Implementing generalized measurements with superconducting qubits
Justin Dressel, Todd A. Brun, Alexander N. Korotkov
We describe a method to perform any generalized purity-preserving measurement of a qubit with techniques tailored to superconducting systems. First, we consider two methods for rea…
Fault tolerance for holonomic quantum computation
Ognyan Oreshkov, Todd A. Brun, Daniel A. Lidar
We review an approach to fault-tolerant holonomic quantum computation on stabilizer codes. We explain its workings as based on adiabatic dragging of the subsystem containing the lo…
General quantum error-correcting code with entanglement based on codeword stabilized quantum code
Jeonghwan Shin, Jun Heo, Todd A. Brun
In this paper, we introduce a unified framework to construct entanglement-assisted quantum error-correcting codes, including additive and nonadditive codes, based on the codeword s…
Compatibility of state assignments and pooling of information
Todd A. Brun, Min-Hsiu Hsieh, Christopher Perry
We say that two (or more) state assignments for one and the same quantum system are compatible if they could represent the assignments of observers with differing information about…
On the Relation between the Psychological and Thermodynamic Arrows of Time
Leonard Mlodinow, Todd A. Brun
In this paper we lay out an argument that generically the psychological arrow of time should align with the thermodynamic arrow of time where that arrow is well-defined. This argum…
A Fault-Tolerant Scheme of Holonomic Quantum Computation on Stabilizer Codes with Robustness to Low-weight Thermal Noise
Yi-Cong Zheng, Todd A. Brun
We show an equivalence relation between fault-tolerant circuits for a stabilizer code and fault-tolerant adiabatic processes for holonomic quantum computation (HQC), in the case wh…
