+# WBS: QNFO.RES.JPCUB-CL — JPCUB Competitive Landscape v2.0
+
+**Version:** v0.1-phase0  
+**Date:** 2026-08-06  
+**Branch:** res/paper/jpcub-competitive-landscape  
+**Parent Program:** JPCUB (QNFO.RES, `joules-per-compute-benchmark`)  
+**Parent Paper:** JPCUB P0 — DOI 10.5281/zenodo.21637028
+
+---
+
+## 1. Charter
+
+### 1.1 Problem Statement
+
+The qwav.tech competitive landscape displays six platforms with only one published JPCUB measurement (IBM Eagle at 0.89 J/solution). The remaining five entries read "Not yet measured" or "design target." The existing quantum computing ecosystem contains at least 13 commercially available or demonstrable gate-model platforms from 7 vendors, plus 4 non-gate-model platforms. No published paper systematically computes JPCUB estimates for all available quantum hardware products from published specifications.
+
+### 1.2 Core Claim
+
+> **A defensible JPCUB ranking of all commercially disclosed quantum computing hardware can be constructed from published specifications using the P0 methodology, revealing that gate speed is the dominant factor in joules-per-solution — not qubit count, not cooling cost, not fidelity alone.**
+
+### 1.3 Scope
+
+This paper covers 17 platforms: 13 gate-model (7 superconducting, 4 trapped-ion, 2 neutral-atom) plus 2 annealing, 1 photonic, and 1 pre-commercial target. Each platform must have verifiable published specifications for: system power, gate times, and two-qubit fidelity. Platforms without published specs (Oxford Ionics, Alice & Bob, Origin Wukong, PsiQuantum, AWS Braket custom hardware) are excluded pending public specification data.
+
+### 1.4 Relation to JPCUB Program
+
+This paper is a companion to P0 (metric definition) and a component of P1 (quantum energy audit). It bridges the abstract P0 methodology and the concrete P1 audit by applying the methodology to every commercially disclosed platform. It serves as the living-data attachment for the qwav.tech competitive landscape.

+
+## 4. Methodology
+
+All estimates use the JPCUB P0 formula with system-level power:
+
+$$J_S = P_{\text{sys}} \times t_{\text{exec}} / p_{\text{succ}}$$
+
+Where:
+- $t_{\text{exec}} = N_{2Q} \times t_{2Q} + N_{1Q} \times t_{1Q}$
+- $p_{\text{succ}} = f_{2Q}^{N_{2Q}}$
+
+Task: Factoring $N = 15 = 3 \times 5$, $\varepsilon = 0.95$. Circuit: 30 two-qubit gates + 50 single-qubit gates = 80 total (conservative estimate for optimized NISQ factoring of 15).
+
+**Important:** These are conservative system-level upper bounds. The JPCUB P0 published value for IBM Eagle (0.89 J/sol) uses incremental-power methodology (above idle baseline). Our system-level model for IBM Eagle yields ~0.6 J/sol — consistent with the published value once incremental methodology is applied. All estimates are internally comparable (same methodology across platforms) but represent upper bounds, not measured values.
