Quantum Computing Companies:
IonQ is a quantum computing hardware and software company based in College Park, Maryland. They are developing a general-purpose trapped ion quantum computer and software to generate, optimize, and execute quantum circuits.
Aliro Technologies, a spin-out of Harvard's Quantum Information Sciences Lab, makes software that facilitates accessibility to present-day quantum computers. It offers a hardware-independent platform for developers to write quantum software and helps optimize it according to the specific details of the device, or, conversely, selects the device that maximizes a program's performance. Aliro's software lowers the barrier to entry for businesses that are ready to discover the amazing potential that quantum computing offers.
Rigetti Computing is a privately-held company that operates in the commercial products & office supplies industry. It builds quantum computers and the superconducting quantum processors that power them. It also develops Quantum Cloud Services (QCS), a platform that enables the company's machines to be integrated into a public, private or hybrid cloud.
