The fragile nature of quantum information

Challenges are very serious when it comes to the nature of quantum information. In effect, due to the fragile nature of quantum information, increasing the computational power requires advances in the quality of the qubits, how the qubits talk to each other and minimizing the quantum errors that can occur.
For those who are unfamiliar, the inherent computational power of a quantum processor to solve practical problems depends on far more than simply the number of qubits.
