Physicist John Preskill called this the Noisy Intermediate-Scale Quantum (NISQ) era as physicist and engineers are still working hard to solve all technical challenges.
Are there potential solutions to make computer more resistant to distubances? In classical computing and communication, error correcting codes are introduced to correct for noise; for instance, if someone cannot hear what you say, you repeat your message. Impressive work has been done to generalize the concept of error correction codes into quantum error correction for an overview, see the now classical textbook by Michael Nielsen and Isaac Chuang.13 To correct errors in one qubit, however, requires the use of several qubits, and the technological race is still to scale up quantum, computers for large scale operations.
