With this release, an alternative way of specifying quantum circuits is introduced. Similar to Qiskit (the well-known quantum computing framework written in Python), a circuit can now also be constructed by successively entering instructions. The circuit is then layed out automatically. This gives less control about the precise positioning of gates but allows for faster construction and also composition of sub-circuits. Moreoever, it is now easy to create templates for generic types of circuits.

For this, the submodule Tequila has been added to Quill. Tequila also features two built-in templates: tq.graph-state() and tq.qft().

#import "@preview/quill:0.4.0": *
#import tequila as tq

#quantum-circuit(
  ..tq.graph-state((0, 1), (1, 2)),
  ..tq.build(y: 3, 
      tq.p($pi$, 0), 
      tq.cx(0, (1, 2)), 
    ),
  ..tq.graph-state(x: 6, y: 2, invert: true, (0, 1), (0, 2)),
  gategroup(x: 1, 3, 3),
  gategroup(x: 1, y: 3, 3, 3),
  gategroup(x: 6, y: 2, 3, 3),
  slice(x: 5)
)

Sounds very cool!
