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.

History[edit]

IonQ was co-founded by Christopher Monroe and Jungsang Kim, professors at The University of Maryland.[1] and Duke University[2] in 2015[3], with the help of Harry Weller, a partner at venture firm New Enterprise Associates.[4]

The company is an offshoot of the co-founders’ 25 years of academic research in quantum information science.[3] Monroe's quantum computing research began as a postdoctoral researcher under Nobel laureate David Wineland[5] where he led a team using trapped ions to produce the first controllable qubits and the first controllable first quantum logic gate[6], culminating in a proposed architecture for a large-scale trapped ion computer.[7]

Kim and Monroe began collaborating formally as a result of larger research initiatives funded by the Intelligence Advanced Research Projects Activity (IARPA).[8] They wrote a review paper[8] for Science Magazine entitled Scaling the Ion Trap Quantum Processor,[9] pairing Monroe's research in trapped ions with Kim’s focus on scalable quantum information processing and quantum communication hardware.[10]

This research partnership became the seed for IonQ’s founding. In 2015, New Enterprise Associates invested $2 million to commercialize the technology Monroe and Kim proposed in their Science paper.[4]

In 2016, they brought on David Moehring from IARPA—where he was in charge of several quantum computing initiatives[11]—to be the company’s chief executive.[3] In 2017, they raised a $20 million series B, led by GV (formerly Google Ventures) and New Enterprise Associates, the first investment GV has made in quantum computing technology.[12] They began hiring in earnest in 2017,[13] with the intent to bring an offering to market by late 2018.[3][14]

Technology[edit]

IonQ’s hardware is based on a trapped ion architecture, from technology that Monroe developed at the University of Maryland, and that Kim developed at Duke.[12]

In November 2017, IonQ presented a paper at the IEEE International Conference on Rebooting Computing describing their technology strategy and current progress. It outlines using a microfabricated ion trap and several optical and acousto-optical systems to cool, initialize, and calculate. They also describe a cloud API, custom language bindings, and quantum computing simulators that take advantage of their trapped ion system's complete connectivity[15]

IonQ and some experts claim that trapped ions could provide a number of benefits over other physical qubit types in several measures, such as accuracy, scalability, predictability, and coherence time.[16][3][17] Others criticize the slow operational times and relative size of trapped ion hardware, claiming other qubit technologies are just as promising.[18] For more details, see Trapped ion quantum computer.
