'Quantum hard drives' closer to reality after scientists resolve 10-year-old problem

Scientists say they have cracked a decade-old problem that could bring the concept of a "quantum hard drive" closer to reality.
The solution involved developing a new type of error-correction system for stabilizing qubits — the building blocks of quantum information — against interference, overcoming a major hurdle facing the development of practical quantum computers.
If successfully scaled, the technique could pave the way for highly efficient quantum memory systems capable of storing huge volumes of quantum data, researchers claimed in a new study published Nov. 4 in the journal Nature Communications.
