Turing Chemputer Skill: Programmable Chemical Synthesis

Status: ✅ Production Ready Trit: 0 (ERGODIC – coordinator) Color: #26D826 (Green) Principle: Chemistry as computation Frame: XDL programs executed on modular hardware

Overview

Turing Chemputer coordinates chemical synthesis as program execution. Using XDL (Chemical Description Language), any synthesis protocol becomes an executable program on modular robotic hardware.

1. XDL: XML-based chemical programming language
2. Chempiler: Compile XDL to hardware instructions
3. Modular hardware: Reactors, filters, separators as primitives
4. Turing completeness: Loops, conditionals, recursion

Core Framework

<!-- XDL: Chemical Description Language -->
<Synthesis>
  <Hardware>
    <Reactor id="reactor1" volume="100 mL"/>
    <Filter id="filter1"/>
    <Separator id="sep1"/>
  </Hardware>
  
  <Procedure>
    <Add reagent="A" vessel="reactor1" amount="10 mmol"/>
    <Add reagent="B" vessel="reactor1" amount="12 mmol"/>
    <HeatChill vessel="reactor1" temp="80 °C" time="2 h"/>
    <Filter from="reactor1" to="filter1"/>
  </Procedure>
</Synthesis>

def compile_xdl(xdl: str) -> HardwareInstructions:
    """Chempiler: XDL → executable hardware program."""
    tree = parse_xdl(xdl)
    graph = build_synthesis_graph(tree)
    return optimize_and_schedule(graph)

Key Concepts

1. XDL Programming

class XDLProgram:
    def __init__(self):
        self.steps = []
    
    def add(self, reagent: str, vessel: str, amount: str):
        self.steps.append(Add(reagent, vessel, amount))
    
    def heat(self, vessel: str, temp: str, time: str):
        self.steps.append(HeatChill(vessel, temp, time))
    
    def filter(self, from_vessel: str, to_vessel: str):
        self.steps.append(Filter(from_vessel, to_vessel))
    
    def loop(self, times: int, body: list):
        """Turing-complete: iteration."""
        self.steps.append(Loop(times, body))
    
    def conditional(self, sensor: str, threshold: float, then: list, else_: list):
        """Turing-complete: branching."""
        self.steps.append(Conditional(sensor, threshold, then, else_))

2. Hardware Abstraction

class Chemputer:
    def __init__(self, hardware_graph: nx.DiGraph):
        self.graph = hardware_graph
        self.state = ChemicalState()
    
    def execute(self, program: XDLProgram):
        """Execute XDL on hardware."""
        for step in program.steps:
            self.validate_hardware(step)
            self.execute_step(step)
            self.update_state(step)
    
    def validate_hardware(self, step):
        """Check hardware connectivity and capacity."""
        if not self.graph.has_path(step.source, step.target):
            raise HardwareError("No fluidic path")

3. Synthesis Graph Optimization

def optimize_synthesis(xdl: XDLProgram) -> XDLProgram:
    """Optimize for time, yield, and hardware utilization."""
    graph = to_dag(xdl)
    
    # Parallelize independent operations
    parallel = find_parallel_steps(graph)
    
    # Minimize transfers
    optimized = minimize_transfers(graph)
    
    # Schedule for hardware
    return schedule(optimized, hardware_constraints)

Julia Scientific Package Integration

From julia-scientific skill – molecular representation evolution connects chemputer synthesis to learnable chemistry:

# Retrosynthesis via GNN → XDL generation
using MolecularGraph, GraphNeuralNetworks

function retro_to_xdl(target_smiles::String, model::GNNModel)
    mol = smilestomol(target_smiles)
    fg = featurize(mol)

    # GNN predicts synthetic route
    precursors = model.predict_precursors(fg)
    reactions = model.predict_reactions(precursors, mol)

    # Generate XDL from predicted route
    generate_xdl(reactions)
end
