PlanqTN Studio

Getting started with PlanqTN Studio

The idea with PlanqTN Tensor Studio is that you can start to explore the framework via small examples, including calculating weight enumerators and distance for small networks.

As a demo, let's create the Steane code out of two [[6,0,3]] tensors!

  1. Navigate to planqtn.com. No need to register, unless you want to calculate weight enumerators, which we won't need for this tutorial!
  2. Grab two pieces of the [[6,0,3]] tensors on to the canvas
  3. Connect the two logicals legs and calculate the parity check matrix - we can already see that this is the [[8,0,4]] encoding tensor of the Steane code.
  4. Add in an "identity stopper" to any of the legs to get the subspace parity check matrix

Well done, now you've used the quantum LEGO framework, created a topological code via a generalized concatenation procedure!
