Blueprint for fault-tolerant qubits

Building a quantum computer is a challenging task because of the fragility of quantum bits. To deal with this problem, various types of active error correction techniques have been developed. In contrast, researchers have now proposed a design for an inherently fault protected circuit with passive error correction that could significantly accelerate the construction of a quantum computer with a large number of qubits.
