Holonomic quantum gates via continuous measurement in bosonic codes: GKP and cat states
Juan Garcia-Nila, Anirudh Lanka, Todd A. Brun
We apply continuous measurement-based holonomic quantum computation (CMHQC) to bosonic quantum error-correcting codes and develop explicit protocols for both four-component cat cod…
Universal Weakly Fault-Tolerant Quantum Computation via Code Switching in the [[8,3,2]] Code
Shixin Wu, Dawei Zhong, Todd A. Brun +1
Code-switching offers a route to universal, fault-tolerant quantum computation by circumventing the limitation implied by the Eastin-Knill theorem against a universal transversal g…
Adaptive Loss-tolerant Syndrome Measurements
Yuanjia Wang, Todd A. Brun
In the presence of qubit losses, the building blocks of fault-tolerant error correction (FTEC) must be revisited. Existing loss-tolerant approaches are mainly architecture-specific…
Steering paths mid-flight for fault-tolerance in measurement-based holonomic gates
Anirudh Lanka, Juan Garcia-Nila, Todd A. Brun
Continuous measurement-based holonomic quantum computation provides a route to universal logical computation in quantum error correcting codes. We introduce a fault-tolerant framew…
Protection of Exponential Operation using Stabilizer Codes in the Early Fault Tolerance Era
Dawei Zhong, Todd A. Brun
Quantum error correction offers a promising path to suppress errors in quantum processors, but the resources required to protect logical operations from noise, especially non-Cliff…
Weakly Fault-Tolerant Computation in a Quantum Error-Detecting Code
Christopher Gerhard, Todd A. Brun
Many current quantum error-correcting codes that achieve full fault tolerance suffer from having low ratios of logical to physical qubits and significant overhead. This makes them…
