A Unitary Encoder for Surface Codes
Pei-Kai Tsai, Shruti Puri
The surface code is a promising candidate for fault-tolerant quantum computation and has been implemented in many quantum hardware platforms. In this work, we propose a new non-loc…

Mitigating Temporal Fragility in the XY Surface Code
Pei-Kai Tsai, Yue Wu, Shruti Puri
An important outstanding challenge that must be overcome in order to fully utilize the XY surface code for correcting biased Pauli noise is the phenomena of fragile temporal bounda…
