For the first time in history, we are seeing a branching point in computing paradigms with the
emergence of quantum processing units (QPUs). Extracting the full potential of computation …

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 …

We estimate the resources required in the fusion-based quantum computing scheme to
simulate electrolyte molecules in Li-ion batteries on a fault-tolerant, photonic quantum …

Despite significant overhead reductions since its first proposal, magic state distillation is
often considered to be a very costly procedure that dominates the resource cost of fault …

Estimating and reducing the overhead of fault-tolerance (FT) schemes is a crucial step
toward realizing scalable quantum computers. Of particular interest are schemes based on …

To achieve universal quantum computation via general fault-tolerant schemes, stabilizer
operations must be supplemented with other non-stabilizer quantum resources. Motivated …

Treating stabilizer operations as free, we establish lower bounds on the number of resource
states, also known as magic states, needed to perform various quantum computing tasks …

Magic state distillation is one of the leading candidates for implementing universal fault-
tolerant logical gates. However, the distillation circuits themselves are not fault-tolerant, so …

The manipulation of quantum “resources” such as entanglement, coherence, and magic
states lies at the heart of quantum science and technology, empowering potential …
