Remote entanglement need not be the bottleneck for modular trapped-ion quantum computing
Felix W. Knollmann, David P. Nadlinger, John Blue +7
Modularity underpins classical computing; as quantum processors encounter limits on fabrication yield, reliability, and size, they will also need it acutely. The bottleneck to link…

Generalized Bicycle Codes as Cyclic Submodules and their Automorphism Structure
AJ Davenport, John Blue, Isaac Chuang
Automorphisms of quantum codes, when they exist, offer a pathway toward fault-tolerant gate implementation via qubit relabeling. Although useful, the conditions under which automor…

A log-depth in-place quantum Fourier transform that rarely needs ancillas
Gregory D. Kahanamoku-Meyer, John Blue, Thiago Bergamaschi +2
When designing quantum circuits for a given unitary, it can be much cheaper to achieve a good approximation on most inputs than on all inputs. In this work we formalize this idea,…
