A practical quantum computer must not merely store information, but also process it. To
prevent errors introduced by noise from multiplying and spreading, a fault-tolerant …

Active quantum error correction using qubit stabilizer codes has emerged as a promising,
but experimentally challenging, engineering program for building a universal quantum …

Quantum computers can be protected from noise by encoding the logical quantum
information redundantly into multiple qubits using error-correcting codes,. When …

To run large-scale algorithms on a quantum computer, error-correcting codes must be able
to perform a fundamental set of operations, called logic gates, while isolating the encoded …

We present a comprehensive architectural analysis for a proposed fault-tolerant quantum
computer based on cat codes concatenated with outer quantum error-correcting codes. For …

In this perspective we discuss conditions under which it would be possible for a modest fault-
tolerant quantum computer to realize a runtime advantage by executing a quantum …

We provide a current perspective on the rapidly develo** field of Majorana zero modes
(MZMs) in solid-state systems. We emphasise the theoretical prediction, experimental …

We propose a new class of error-correcting dynamic codes in two and three dimensions that
has no explicit connection to any parent subsystem code. The two-dimensional code, which …

Quantum error correction is believed to be essential for scalable quantum computation, but
its implementation is challenging due to its considerable space-time overhead. Motivated by …

The development of noisy intermediate-scale quantum devices has extended the scope of
executable quantum circuits with high-fidelity single-and two-qubit gates. Equip** these …
