Holographic quantum codes with trapped ions
Alex Steiner, Gerard Anglès Munné, Robert Freund +9
Holography is a central concept at the intersection of gravity, condensed matter theory, and quantum information, linking the interior bulk of a system to its boundary. A model rea…
Electronically-controlled one- and two-qubit gates for transmon quasicharge qubits
Nicholas M. Christopher, Deniz E. Stiegemann, Abhijeet Alase +1
Superconducting protected qubits aim to achieve sufficiently low error rates so as to allow realization of error-corrected, utility-scale quantum computers. A recent proposal encod…
Microwave Circulation in an Extended Josephson Junction Ring
Dat Thanh Le, Arkady Fedorov, Thomas M. Stace
Circulators are nonreciprocal devices that enable directional signal routing. Nonreciprocity, which requires time-reversal symmetry breaking, can be produced in waveguides in which…
The superconducting grid-states qubit
Long B. Nguyen, Hyunseong Kim, Dat T. Le +9
Decoherence errors arising from noisy environments remain a central obstacle to progress in quantum computation and information processing. Quantum error correction (QEC) based on…
Circuit Quantisation from First Principles
Yun-Chih Liao, Ben J. Powell, Thomas M. Stace
Superconducting circuit quantisation conventionally starts from classical Euler-Lagrange circuit equations-of-motion. Invoking the correspondence principle yields a canonically qua…
Tensor-network decoders for process tensor descriptions of non-Markovian noise
Fumiyoshi Kobayashi, Hidetaka Manabe, Gregory A. L. White +3
Quantum error correction (QEC) is essential for fault-tolerant quantum computation. Often in QEC errors are assumed to be independent and identically distributed and can be discret…
