Noise in Digital and Digital-Analog Quantum Computation

  title={Noise in Digital and Digital-Analog Quantum Computation},
  author={Paula Garc'ia-Molina and Ana Martin and Mikel Sanz},
Quantum computing makes use of quantum resources provided by the underlying quantum nature of matter to enhance classical computation. However, current Noisy Intermediate-Scale Quantum (NISQ) era in quantum computing is characterized by the use of quantum processors comprising from a few tens to, at most, few hundreds of physical qubits without implementing quantum error correction techniques. This limits the scalability in the implementation of quantum algorithms. Digital-analog quantum… Expand
