| description | We propose a protocol for bosonic binomial-code nonadiabatic holonomic quantum computation in a system composed of an artificial atom ultrastrongly coupled to a cavity resonator. In our protocol, the binomial codes, formed by superpositions of Fock states, can greatly save physical resources to correct errors in quantum computation. We apply to the system strong driving fields designed by shortcuts-to-adiabatic methods. This reduces the gate time to tens of nanoseconds. Noise induced by control imperfections can be suppressed by a systematic-error-sensitivity nullification method. As a result, this protocol can rapidly (∼35ns) generate fault-tolerant and high-fidelity (≳98% with experimentally realistic parameters) quantum gates. |
