DESCRIPTION:Linnea Grans-Samuelsson\nPlease join us for the Junior Quant
 um Seminar with Linnea-Grans-Samuelsson from the University of Oxford w
 ho will give the talk "Improved Pairwise Measurement-Based Surface Code"
  on Friday March 27th from 10h30-12h.\n\nPLEASE NOTE: The Junior Quantum 
 Series are for gathering  the junior quantum community of master's stu
 dents\, PhDs and post-docs at EPFL\, to create a non-judgmental space were
  scientific ideas can be shared between peers. This event is not for Profe
 ssors or senior researchers. \n\nABTRACT: \nIn this talk\, I present a r
 ealization of the surface code on a rectangular lattice of qubits\, utiliz
 ing single-qubit and nearest-neighbor two-qubit Pauli measurements with th
 ree auxiliary qubits per plaquette. The code is optimized for Majorana-bas
 ed hardware. It has a short operation period of 4 steps and is designed to
  handle problematic error types well\, in particular so-called “hook err
 ors” and the presence of dead components. I also discuss the constructio
 n of an efficient decoder for the code\, and show the simulated code perfo
 rmance under the standard circuit noise model. The performance simulations
  indicate that the code has a high threshold of about 0.66% and is competi
 tive with the current state-of-the-art quantum error correcting code for M
 ajorana-based hardware\, the 4.8.8. Floquet code. I also briefly discuss h
 ow the strategy for stabilizer measurements here used for the surface code
  can be used more generally\, and in particular how it was also used to co
 nstruct a measurement-based code on only eight qubits\, which to our knowl
 edge is the smallest fault-tolerant error correcting Floquet code.\n
