and IBM has been provided in the attached spreadsheet. Below is a summary of the key findings.
Summary of Findings
- D-Wave systems primarily focus on a process called quantum annealing to find solutions for problems. Since quantum computers are probabilistic and not deterministic, they provide good answers within a short time. They offer thousands of samples within a second, which ensures that the best solution is found while providing other viable alternatives.
- Google built the first quantum computer that can solve complex problems, which cannot be solved even by the best traditional computer in the world. The computer's Sycamore processor helped Google achieve quantum supremacy.
- Honeywell’s System Model HO has a quantum volume of 64 bits, which make it twice as powerful as those of its competitors. The company also plans to add more qubits to their computer “each year or the next five years, increasing its quantum volume by a factor of 10 each time.”
- IBM is continuously working to increase quantum volume and plans to continue investing in system integration, software innovations, and foundational hardware. In addition, many of IBM’s quantum systems are available to the public .
