A quantum computer based on 2D trapped ion arrays

Trapped ions are among the leading approaches for realizing quantum computers, since they combine  high-fidelity quantum gates, long coherence times and long-range connectivity.  However, radio-frequency electric fields for confinement used in the traditional approach present several challenges to scaling,  restricting transport and placement of ions along with a host of technical challenges.  ZuriQ is building a novel quantum computing architecture that removes these restrictions by replacing the radio-frequency field with a large  magnetic field that natively supports two-dimensional arrays and transport in three dimensions. The unique features of our Penning micro-trap approach open up new possibilities for a hardware architecture with improved connectivity and flexibility that can not only push forward quantum computing, but also find applications in quantum sensing of electric and magnetic fields with excellent spatial resolution. The technology is being spun out of research at the TIQI group of Prof. Home where we have demonstrated full quantum control of ions in this novel setting.

Speaker

Dr. Pavel Hrmo - CEO ZuriQ/ Postdoc at TIQI - ETH
Pavel has 10 years of experience with trapped ions in various guises. During his PhD at Imperial College London he worked to bring fundamental quantum control techniques from radio-frequency traps to Penning traps for the first time dreaming that one day they could be used to build a quantum computer. He then moved to the University of Innsbruck to the world-renowned lab of Prof. Rainer Blatt to work on scaling quantum computation in radio-frequency surface chip traps with mixed ionic species. While there he co-developed a novel entangling gate mechanism for ions that storage information in more levels than just two levels. Three years ago, he joined the Penning team at ETH Zürich where he contributed to the development of the key Penning trap technology behind ZuriQ - the company he co-founded and now leads as CEO
