Bosonic Cyclic Codes: Trading Stabilizers for Gaussian Non-Clifford Phase Gates
Owen C. Wetherbee, Yijia Xu, Victor V. Albert +2
Bosonic codes offer hardware-efficient approaches to quantum error correction, with the best encodings offering effective protection of idle quantum information against loss and de…
Error semitransparent universal control of a bosonic logical qubit
Saswata Roy, Owen C. Wetherbee, Valla Fatemi
Bosonic codes offer hardware-efficient approaches to logical qubit construction and hosted the first demonstration of beyond-break even logical quantum memory. However, such accomp…
A Mathematical Structure for Amplitude-Mixing Error-Transparent Gates for Binomial Codes
Owen C. Wetherbee, Saswata Roy, Baptiste Royer +1
Bosonic encodings of quantum information offer hardware-efficient, noise-biased approaches to quantum error correction relative to qubit register encodings. Implementations have fo…
Synthetic high angular momentum spin dynamics in a microwave oscillator
Saswata Roy, Alen Senanian, Christopher S. Wang +10
Spins and oscillators are foundational to much of physics and applied sciences. For quantum information, a spin 1/2 exemplifies the most basic unit, a qubit. High angular momentum…
