Feasibility of Scalable Quantum Computers

Nonadiabatic holonomic quantum computation as one of the key steps to achieve fault tolerant quantum information processing has so far been realized in a number of physical settings. However, in some physical systems particularly in spin qubit systems, which are actively considered for realization of quantum computers, experimental challenges are undeniable and the lack of a practically feasible and scalable scheme that supports universal holonomic quantum computation all in a single well defined setup is still an issue. Here, we propose and discuss a scalable star-shape architecture with promising feasibility, which may open up for realization of universal (electron-)spin-based nonadiabatic holonomic quantum computation.

As one of the key steps to achieve fault-tolerant quantum-information processing, nonadiabatic holonomic quantum computation has so far been realized in a number of physical settings. However, in some physical systems, particularly spin-qubit systems (which are actively considered for the realization of quantum computers), the experimental challenges are undeniable, and the lack of a practically feasible and scalable scheme that supports universal holonomic quantum computation all in a single well-defined setup is still an issue. Here, we propose and discuss a scalable star-shaped architecture with promising feasibility, which may pave the way for the realization of universal (electron-)spin-based nonadiabatic holonomic quantum computation.

We demonstrate how a scalable superconducting-qubit-based quantum computer can be realized by performing deterministic quantum gates on microwave photons. We discuss experimental feasibility of our approach.
