Morphing quantum error-correction circuits and their time-like properties
Mac Shaw | Delft University of Technology
Morphing quantum error-correction circuits (sometimes called “middle-out” or “ancilla-free” circuits) are a new way of designing syndrome extraction circuits for quantum error correction codes. In particular, morphing circuits have been applied to the surface code, colour code and to Bivariate Bicycle (BB) codes and have numerous advantages: they reduce the connectivity requirements of each of these codes, allow for the use of ISWAP gates instead of CNOT gates during error correction, and provide a flexible framework for dealing with fabrication defects. In this talk, I will begin with an overview of morphing circuits and our previous work (Lowering Connectivity Requirements For Bivariate Bicycle Codes Using Morphing Circuits) which applied them to bivariate bicycle codes.
Then, I will discuss some newer ongoing work investigating the time-like properties of morphing circuits. In particular, I will show that morphing circuits give improved performance over standard circuits in lattice surgery experiments under a physical noise model in which the reset and measurement error rates are biased. This work continues to add to the advantages that morphing circuits can provide compared to standard syndrome extraction circuits.
