Second Generation Qubits: Error-Protected Qubits

In my mind, in the last two decades, the first generation qubits were shown to be fragile and prone to errors. In terms of computing technological developments, first generation qubits are reminiscent of vacuum tubes. The development of the transistor transformed electronics because it was less error prone. Similarly, I believe the second generation qubits will transform quantum computing by engineering inherently error-protected qubits, opening new avenues towards fault tolerant quantum computation. Two principles guide the engineering of second generation qubits: 1) the physical laws provide immunity from certain errors (e.g. Majorana circuits),2) engineered qubits that autonomously implement quantum error correction (e.g. some bosonic codes implementations and the small logical qubit). I will give an overview on first generation qubits and motivate the underlying advantages of second generation qubits. I will then discuss the recent progress and challenges in the experimental realization of these systems.
