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 …

The technological world is in the midst of a quantum computing and quantum information
revolution. Since Richard Feynman's famous 'plenty of room at the bottom'lecture (Feynman …

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 …

Photonics is the platform of choice to build a modular, easy-to-network quantum computer
operating at room temperature. However, no concrete architecture has been presented so …

Given a quantum gate circuit, how does one execute it in a fault-tolerant architecture with as
little overhead as possible? In this paper, we discuss strategies for surface-code quantum …

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

Nonstabilizerness, also known as “magic,” stands as a crucial resource for achieving a
potential advantage in quantum computing. Its connection to many-body physical …

We present designs for scalable quantum computers composed of qubits encoded in
aggregates of four or more Majorana zero modes, realized at the ends of topological …

We propose examples of a hybrid quantum-classical simulation where a classical computer
assisted by a small quantum processor can efficiently simulate a larger quantum system …

Recent results on the non-universality of fault-tolerant gate sets underline the critical role of
resource states, such as magic states, to power scalable, universal quantum computation …
