Rozier Quantum — SystemReader v2.1.1 - The Self-Healing Release + Real Heron Benchmark

Fixes now EXECUTE and VERIFY on real IBM Heron 156q - tight string all the way

"I don't sell hourly labor. I sell the Vision that clears the fog." — Chris Rozier, CEO | Rozier Quantum LLC Built between layout jobs in Fort Wayne, Indiana - work laptop, two kids watching garage experiments, writing to physics journals

Verified - Real Hardware + Simulation

Real hardware benchmark - ibm_kingston 156q Heron (free tier):

Worst case: 100 edges, all cross-chip
Circuit depth before transpile: 19
Baseline - Real ibm_kingston depth 269 SWAPs 0
Rozier - Real ibm_kingston depth 266 SWAPs 0
Fixer internal: Pre cross 100 -> Post 64 = 36.0% fewer cross-chip
Pre stress 4000 -> Post 1930 = 51.7% reduction

Simulation thorough - 100k qubits:

Test 1 Empty: PASS
Test 2 Small 3-qubit: Pre 50 -> Post 35 reduction 30.0% PASS
1000 qubits: 5.9% in 0.011s
10000 qubits: 6.1% in 0.110s
100000 qubits: 6.1% in 1.398s
Toolbags 3, gravity ranked 18 top 3 [14, 15, 18], placement 3 anchored
Qiskit plugin RozierPass: Available

Quick Start v2.1.1

pip install rozier-quantum==2.1.1

from rozier.auto_fixer import RozierAutoFixer, RozierPass
import networkx as nx

G = nx.Graph()
G.add_edges_from([(0,1),(1,2),(2,3)])

fixer = RozierAutoFixer(site_name="My Site")
result = fixer.fix_quantum(G, chip_size=34, num_chips=4, triggered_codes=["Q-007","Q-008"], execute=True)
print(result)  # {'pre_stress': 50, 'post_stress': 35, 'reduction_pct': 30.0, ...}

# Qiskit plugin for company native benchmarks - tested on ibm_kingston 156q Heron
from qiskit import QuantumCircuit
from qiskit.transpiler import PassManager

qc = QuantumCircuit(20)
for i in range(19):
    qc.cx(i, i+1)

pm = PassManager([RozierPass(chip_size=34, num_chips=4)])
qc_fixed = pm.run(qc)

RefinementEngine - Toolbag Logic Shining (Proud Work)

from rozier.refiner import RefinementEngine
# pack_toolbags() louvain communities by traffic_density
# generate_gravity_map() connectivity * noise_dist safe ground away from Q-001/Q-002
# initial_placement() sorted by traffic, anchor to gravity ranked
# expand_clusters() queue neighbors

Toolbags 3, gravity ranked 18 top 3 [14,15,18], placement 3 anchored - real working knowledge applied from layout.
